Switchbacks and Swimming Holes
Hike, Picnic, and Swim at Cull Canyon Regional Recreation Area
Hike hard, play hard! This 7-mile out-and-back in Cull Canyon Regional Recreation Area is a great workout with payoff vistas and a relaxing post-hike picnic and dip in the water.
From the parking lot, follow signs for the Chabot To Garin Trail as they head north and cross Columbia Drive. This section of trail is a hilly jaunt through the forest, lined with dainty three-cornered leek flowers. As the trail crisscrosses over Cull Creek, rock-hop across the water and keep an eye out for banana slugs enjoying the damp soil.
Steep switchbacks lead into the hills, where exotic red columbine mingle with vivid lupine flowers. Small breaks in the trees gift hikers with their first views of the surrounding hills.
At the intersection with the horse farm, bear right to pass through the farm gate and stay on the Chabot To Garin Trail. A gentle slope brings hikers to the high point: a grassy meadow at 1,000 feet elevation. Enjoy views of the Diablo Mountains and Lake Chabot far in the distance. Then retrace the route back down to the parking lot.
Just south of the parking lot is the entrance to the Swim Lagoon, a family-friendly watering hole for a post-hike cooldown and picnic. Fees apply (check the East Bay Parks website for updated prices) and include swim access and use of the sandy beach and picnic areas.
The Cull Canyon Regional Recreation Area is located at 18825 Cull Canyon Road in Castro Valley.
The parking lot is open from 8 a.m. to 10 p.m. Map. Dogs welcome on trails, but not at the swim lagoon.
