In Tuolumne Meadows, daytime highs have ranged from 65 to 80, with overnight lows in the 40s. 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.
All park roads are open for the season.
All entrances to Yosemite National Park are open 24 hours a day, weather permitting. Reservations are not needed to enter the park in 1998. Private vehicles are allowed to drive into and around Yosemite Valley. Day use visitors to the park may experience periods of restricted access at any busy time during the summer to allow congestion to dissipate. These delays may last from thirty minutes to several hours and assure that resources are protected and visitors receive a quality experience.
