About Huckleberry Hot Springs
Huckleberry Hot Springs, Wyoming is a geothermal spring on Polecat Creek in the John D. Rockefeller Jr. Memorial Parkway, near Flagg Ranch in Teton County between Grand Teton National Park and Yellowstone National Park. Soaking in the spring is prohibited by NPS regulation, has been enforced since 2014, and the water has been found to contain dangerous pathogens. Do not enter the water. The trail to view the springs remains open for hiking.
The NPS began enforcing the existing prohibition against entering geothermal features in 2014, citing resource damage including trampled vegetation, worn rocks, changed water composition, and formation of social trails. In 2016, NPS water monitoring detected E. coli in excess of EPA limits and naegleria fowleri, a single-celled organism that causes primary amebic meningoencephalitis, an almost always fatal brain infection. The same monitoring also detected these pathogens at nearby Polecat Springs. The trail to view Huckleberry Hot Springs is approximately 0.6 miles one-way from the trailhead near Grassy Lake Road, with 36 feet of elevation gain. The spring site is within the John D. Rockefeller Jr. Memorial Parkway, administered by Grand Teton National Park, and a park entry fee applies.

Safety & Etiquette
Huckleberry Hot Springs Safety Information
Do not enter Huckleberry Hot Springs or any geothermal feature in the John D. Rockefeller Jr. Memorial Parkway. Soaking is prohibited by NPS regulation since 2014 and violators face fines. Water monitoring has detected E. coli exceeding EPA limits and naegleria fowleri in the spring water. Naegleria fowleri causes primary amebic meningoencephalitis, a nearly always fatal brain infection contracted when contaminated water enters the nasal cavity. Do not swim, wade, or allow spring water near your nose or mouth. These hazards are not seasonal. They apply regardless of weather, water temperature, or apparent conditions at the site.
The trail involves a Polecat Creek crossing that can run high and fast in spring and early summer. Test depth before crossing and turn back if the water is above knee height or moving strongly. Waterproof footwear is recommended. Ground near the springs can be soft and unstable. Stay on the established trail to protect vegetation and footing.
Bears, moose, and other wildlife are present throughout the parkway. Carry bear spray and make noise on the trail. Cell service is limited near Flagg Ranch. Download offline navigation before arriving. The park road in this area is closed in winter. The Flagg Ranch Visitor Center is approximately 1 mile east of the trailhead.
Do not touch any geothermal feature, pool, or outflow in the Grand Teton and Rockefeller Parkway area. Polecat Creek, which receives geothermal inflow and mixes with cold water, remains technically open to recreation. The creek temperature varies by section and season.
