Swimming Holes in Illinois

Swimming Holes in Illinois

Illinois is not a state with a long list of famous swimming holes, and we would rather be honest about that than pad this page with places that do not exist. The natural swimming worth seeking out is concentrated in the far south, where the forested ridges and hollows of the Shawnee National Forest create creeks, small lakes, and recreation-area beaches. Our directory currently tracks two swimming destinations in Illinois, both in the southern part of the state, and this guide covers them along with the seasons, hazards, and access details you should understand before you go.

If you are open to traveling, neighboring states offer more variety. The Ozarks in Missouri, the southern hill country of Indiana, the rivers of Kentucky, and the lakes of Wisconsin all add options within a reasonable drive of much of Illinois. You can also browse the full directory, find spots near you, or compare states from the states overview.

Illinois Swimming Holes

Both of our Illinois listings sit in the southern third of the state, near Carbondale, Murphysboro, and Harrisburg.

Shawnee National Forest Swimming Destinations

Shawnee National Forest Swimming Destinations covers the creek and lake swimming spots scattered across the Shawnee National Forest in southern Illinois. The standout here is Pounds Hollow Recreation Area, which has a designated swim beach on a small, scenic lake. As a developed recreation area on national forest land, Pounds Hollow is the closest thing Illinois has to an official, managed natural swimming spot, though that does not mean it is lifeguarded. Beyond Pounds Hollow, the forest holds quieter creek pools and lake shorelines that draw locals on hot days. Most national forest land is free to access, but some developed recreation areas may charge a day-use fee, so verify current conditions and fees with the U.S. Forest Service before you go.

Kincaid Lake Spillway

Kincaid Lake Spillway covers the tiered cascade below Kinkaid Lake near Murphysboro. Official pages use the Kinkaid spelling. DNR lists the dam and spillway as water-resource facilities, but current swimming permission remains unverified. Treat the gallery as scenery and terrain context, not a child-friendly swimming recommendation or proof of today's access. Confirm the signed approach and parking before travel.

Where to Swim by Region

Southern Illinois and the Shawnee National Forest

This is the heart of natural swimming in Illinois. The Shawnee National Forest spreads across the southern tip of the state, between the Mississippi and Ohio rivers, and its terrain of wooded hills and rock formations is unlike anything in the flat farmland farther north. Both of our listings are here: the Shawnee National Forest Swimming Destinations (including the Pounds Hollow beach) and the Kincaid Lake Spillway near Carbondale and Murphysboro. If you are planning an Illinois swimming trip, this is where to base yourself.

The rest of the state

Central and northern Illinois are dominated by agriculture, cities, and managed lakes, and our directory does not currently list natural swimming holes there. That does not mean none exist, but we would rather not invent entries. If you live in those regions, the spots above are a road trip, and the neighboring states linked at the top of this page may be closer than you expect.

When to Go

Plan around the chosen recreation area's current opening schedule and conditions, not a statewide guarantee of stable water. A warm summer day does not establish swimming permission or safe water entry at the spillway. Check weather, manager notices and any designated beach's current status before travel.

Safety and Hazards

Your safety is your own responsibility at every spot on this page. Key hazards in Illinois:

• No lifeguards. Assume none of these locations are guarded, including the Pounds Hollow beach. Watch children closely and never swim alone.
• Spillways and currents. The Kincaid Lake Spillway involves moving water, which can be far stronger than it looks. Avoid spillways during or after high flow, and never put yourself where a current could pull you toward an outflow.
• Water quality. Check available local advisories. Clear water or a fixed wait after rain is not evidence that water is suitable for swimming.
• Submerged hazards. Natural water bodies hide logs, rocks, and uneven bottoms. Enter feet-first and never dive into water of unknown depth.
• Lightning. Summer thunderstorms can build fast. Leave the water at the first sign of lightning or thunder and wait it out under proper shelter.

A general note on quarries: Illinois has many former rock and gravel quarries, and they can be tempting on a hot day. Unmanaged quarries are dangerous, with frigid deep water, sudden drop-offs, and submerged debris. We do not list or endorse swimming at unmanaged quarries.

Access, Fees and Permits

Confirm Shawnee recreation-area costs and closures with the U.S. Forest Service. For Kincaid Lake Spillway, use the specific manager's guidance rather than assuming all land around the lake is national forest. DNR's lake overview describes several land managers. Spillway-specific fees and swimming permission were not verified. DNR's activities page distinguishes named recreation-area amenities and prohibits camping on DNR property. Book authorized camping separately; it is not spillway access permission.

Frequently Asked Questions

Does Illinois have a lot of swimming holes?
No. Illinois is not known for natural swimming holes, and our directory tracks just two, both in the south. The state is mostly farmland and managed lakes; the natural swimming worth a trip is concentrated in the Shawnee National Forest. Neighboring states like Missouri, Indiana, and Kentucky offer more variety.

Where is the best place to swim outdoors in Illinois?
The far south, in and around the Shawnee National Forest. The Pounds Hollow Recreation Area has a designated swim beach on a small lake, making it the most established natural swimming spot in the state. The Shawnee National Forest Swimming Destinations listing covers it and other creek and lake spots nearby.

Is there a lifeguarded swim beach in Illinois's natural areas?
There is a designated swim beach at Pounds Hollow in the Shawnee National Forest, but you should not assume any lifeguard is on duty. Treat all the spots on this page as unguarded and swim within your limits.

Do I have to pay to swim in Illinois?
Check the selected recreation area's current charges. We have not verified spillway-specific entry or parking fees, so this guide no longer promises free access there. The lake has several managers; ask about the exact destination.

When is the best time to swim in Illinois?
Use a designated area's current season, access notices and conditions rather than a fixed statewide date range. No suitable swimming season has been verified for the spillway.

Is it safe to swim at the Kincaid Lake spillway?
We have not verified current swimming permission, safe depth or water quality at the spillway. Photos and informal visitor use do not establish those facts. Do not treat this guide as clearance to enter the water, stand under the cascade or cross barriers.

Responsible Recreation and Leave No Trace

• Pack it in, pack it out. These spots have little or no trash service. Carry out everything you bring, including food scraps.
• Respect boundaries and signs. Obey closures and access restrictions, and do not trespass on private land to reach water.
• Protect water quality. Skip soaps and shampoos in natural water, and choose reef- and water-safe sunscreen.
• Tread lightly. Stay on established paths where possible, keep noise down, and give wildlife and other visitors plenty of space.
