America’s national parks are famous for their hiking trails, scenic overlooks, and wildlife viewing opportunities, but hidden within these protected landscapes are some of the most pristine swimming spots you’ll find anywhere on the continent. These aren’t the crowded beach areas or developed recreation zones that appear on park maps, but rather the secluded pools, cascading waterfalls, and crystal-clear basins that require a bit of effort to reach.
Most park visitors stick to the main attractions and miss these refreshing retreats entirely, which is exactly what keeps them special. Here’s a list of 20 secret swimming spots in national parks, each offering a chance to cool off in some of the most beautiful natural settings America has to offer.
Emerald Pools, Zion National Park
The middle pool at Emerald Pools offers the perfect swimming spot that most visitors walk right past on their way to the more famous upper pool. Tucked behind a curtain of water from the falls above, this natural basin stays cool even during Utah’s scorching summer months.
The sandstone walls create a natural amphitheater that feels like your own private oasis, complete with a waterfall shower.
Havasu Falls Pool, Grand Canyon National Park
Getting to this turquoise paradise requires a 10-mile hike into the Havasupai Reservation within Grand Canyon National Park, which explains why it feels like discovering a hidden civilization. The mineral-rich water creates that impossible blue-green color that doesn’t look real until you’re floating in it.
The limestone terraces form natural steps into the pool, making it feel like someone designed the perfect swimming spot and then hid it at the bottom of one of the world’s most famous canyons.

Devil’s Bathtub, Hocking Hills State Park
This smooth sandstone pool near Old Man’s Cave gets its name from the way water has carved a perfectly round basin into the rock over thousands of years. The water stays surprisingly warm thanks to the sun-heated stone, making it feel like nature’s version of a hot tub.
Most hikers rush past on their way to the main waterfall, missing this intimate swimming spot that’s tucked away like a secret room in a mansion.
Sliding Rock, Pisgah National Forest
While technically in a national forest rather than a national park, this 60-foot natural water slide ends in a deep pool that’s become legendary among locals who’ve been keeping it quiet for generations.

The pools above and below McKinney Falls offer two completely different swimming experiences in the same location. The upper pool is shallow and warm, perfect for families and lounging, while the lower pool is deep enough for serious swimming and cliff jumping.
