Terraces for viewing
Follow the designated Mammoth paths rather than crossing fragile thermal ground. These are not bathing pools; Boiling River cannot be used for swimming after the flood. [2][5]
Mammoth & the northern range guide
Start with the travertine terraces and Gardiner’s North Entrance. Plan Lamar as a separate northern journey, and distinguish a park overnight from Gardiner or Paradise Valley.

Northern access differs in winter
The Gardiner–Mammoth–Tower Junction–Cooke City corridor is generally open to regular vehicles year-round, weather permitting. Roads east of Cooke City and the wider interior loop have separate closures. [1]
Three different settings
Mammoth is inside Yellowstone. Gardiner is beyond the North Entrance. Sage Lodge is in Pray in Paradise Valley, well farther north; it is not a short walk or a Mammoth overnight. [1]
