Sunol Regional Wilderness

For the cacophonous and chromatic convergence of water and wildflowers in spring, few places compare to Sunol Regional Wilderness, where Alameda Creek thunders through Little Yosemite Gorge below Canyon View Trail, a prime promenade for mavens of floral marvels. But Sunol is a treat in any season. A hike up Indian Joe Creek Trail to Cave Rocks, farther up to Vista Grande and back down by way of Flag Hill offers a memorable bang for the aesthetic – and aerobic – buck.
