Some national parks are famous for their views. Others are famous for the things you can actually do there. And if you’re anything like me, the parks that you love the most are the ones where the experience goes beyond a scenic overlook (not that I don’t love a scenic overlook – I do).

Across the U.S., there are national parks that have some really cool things to do. You can rappel down towering cliffs, kayak through sea caves, soak in geothermal rivers, climb frozen waterfalls, and even watch a waterfall turn into fire. I’ve visited dozens of national parks, and these are the places that consistently make people say, “Wait… you can do that in a national park?”

This list is all about unforgettable experiences. The kind you talk about for years after the trip is over.

These are 25 of the coolest national parks in the U.S., paired with a uniquely awesome thing to do in each.

Some are adrenaline-filled. Some are quietly magical. All of them will change how you think about what a national park experience can be.

1. Zion National Park, Utah | Rappel Down 200-Foot Cliffs

Zion is famous for its soaring sandstone walls, narrow slot canyons, and heart-pounding vertical relief. It has some of the most iconic hikes in the country. However, while hiking Angels Landing is iconic, the real adrenaline rush happens when you go over the edge.

Canyoneering in Zion means rappelling down cliffs that drop hundreds of feet, sliding through sculpted rock chutes, and wading through emerald pools deep in slot canyons. This was my first experience canyoneering and it got me hooked!

The sensation of leaning back over a sheer wall with nothing but rope between you and the canyon floor is unforgettable. It’s technical, thrilling, – a little scary, I’m not going to lie – and incredibly immersive.

Few national park experiences put you inside the landscape quite like this.

2. Grand Canyon National Park, Arizona | Ride Rapids in a Wooden Boat

The Grand Canyon is one of the most recognizable landscapes on Earth, but seeing it from the rim is just the beginning. Down below, the Colorado River carves through the canyon with immense power, shaping the walls you see from above. The scale feels even more dramatic when you’re at river level.

Riding the rapids in a traditional wooden dory is as close as you can get to experiencing the canyon like the earliest river runners. These handcrafted boats are basically the same ones James Powell used. They bounce, spin, and surge through massive whitewater, making every rapid feel raw and real. It’s loud, wet, and exhilarating.

Floating through towering canyon walls while navigating churning rapids is pure Grand Canyon magic (and you’ll have expert guides do the rowing – you just need to bail like crazy when you go through the rapids). This is one of my all favorite national park experiences!

3. Grand Canyon National Park, Arizona | Walk Over a Canyon

The Grand Canyon is all about perspective, and there’s no better way to challenge yours than stepping out into thin air.

From the rim, the canyon already looks impossibly vast – but walking over it takes things to another level. Suddenly, there’s nothing beneath your feet but open space.

The glass-bottomed Skywalk extends out over the canyon, letting you look straight down thousands of feet to the Colorado River. It’s equal parts thrilling and nerve-wracking, even for people who don’t think they’re afraid of heights. The views are jaw-dropping in every direction. It’s a short walk, but the adrenaline lasts a long time.

➡️ Book a trip from Las Vegas to the Skywalk

---

4. Grand Teton National Park, Wyoming | Dog Sledding 

Grand Teton’s jagged peaks rise straight up from the valley floor, creating one of the most dramatic mountain skylines in the country. It’s fun to visit in the summer, of course, but in winter, the park transforms into a quiet, snow-covered wilderness where the silence feels almost unreal.

This is when the Tetons feel especially wild.

Dog sledding through the snowy landscape is both peaceful and exhilarating. The dogs are powerful, focused, and clearly love what they’re doing, and you feel that energy the moment you start moving.

Gliding across frozen terrain with the Tetons towering above you feels like stepping into another era. It’s an unforgettable way to experience the park beyond summer hiking.

➡️ Book a dog sledding and snowmobile day trip

➡️ Read my Guide to Visiting Grand Teton in Winter for essential information for a winter visit.

5. Mammoth Cave National Park, Kentucky | Try Spelunking

Above ground, Mammoth Cave National Park looks calm and forested, but below the surface lies the longest cave system in the world.

This underground landscape is filled with twisting passages, chambers, and hidden geological wonders. It’s a completely different national park experience.

There are several cave tours you can take. The most extreme spelunking is on the Wild Cave Tour , which takes you off the paved tour routes and into tight crawls, muddy tunnels, and pitch-dark chambers. You’ll scramble over rocks, squeeze through narrow openings, and truly explore the cave like an adventurer.

It’s physical, immersive, and a little intimidating – in the best way. Few parks let you explore so deeply beneath the surface.

---

6. Yellowstone National Park, Wyoming, Montana and Idaho | Soak in a ‘Boiling’ River

Yellowstone feels like another planet, with steaming geysers, bubbling mud pots, and rainbow-colored hot springs. Geothermal heat is everywhere, reminding you that the earth is very much alive beneath your feet. It’s dramatic, powerful, and endlessly fascinating.

In select areas, hot springs mix with cold river water to create natural soaking spots that are perfectly warm. The Boiling River is one of them. It’s not actually boiling, but is warm.

Sitting in a flowing river while steam rises around you is surreal. You’re literally bathing in geothermal energy while surrounded by wild landscapes. It’s one of the strangest – and most relaxing – experiences in any national park.

7. Redwood National and State Parks, California | Kayak California’s Only Free-Flowing River

Redwood National and State Parks are best known for their towering trees, but the landscapes here are surprisingly diverse. Foggy forests give way to wide rivers and remote coastal scenery. It’s a quieter, more understated kind of beauty.

Kayaking the Smith River – California’s only major free-flowing river – lets you experience this park from a completely different angle.

The water is crystal clear, often revealing rocks and fish below your kayak. You’ll paddle beneath forested hills with almost no development in sight. It’s peaceful, pristine, and incredibly scenic.

---

8. Redwood National and State Parks | Climb the Tallest Trees on Earth

These parks protect the tallest trees on the planet, some stretching more than 350 feet into the sky. Walking among them already feels humbling, like being in a natural cathedral. But there’s a way to go even higher.

With a guided climb, you can ascend into the canopy of a giant redwood. From above, the forest looks completely different—layers of green stretching into the distance. It’s quiet, surreal, and surprisingly serene. Very few places on Earth let you experience a forest from this perspective.

Note that this is not technically in the national park. Redwood climbing tours are on private property in the Santa Cruz mountains.

---

9. Hawai’i Volcanoes National Park, Hawaii | Stand On The Edge of an Active Volcano

Hawaiʻi Volcanoes National Park is one of the most dynamic landscapes in the U.S. Lava fields, steaming vents, and volcanic craters make it feel raw and ever-changing. This is geology happening in real time.

Standing on the edge of an active volcano is both awe-inspiring and slightly unnerving. You can feel heat rising from below and see steam escaping from cracks in the earth.

It’s a powerful reminder that the ground beneath you is constantly being reshaped. Few national parks feel this alive.

---

10. Hot Springs National Park, Arkansas | Get a Natural Spa Treatment

Hot Springs National Park blends historic architecture with natural geothermal features. Unlike most parks, this one is woven directly into a city, giving it a unique feel. Beneath the streets, thermal waters have been flowing for thousands of years.

Soaking in these mineral-rich waters is both relaxing and steeped in history.

There are eight historic bathhouses on Bathhouse Row. The historic bathhouses offer a classic spa experience using naturally heated spring water. It’s soothing, indulgent, and surprisingly therapeutic. This is one national park where relaxation is the main attraction.

---

11. Arches National Park, Utah | Stargaze

Arches is famous for its surreal red rock formations and gravity-defying stone arches. During the day, the landscape feels otherworldly. At night, it somehow gets even better.

With minimal light pollution, Arches offers incredible stargazing. The Milky Way stretches across the sky, often framed by iconic arches in the foreground. The contrast between glowing stars and dark desert rock is stunning. It’s quiet, peaceful, and absolutely unforgettable.

12. Denali National Park, Alaska | See the Northern Lights

Denali is vast, wild, and dominated by North America’s tallest mountain. The landscape feels untamed, with wide-open tundra and distant peaks. It’s a place where nature clearly sets the rules.

When conditions are right, the Northern Lights dance across the sky in waves of green and purple.

Seeing them here feels especially magical because of how remote and dark the park is. There’s nothing but wilderness in every direction. It’s one of the most awe-inspiring natural shows on Earth.

---

13. Channel Islands National Park, California | Dive in Giant Kelp Forests

Channel Islands National Park protects a wild, ocean-focused landscape just off the California coast. Above water, the islands feel rugged and remote. Below the surface, they’re bursting with life.

Diving into the giant kelp forests feels like entering an underwater forest. Tall kelp stalks sway with the current while sea lions and bright orange Garibaldi fish dart between them. The light filtering through creates an almost magical atmosphere.

It’s one of the most unique diving experiences in the world. This was one of my bucket list dives and I loved every second of it!

➡️ See my Guide to Channel Islands Kelp Diving for more details

---

14. Channel Islands National Park, California | Kayak Through Sea Caves

The coastline of the Channel Islands is carved with dramatic cliffs, arches, and caves. From land, many of these features are inaccessible. From the water, they’re yours to explore.

Kayaking through sea caves lets you paddle into echoing chambers and beneath rock arches shaped by waves. The experience is thrilling, especially when the ocean swells gently lift and lower your kayak.

You’ll see the islands from a perspective few visitors get. It’s adventurous, scenic, and unforgettable. Tours go to several caves, including tunnels and large caves with hidden beaches inside. Very cool!

➡️ Read my Guide to Channel Islands National Park for practical info on visiting the park

15. Great Sand Dunes National Park, Colorado | Sand Boarding

Great Sand Dunes is full of surprises, with massive dunes rising against a backdrop of snow-capped mountains. It feels almost impossible that this landscape exists in Colorado. The contrast alone makes it special.

Sand boarding down towering dunes is pure fun. You hike up soft sand (that’s the less fun part), strap on a board, and fly downhill in a rush of adrenaline.

It’s like snowboarding, but warmer and way sandier. This park turns the desert into a playground.

---

16. Biscayne National Park, Florida | Snorkel Sunken Shipwrecks

Biscayne National Park is mostly underwater, protecting coral reefs, clear waters, and historic wrecks. From the surface, it looks calm and tropical. Below, it’s a fascinating underwater museum.

Snorkeling shipwrecks here lets you swim through history. Coral-covered hulls are now home to colorful fish and marine life. It’s eerie, beautiful, and surprisingly accessible. Few national parks offer this kind of underwater exploration.

---

17. Acadia National Park, Maine | See the First Sunrise in the USA

Acadia’s rocky coastline and granite peaks give it a rugged, coastal feel. The Atlantic Ocean plays a huge role in shaping the park’s character. It’s especially magical in the early morning.

At certain times of year, Cadillac Mountain is the first place in the U.S. to see the sunrise. Watching the sky change colors over the ocean is a peaceful, powerful experience. It feels symbolic and special. Few moments are more memorable than starting the day this way.

➡️ Read my Guide to the Cadillac Mountain Reservation System for essential information

18. Acadia National Park, Maine | Eat Popovers

Acadia isn’t just about scenery – it’s also about classic New England charm. After hiking and exploring, food becomes part of the experience. And there’s one treat everyone talks about.

Popovers at Jordan Pond House are legendary. Light, airy, and served warm with butter and jam, they’re the perfect reward after a day in the park.

Sitting by the pond at an outside table on a warm sunny day with mountains behind you makes them taste even better – and is one of my absolute favorite things to do in Acadia. It’s a delicious tradition you won’t want to skip.

➡️ Get a detailed Itinerary for Acadia National Park

19. Kenai Fjords National Park, Alaska | Whale Watching

Kenai Fjords is defined by ice, water, and wildlife. Glaciers flow down from the mountains straight into the sea. The landscape feels dramatic and alive.

Whale watching here is extraordinary. You might see humpbacks breaching or orcas slicing through the water. The combination of massive glaciers and enormous marine life is breathtaking. It’s one of the best places in the U.S. to see whales in the wild.

---

20. Crater Lake National Park, Oregon | Cruise Inside a Volcano

Crater Lake is famous for its impossibly blue water and sheer caldera walls. The lake fills an ancient volcano, making it both beautiful and geologically fascinating. From the rim, it already looks unreal.

Taking a boat tour lets you experience the lake from inside the volcano itself. The water is incredibly clear, and the scale of the caldera becomes even more apparent.

You’ll visit Wizard Island and learn about the park’s volcanic past. It’s serene, dramatic, and totally unique.

---

21. Olympic National Park, Washington | Explore Tidal Pools

Olympic National Park is incredibly diverse, with mountains, rainforests, and rugged coastline. Along the coast, the ocean shapes everything. Timing your visit with low tide reveals a hidden world.

Tidal pools here are packed with colorful sea stars, anemones, and crabs. Exploring them feels like discovering a secret ecosystem. Every pool is different, and you never know what you’ll find. It’s hands-on, fascinating, and perfect for curious explorers.

22. Glacier National Park, Montana | Horseback Riding

Glacier is known for its alpine scenery, glacial valleys, and pristine wilderness. The landscapes feel expansive and untouched. It’s a park made for slow, immersive exploration.

Horseback riding lets you travel through this terrain the old-fashioned way. You’ll move quietly along trails, surrounded by peaks and wildflowers. The pace allows you to truly take it all in. It’s peaceful, scenic, and deeply connected to the park’s history.

There are several outfitters in different sections of the park that offer guided horseback rides, including Lake MacDonald and Many Glacier.

23. Pictured Rocks National Lakeshore, Michigan | Climb a Frozen Waterfall

Pictured Rocks is famous for colorful sandstone cliffs along Lake Superior. In winter, the landscape transforms completely. Waterfalls freeze into towering columns of ice.

Ice climbing these frozen waterfalls is an adrenaline-filled experience. You’ll scale shimmering blue ice with the lake frozen behind you. It’s cold, challenging, and incredibly rewarding. This is one of the coolest winter adventures in the Midwest.

Check out Michigan Ice Fest for details.

---

24. Mesa Verde National Park, Colorado | Explore an Ancient Palace

Mesa Verde protects some of the best-preserved cliff dwellings in North America. These ancient structures are tucked into sandstone alcoves high above the canyon floor. The history here feels tangible.

Exploring Cliff Palace lets you walk through rooms built over 700 years ago.

It’s not technically a palace, but is still super cool. You climb ladders, pass through narrow tunnels, and imagine life in this remarkable place. It’s immersive and deeply moving. Few parks connect you to human history like this.

➡️ See my Guide to Mesa Verde National Park for more information about the park

---

25. Yosemite National Park, California | Watch a Firefall

Yosemite is iconic for its granite cliffs, waterfalls, and sweeping valleys. It’s dramatic in every season, but winter brings something special. For a short time each year, nature puts on a show.

During a handful of February (and sometimes September if the waterfall is flowing) evenings, the setting sun can turn Horsetail Fall into what looks like flowing lava.

The waterfall glows orange and red, creating the famous “firefall.” It’s brief, unpredictable, and absolutely mesmerizing. Seeing it feels like witnessing magic.

➡️ See my Guide to Yosemite National Park for more information about the park

One of the best things about U.S. national parks is that no two experiences are ever quite the same. One trip might have you standing at the edge of an active volcano, while another has you floating through a kelp forest or watching the first sunrise hit the country.

If you’re planning your next trip and want something more memorable than “nice views,” start here. Pick one park, choose the experience that makes your heart beat a little faster, and build your trip around it.

Because the coolest national parks aren’t just the ones you see—they’re the ones you do.
