9 Illinois Swimming Holes That Belong On Your Summer Bucket List

Illinois has a wild little summer secret: some of its best swims feel nothing like the Midwest most people imagine. Think cool canyon pools tucked beneath sandstone walls, quiet forest lakes with sandy edges, and bright Lake Michigan beaches backed by city energy.

This state hides a surprising mix of places where a towel, water shoes, and a cooler of lemonade can turn an ordinary hot day into a mini adventure. Each spot brings its own mood, with shaded trails, rocky creek beds, calm lake coves, or breezy shoreline views adding to the fun.

For anyone craving a refreshing escape without leaving Illinois, these nine swimming spots deserve a place on the summer bucket list.

Few places in Illinois reward a short hike quite like Bell Smith Springs Recreation Area, a hidden sandstone wonderland tucked inside Shawnee National Forest near Eddyville in Pope County.

The natural swimming hole here sits within a dramatic canyon carved by Bay Creek, where towering rock formations and overhanging bluffs create a scene that feels more like Arkansas than the Midwest. The water is cool, clear, and genuinely refreshing on a sweltering July afternoon.

The trail system around Bell Smith Springs offers multiple loop options, but visitors should be prepared for creek crossings, slippery rock, and uneven canyon terrain.

You will pass natural bridges, fern-covered hollows, and small waterfalls before arriving at the main swimming area. Bring water shoes because the creek bed gets slippery, and the rocks along the banks are perfect for sitting and soaking up some sun between swims.

This spot is especially popular on summer weekends, so arriving early in the morning gives you the best chance of finding a quiet patch of shoreline. Dogs are welcome on a leash, making it a great outing for the whole family.

The Shawnee National Forest surrounding the area is home to remarkable biodiversity, and birders often spot warblers and herons along the creek corridor. Camping is available nearby at Redbud Campground, so you can easily turn this into an overnight adventure.

Bell Smith Springs is one of those rare places that manages to feel completely wild while still being genuinely accessible, and it earns every bit of its cult following among Illinois outdoor enthusiasts.

2. Jackson Falls, Shawnee National Forest

Somewhere between a swimming hole and a geological masterpiece, Jackson Falls near Eddyville in the Shawnee National Forest is the kind of place that makes you stop and stare before you even think about getting in the water.

A series of tiered sandstone ledges drop water into a wide, shallow plunge pool, creating a natural shower that hikers and swimmers have been loving for generations.

The rock formations here are genuinely stunning, with swirling patterns and deep reds and oranges carved into the stone over millions of years.

Getting to Jackson Falls requires a short but rugged hike of about half a mile from the trailhead parking area. The path drops down into a canyon, and the falls reveal themselves gradually as you descend.

The plunge pool at the base is best enjoyed in late spring and early summer when water levels are higher, though the rock formations alone make a visit worthwhile even in drier months.

The ledges above the falls are popular for scrambling, and the wide flat rocks beside the pool are ideal for laying out a towel and enjoying the cool, shaded canyon atmosphere. Bring sturdy footwear because the wet sandstone can be slippery underfoot.

Nearby, you can explore additional Shawnee National Forest destinations, including Garden of the Gods by car.

Jackson Falls does not get the same foot traffic as some other Shawnee spots, which means you often get the canyon largely to yourself, and that kind of solitude on a hot summer day is genuinely priceless.

Kinkaid Lake is one of southern Illinois’s best-known outdoor recreation spots, and the spillway area just below the dam near Murphysboro in Jackson County is a popular but informal place to cool off.

Water releases from the spillway create a natural current that swimmers use to float downstream, and the rocky pools below the dam stay refreshingly cool even during the hottest stretches of August. The surrounding landscape is lush, green, and quintessentially southern Illinois.

Beyond the spillway, Kinkaid Lake itself stretches across more than 2,700 acres and is ringed by forest, making it one of the most scenic reservoirs in the state.

The main beach area near the campground is sandy and well-maintained, with gradual entry points that work well for families with young children. Paddleboats and kayak rentals are sometimes available during peak season, adding another layer of fun to a full day on the water.

The lake sits within the Shawnee National Forest boundary, meaning the surrounding trails and natural areas are easily accessible for those who want to combine swimming with hiking. Fishing is also excellent here, with largemouth bass and crappie drawing anglers from across the region.

Camping at the Kinkaid Lake Recreation Area puts you right on the water, and waking up to a sunrise over the lake before an early morning swim is one of those experiences that sticks with you.

Plan for a full day, because once you arrive at Kinkaid, leaving early feels like a genuine waste of good summer time.

Cedar Lake in the Shawnee National Forest near Dixon Springs in Pope County is the kind of swimming spot that feels like it was designed specifically for a perfect summer afternoon.

The lake sits in a narrow valley surrounded by forested ridges, and the reflections of the tree-covered hillsides in the calm water give the whole place a postcard-quality look that you almost cannot believe is real.

A sandy beach area provides easy access for swimmers of all ages, and the water stays comfortably cool throughout the summer months.

Although Cedar Lake covers about 1,750 acres, its forested shoreline and designated beach area can still feel peaceful compared with busier regional reservoirs.

On a weekday morning, you might have the entire beach to yourself, with nothing but birdsong and the sound of water lapping against the shore for company.

The surrounding forest offers shaded picnic areas perfect for a midday break between swims, and the trails nearby are worth exploring if you have energy to spare after your time in the water.

Cedar Lake is a designated swimming area, so there are no motorized boats allowed on the lake, which keeps the water clean and the atmosphere calm. This is especially appreciated by families with young kids who want a safe, quiet environment without the wake and noise of powerboats.

Pounds Hollow Recreation Area near Elizabethtown in Hardin County is one of the most beloved swimming destinations in all of southern Illinois, and for very good reason.

The centerpiece is a gorgeous 25-acre lake ringed by sandstone bluffs and old-growth forest, creating a natural amphitheater effect that makes the whole place feel like a private retreat.

The combination of swimming and hiking in one location makes Pounds Hollow an ideal full-day destination rather than just a quick dip stop.

Camping is available at the adjacent Pounds Hollow Campground, and securing a site close to the water means you can walk to the beach in minutes each morning.

The area is also famous for its proximity to the Garden of the Gods Wilderness, so ambitious visitors often combine a Pounds Hollow swim day with a sunrise hike through those iconic rock formations.
