Access plan
Access, shuttle, and map
Launch below Green River Ferry and continue downstream to Houchins Ferry for a quieter, longer Mammoth Cave Green River run. The direct Mammoth Cave gauge anchors the route, but the current July 14 stage sits above the broad beginner-friendly band and should be treated as consequential experienced water.

Access caveats and watch for
Access caveats
- Launch and load on the downstream side of Green River Ferry so you do not interfere with ferry operations.
- Houchins Ferry has the easiest overnight support in this route family, but the ramp and campground still sit inside a managed park setting with posted quiet-hour and facility rules.
- On-route camping requires a valid riverside permit and is flow-dependent. Use only legal gravel-bar or low-bank sites allowed by park rules.
- This longer stretch is less traveled than Dennison-to-Green River Ferry, so groups should be more self-sufficient about shuttle, weather, and emergency planning.
Watch for
- Ferry traffic at the launch, plus submerged trees, logjams, gravel-bar shifts, back channels, and drifting debris throughout the run.
- Higher water above about 15 ft, when the route becomes more consequential, and launch closures at or above 20 ft.
- Cold springs, exposed sun, limited cell service, and fewer nearby bailout options than the shorter park segment.
- Camping mistakes: rising overnight water, unsecured boats, and unauthorized stops without a valid permit.
