Hot Spring Basin Group
Hot Spring Basin Group erupts at 198 degrees Fahrenheit at 8,388 feet elevation in Yellowstone's northeastern wilderness, positioned 14.5 kilometers from the Northeast Entrance Road. This thermal complex produces near-boiling water that runs 165.8 degrees above the frigid ambient air temperature, creating dramatic steam displays visible across the remote basin. The feature sits deep in backcountry territory accessible only through extended wilderness expeditions.
The thermal group occupies an isolated basin in the Absaroka Range at the extreme northeastern reach of Yellowstone's volcanic caldera. At 8,388 feet elevation, the landscape endures severe alpine conditions with annual average temperatures of 32.2 degrees Fahrenheit, 27.4 inches of precipitation, and 135.7 inches of snowfall. Subalpine forests of whitebark pine and spruce give way to open meadows and exposed ridgelines. The basin collects thermal discharge that flows through mineralized channels before joining cold headwater streams. Surrounding peaks rise above treeline, with glacial cirques and talus slopes characterizing the rugged topography. The thermal activity creates localized microclimates supporting unique vegetation communities.
This thermal group is appropriate only for highly experienced wilderness travelers with advanced navigation and survival skills. Obtain backcountry permits from park rangers and carry detailed topographic maps, compass, and GPS units. The nine-mile approach requires multi-day expeditions with full self-sufficiency including bear-resistant food storage. Visit late July through August when snow permits passage; carry four-season gear as conditions remain harsh even in summer. Be prepared for stream crossings and off-trail travel through dense forest and steep terrain. Tower Fall Campground 20 kilometers southwest provides developed facilities for trip preparation before entering the wilderness.
The name describes the geographic feature: a cluster of thermal springs concentrated within a distinct drainage basin. Historical documentation is limited given the extreme remoteness. The feature appears in systematic geothermal surveys conducted during the 1960s-1970s as scientists mapped Yellowstone's complete hydrothermal inventory. The area achieved permanent protection with the park's 1872 establishment and remains in primitive condition with no development.

Overview Tower Fall Campground—elevation 6,600 feet (2012 m)—is on the north side of the steep, winding, road to Dunraven Pass. The campground is near the Tower General Store and Tower Fall. The Lamar Valley, with spectacular wildlife viewing opportunities, is nearby as are several Day Hikes in the Tower and Northeast Area. Roosevelt Lodge, a short drive from the campground, offers dining and horseback riding. For reservations at the campgrounds managed by Yellowstone National Park Lodges (F...
At 8,388 feet, Hot Spring Basin Group is in high-altitude territory where the air is noticeably thinner. Soaking in hot water accelerates dehydration and can amplify altitude effects like headache and fatigue. UV radiation is roughly 34% stronger here — wear sunscreen even on overcast days and take breaks from the water to rehydrate.
