If lounging under a cloudless sky after an ice-cold dip in a peaceful pond seems like a little slice of paradise, it’s closer than you think. But so is a chilly dip in a hidden mountain lake, or a revitalizing splash in a good ol’ fashioned secret lake – you just have to know where to look! Or, sneak off without the kids to find your own private Idaho (because you deserve a day off, too!). Either way, these gorgeous Idaho swimming holes are perfect for a weekend getaway, a simple day trip, or a quick pit stop on your next adventure.
This outlet lake on the east side of Priest Lake will take a beautiful Sunday afternoon drive and a slightly confusing hike to get to, but it's oh-so worth it.
Hailey's treasured Wood River Trail is a delight to stroll in every season. But come summer, you might find a few extra folks congregating in certain areas where the bridges and banks lend themselves to diving (or cautiously tiptoeing) into the water.
Idaho's Seven Devils don't get a lot of recognition for their hidden lakes the way the Sawtooths do... but they should! Both the Upper and Lower Cannon Lakes will take some intense hiking to reach, but being that you'll be swimming just above the deepest canyon in the country, we say it's totally worth it.

4. Box Canyon Springs, Hagerman
Box Canyon Springs Preserve, Wendell, ID 83355, USA
We've talked about the endless wonders of the Hagerman Valley before, and Box Canyon Springs in nearby Thousand Springs State Park is just one of them! Located on its own nature preserve within the park, and just 20 miles northwest of Twin Falls, this natural spring is the 11th largest in the U.S.
Accessible, recently renovated with a new sandy beach and picnic area, and just off of Boise's iconic Greenbelt, Quinn's Pond, located near Esther Simplot Park, is a massive 22-acre stretch of water that is perfect for cooling off without treading on the heels of Boise River floaters.
Dierkes Lake is hands-down one of the best Idaho swimming holes. Its a special hideaway in near Shoshone Falls that not only offers a distinct, sanctioned kiddie pool, but multiple man-made and natural high dives for the adventurous spirit. This swimming hole does cost a nominal fee to use, but is well worth it for the scenery and isolated location alone.
Tucked away in the scenic Bitterroot Mountains and surrounded by the Clearwater National Forest, this chilly lake is a popular destination for fishing but offers multiple private outlets for swimming.
This gorgeous aquamarine lake is not only set in a picture-perfect location, it's also gorgeous in every season and just a short drive from Burgdorf Hot Springs if you feel like taking a relaxing soak before or after your mountain swim.
Redfish Lake is an Idaho gem and definitely one of the most beautiful places in the state. Pristine water, beautiful mountain views, and a chilly dive that will wake you up and cool you off all at the same time! But how about its little sister lake? The scenery isn't as wide open as Redfish itself, but the more secluded setting is absolutely dreamy.
10. St. Anthony Sandbar
St. Anthony Sandbar, South 3rd East, Saint Anthony, ID, USA
While away the summer at St. Anthony Sandbar, a favorite swim spot in Eastern Idaho that features a floating dock, diving board, and an old-school metal water slide, alongside its namesake sandy beach.
With so many natural hot and cool springs, waterfall watersheds, and natural swimming holes to choose from, the sunbaked body in search of a spot to cool off will have no trouble finding the perfect place to make some summer memories. Northern Idaho’s lakes and beaches are an absolute dream, the wild, glacial corners of Central Idaho are pristine and worth the challenging hikes, and the volcanic recesses of Southern Idaho were seemingly made for finding your own secret swimming hole. Which region will you choose?

Idaho Swimming Holes
Lysa Allman-Baldwin|June 15, 2022
Are there any Idaho swimming holes located in state parks?
Absolutely. One of the most popular in The Gem State is called Beaver Bay Beach, located within Farragut State Park. It’s a lovely four-mile loop hike to get to it and a pretty easy one for hikers of all abilities. The views are magnificent and you may want to camp nearby to visit the falls more than once.
What is good hiking spot in Idaho?
There are so many, some also featuring some of the best swimming holes in Idaho. One of them is in the Seven Devils Mountains. Here you will find multiple trails that traverse this massive park bordering the state of Oregon. While here, be sure to trek to the Heavens’ Gate Lookout from where you can take in spectacular views of four states: the surrounding Idaho landscape, of course, and parts of Washington, Oregon, and Montana.
