Mammoth Hot Springs is located 5 miles (8 km) south of Gardner, MT, 49 miles (79 km) northeast of the West Yellowstone, MT and 47 miles (76 km) west of Yellowstone's Northeast Entrance. The North Entrance is the only park entrance open all year.

All other park roads and entrances are open seasonally.

Hiking trails offer a closer look at nature yet it is wise to take care when selecting a path; Mammoth area trails vary in length and grade. The easy, 1-mile Lower Terrace Trail is predominately boardwalk but is only wheelchair accessible at Liberty Cap. The 1-mile (1.6 km) Wraith Falls Trail is graded easy. The 5-mile Beaver Ponds Trail is graded moderate. The 11-mile (17.7 km) Sepulcher Mountain Trail is graded strenuous. Bighorn Pass, Fawn Pass, Sportsman Lake and Yellowstone River trails are lengthy backcountry treks (permits required for backcountry camping). Ranger-led programs are offered from June through September and late December through late February. Traveling to Mammoth in winter? Don't despair. There are a variety of x-country trails to choose from. NB: Check the ranger station for trail closings before you set out. Be sure to pull your car off the roadway when stopping at roadside turnouts and overlooks.
