Bears can smell food in and break into vehicle trunks. Visitors need to store all food, ice chests, and odorous items in metal food storage boxes or hard-sided cabins. Once bears become conditioned to human food, they become unnaturally aggressive and must be killed. The weather in the park has been mostly sunny. In Tuolumne Meadows, daytime highs have been in the low 70s, with overnight lows in the 30s.
Camping is permitted only in designated campgrounds.
