Visitors with campground or lodging reservations or wilderness permits will be allowed to enter the park during delays. In order to avoid delays, visitors are encouraged to enter the park as early in the morning as possible. One way sections exist on the Hetch Hetchy Road , and vehicles exceeding 25 feet in length are permanently restricted. Temporary weight restrictions have been lifted on the Wawona Road , that portion of Highway 41 inside the park. Do not leave food in your car.
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.
