Southern California resorts convert to summer activities in May. You can find lifts running in summer at Snow Summit and Mt. Baldy, along with cool mountain elevations to beat the summer heat.

Big Bear Mountain Resorts convert to summer operations usually by late May. The golf course and 300-yard driving range, which sit at a 7,000 feet in elevation, open for the summer season. The nine-hole course located at the base of Bear Mountain features a pro shop, restaurant, and rentals of clubs and carts.

The Snow Summit Scenic Sky Chairlift runs daily for sightseeing, hiking, and mountain biking. The chairlift speed slows for summer to 15 minutes to reach the top. Sightseers can ride down the chairlift, while hikers may opt for a wildflower lined trail back to the base area or a ridgeline traverse with views of Big Bear Lake and the Santa Ana River Valley.

Mountain bikers at Snow Summit have the option of lift-accessed single-track trails or gentle base area terrain on the Bristlecone Trail or Towne Trail. Only cross-country bikes are permitted on the lift; downhill specific bikes are banned. Riders may access Forest Service trails, but not the ski runs for riding. Mountain bike rentals are available.

Mt. Baldy operates weekends and holidays for summer. The Top of the Notch Restaurant opens for summer dining with big views of surrounding mountains. Chair 1 runs for sightseeing, hiking, and mountain biking.
