Sibley Volcanic Preserve

Featured hike
Mile:
0.0: Walk up the paved road to the right of the Visitor Center.
0.1: The road splits at an unsigned junction. Stay to the right on the paved trail.
0.3: Signed junction. Turn right onto narrow Round Top Loop Trail.
0.3: The Bay Area Ridge Trail/Skyline Trail departs to the right, descending to Huckleberry Preserve. Stay to the left on Round Top Loop Trail.
0.3: A dirt spur trail from the paved road enters from the left. Keep going to the right.
0.6: Crest and path heading to the right. Continue straight.
0.8: The trail descends to a T junction. Walk straight toward a fenced viewpoint and stop #4 on the volcanic tour. Walk back toward the previous junction and turn left to visit the labyrinth.
0.9: Labyrinth and old quarry pit. When ready, return uphill to the previous junction, then go straight on Round Top Loop Trail.
1.3: Round Top Loop Trail heads back to the trailhead, left. Continue straight on Volcanic Trail.
1.5: Junction near a watering trough. Stay to the right, then walk a few feet to a second junction. Bear right (ignore another trail to the right which ends at a gate).
1.6: Second labyrinth. When ready, return to Volcanic Trail, then turn left and return to the junction with Round Top Loop Trail.
1.9: Junction with Round Top Loop Trail. Turn right.
2.3: Multi-trail junction. A paved road returns back to the trailhead, straight, and uphill to a dead-end, left. The trail to the right splits almost immediately, and both paths return to the trailhead, but in a much more intimate way than the road. Turn right ("to Visitor Center"), then right again.
2.6: The trail ends at a gate a few few from the parking area.

Getting there:
From CA 24 in Alameda County, exit Claremont (exit 3). Drive about 1.5 miles northeast on Claremont Avenue to a major intersection, with Ashby. Continue straight through the light, then turn right to remain on Claremont Avenue (Claremont Boulevard veers left). You should see a brown "parks" sign for Tilden and Sibley Parks, then pass the back on the Claremont Hotel on the right. Continue on Claremont about 2 miles to the intersection with Grizzly Peak Boulevard. Turn right and drive about 2.4 miles to the intersection with Skyline Boulevard. Turn left onto Skyline, and almost immediately, after 0.1 mile, turn left into the preserve entrance.
