Box Canyon State Park: How to Hike to the Canyon Floor + Swimming Spots

Tucked away in southern Idaho, Box Canyon State Park is a scenic spot that often flies under the radar. With its striking turquoise spring, dramatic canyon walls, and crystal-clear water, this park offers one of the most unique hikes in the region. Whether you’re looking to trek down to the canyon floor or cool off with a swim, here’s everything you need to know for planning your visit.

Box Canyon State Park is just one of the six units that make up Thousand Springs State Park. This natural wonder is a hidden gem in Idaho’s greater Twin Falls area and really must be seen to be believed!

Hidden amongst the flat farmland and dairy pastures is a secluded canyon where crystal clear water seeps from rock walls into a brilliant blue pool where it then flows out towards the Snake River. This spring flows at a rate of 180,000 gallons per minute making it the 11th largest spring in the United States!

You will notice Water Veronica (a bright green plant) growing in the blue pool which is an indicator of stream health signifying that the water here is very pure.

So how do you get to Box Canyon and where is the best place to view this amazing natural wonder? Well, you can type Box Canyon State Park into google maps which will take you through agricultural land to a small parking lot in Wendell.

This parking lot is easy to miss, especially if no one else is here yet so keep your eyes peeled for a small sign letting you know you have arrived at Box Canyon. There are two parking lots, one right off the road, and another past the sign about 3/4 of a mile down a dirt road.

At first it may seem like there couldn’t possibly be anything impressive in the vicinity but after a short walk you’ll see the land open up and at the bottom of this wide chasm is a sparkling pool of light blue water.

It’s a mind blowing contrast seeing the flat and featureless farmland against the lush plant life flourishing below, and seeing the river’s crystal clear waters winding through the canyon.

Once you’re done taking in the views and snapping photos, prepare to be even more impressed once you get down to the canyon floor!

How to hike down to Box Canyon

After parking at the Box Canyon Springs trailhead, follow the wide, well-worn path across a flat, open field. In the distance, you’ll see fencing that marks private property—it may look like you’re heading the wrong way, but you’re on the right track.

When you reach the fence, you’ll come to a small ladder. The ladder will help you climb over the barbed wire safely. Once you get on the other side of the fence, continue along the dirt trail until you reach the canyon rim.

Follow the trail along the canyon rim, and eventually you’ll come to a point where the trail descends into the canyon. The descent involves a series of rocky switchbacks—but don’t worry—there is a steel cable handrail bolted into the rock wall to help you get down.

Although the hike down is steep, it is short-lived and you’ll quickly find yourself at the canyon floor, where the trail becomes flat and easy again.

From here, follow a narrow path as it winds through thick vegetation and eventually leads to a gushing spring-fed waterfall. The water here is a glowing, luminescent blue, and you can admire it from several vantage points, including its base.

Box Canyon Falls is stunning and easily one of the most photogenic waterfalls in the Twin Falls area! If you’re pressed for time, the waterfall makes a great turnaround point.

Otherwise keep hiking a few minutes farther to see the canyon floor widen and discover inviting spots along the stream where you can take a dip in the cool spring water.

Best swimming spots in Box Canyon

There are several great spots for swimming in Box Canyon. After visiting the waterfall, continue following the trail until you cross a small wooden bridge to reach the opposite side of the stream.

Once across, keep walking until you come to a small sandy area along the riverbank. This makes for an ideal place to wade into the cool, clear water. If that spot is already occupied, don’t worry—there’s another sandy stretch just a bit farther down the trail.

If you’re just looking for a quick dip before heading back, keep an eye out for flat rocks between the wooden bridge and the sandy area where you can jump in. There are a few good entry points in this area, though they can be a little tricky to spot if the grass is overgrown, so take your time scouting a safe place to enter.

Keep in mind—the water here is ice cold, and it’ll definitely take your breath away when you first get in! But the reward is worth it! The water is unbelievably clear, especially on a sunny day. If you’re lucky, you might even spot a few curious trout swimming nearby.

Box Canyon is an out-and-back trail, so once you’ve had your fill of exploring and swimming, you’ll head back the same way you came.

If you’re wrapping up your visit in the late afternoon, consider sticking around for sunset—the view from the canyon rim is absolutely stunning, with golden light pouring over the cliffs and turquoise spring below.

Tips for hiking to Box Canyon State Park

Wear sturdy shoes. The trail down to the canyon floor is short but steep and rocky in places. Proper footwear with good traction is essential, especially when navigating loose gravel or uneven terrain.

Bring plenty of water. Southern Idaho can get hot and dry starting May through September. Hydration is key. If you’re in the market for a new water bottle, check out these sleek hydroflasks that will keep your drinks cold for hours!

Protect yourself from the sun. There is little shade along the trail, even on the canyon floor. Mineral sunscreen, sunglasses, and a hat, are must-haves.

Don’t forget insect repellent. Mosquitoes come out to play in the evenings. Bring mosquito repellent—like this DEET-free option made with lemon eucalyptus oil for a natural solution. This stuff works great!

Pack your swimsuit and a towel. If you’re planning to take a dip, be sure to pack a swimsuit and towel so you can enjoy the refreshing spring water.

Watch your step: While the main trail is relatively easy to follow, the descent into the canyon can be slick with loose rock. Take your time and consider using trekking poles for added stability.

Visit on a weekday. For a quieter experience, try to visit on a weekday. If you’re heading there on a weekend, be sure to arrive early—parking fills up quickly.

Always practice good trail etiquette and respect the land. The springs and surrounding area are fragile, so pack out everything you bring, avoid littering, and watch your step to protect the natural environment.
