Mammoth Cave’s underground rivers are no longer open to boaters—the last underground boat tours were discontinued in the early 1990s, and paddling is not permitted on any of the cave’s waterways. What you can do today is glimpse those mysterious waters on the seasonal River Styx Tour, a walking tour that brings you face-to-face with the cave’s active river system without a kayak or canoe in sight.
Exploring the Hidden Waterways of Mammoth Cave
Kentucky’s Mammoth Cave is famous for its vast underground labyrinth. But it also hides mysterious waterways that you can glimpse on the seasonal River Styx Tour. Here is what you will actually see—and where you can still get on the water above ground.
River Styx Spring
The River Styx Spring is where the underground river emerges.
- River Styx Spring: This spring is where the underground river surfaces. View the clear waters and feel the cool breeze as you explore the winding paths on the seasonal River Styx Tour. The tour is not a boat ride—it is a walking route that gives you a close look at the underground river from safe, designated walkways.
Echo River
Echo River is known for its serene waters and echoing chambers, but it is strictly off-limits to boats.
- Echo River: This river flows quietly through the cave. The echoes of your footsteps, not paddle strokes, will make you feel like you are in another world. The river is visible on certain cave tours, but no watercraft are allowed.
Green River
Green River runs through the heart of Mammoth Cave National Park. This is where you can actually launch a kayak or canoe.
- Green River: This river offers a mix of calm waters and gentle rapids. Paddle along the lush green banks and enjoy the diverse wildlife. Unlike the cave’s underground streams, the Green River is open for recreational boating year-round, with several public access points within the park.
Nolin River
Nolin River is for those seeking a more challenging adventure. Its swift currents and rocky terrain make for an exciting boat trip—and it is entirely above ground.
- Nolin River: Navigate the twists and turns of this river, feeling the thrill of the fast-moving water. The surrounding cliffs and forests add to the sense of adventure. This river is a popular spot for kayaking and canoeing, especially in the spring when water levels are higher.
Turnhole Bend
Turnhole Bend is a secluded spot on the Green River, not underground.
- Turnhole Bend: This bend in the river provides a quiet retreat. Paddle through the calm waters and take in the rock formations and lush vegetation. It is a great place for a half-day float, with no rapids to worry about.
Blue Hole
Blue Hole is a spot on the Green River. Its crystal-clear waters and vibrant blue hue make it a breathtaking sight—but do not confuse it with the cave’s underground formations.
- Blue Hole: This spot is perfect for a relaxing boat ride on the Green River. The clear, blue waters are mesmerizing, and the surrounding scenery is stunning. It is a popular swimming and picnicking spot, so bring your gear and stay a while.
