Fall 2022 Update:
Due to problems with the drain field, the Dump Station at Henrys Lake State Park remains closed and will likely be closed for the 2023 season as well.
Alternate Dump Stations are:
- Bing Lemke Forest Service Dump Station, Last Chance, 20 miles south of the Henrys
- Ashton Visitor Center, 43 miles south
- Grizzly RV is available in West Yellowstone, 15 miles east.
The only sewage dump at the park will be the FULL hook-up sites.
We are sorry for the inconvenience.
