Las Trampas Peak hike
When thinking of a summit in the East Bay most people default to Mount Diablo. But just west lies the vast Las Trampas Regional Wilderness and its namesake summit, with views galore and no crowds. Reach the peak on a 3.8-mile (round-trip) trek through a mix of woodlands, chaparral and grassland. Start on the Chamise Trail and hike 1.4-miles up moderate switchbacks bordered by coast live oak, showcasing views of Las Trampas Ridge to the east. At the junction with the Las Trampas Ridge Trail, veer left and enter the tree-cover of California bay, canyon live oak, and hillside gooseberry. Here you'll see the most notable foliage, stunning madrone and manzanita trees with smooth chocolate-colored bark growing over a canyon's edge. Continue up Las Trampas Ridge Trail as it converts to a fire road and passes spectacular vistas of Moraga Valley and the Berkeley Hills. When you reach a gate, swivel left for a quick 0.1-mile climb to the 1,827-foot peak of Las Trampas—360-degree views span Mount Tamalpais, Mount Diablo, Rocky Ridge, and the Bay, to name a few! Retrace your steps to the Las Trampas Ridge Trail junction and continue downhill on the Bollinger Canyon Trail—a gentle 1.5-mile descent among open, grassy hills. Tramptastic!

From Interstate 680 South in San Ramon, take the Crow Canyon Road exit and head west about a mile until you see Bollinger Canyon Road. Take a right on Bollinger Canyon and follow the road 4.5-miles until you dead end into a parking lot. The Chamise trailhead is located just outside the parking lot, back on Bollinger Canyon Road. Bicycles aren't allowed on the Chamise Trail or on the single-track portions of Las Trampas Ridge Trail, but cyclists can reach Las Trampas Peak by taking Bollinger Canyon Trail out and back. Dog friendly!
