Basin and Lodge Capacity

Lots at Lake Mary and the Main Lodge frequently reach capacity by mid-morning during peak summer and winter months. Consider using the free Eastern Sierra Transit authority buses to reach trailheads without searching for space.

Early Alpine Starts

Afternoon thunderstorms are common in the High Sierra during summer; plan to finish exposed ridge hikes by noon. In winter, lift lines are generally shortest immediately at opening or during the lunch hour.

Seasonal Road Closures

Tioga Pass and Reds Meadow Road close annually for winter; these routes are not accessible by vehicle once heavy snow arrives. Always check Caltrans for current chain requirements and road status.
