Crazy Peak lies on private land within Gallatin National Forest, so the summit itself is not open to public access; the Crazy Mountains around it are an island range of the Montana Rockies. The name is shared with the range, and the peak is the highest point in Montana north of the Beartooth Mountains, 50 miles south.

Crazy Peak lies on private land within Gallatin National Forest, so access to the summit requires permission from the landowner; the nearest public approaches are long cross-country routes. The small glacier on the northeast slope and the 2,100 m rise above the Yellowstone River Valley mean snow and ice can persist. Carry a map and compass, as trails are scarce.
