Event Notes:

Tromp Through The Traps (Las Trampas)


Join us for a hike through Las Trampas as we climb up and down the peaks and valleys. A hiker's choice of a Moderate 6 mile/1700 ft out and back or a Challenging 8 mile/2400 ft loop hike, both hikes will explore Las Trampas Peak.

Hike begins heading northwest up Lower Bollinger Creek Loop, right on Bollinger Creek Loop towards the ridge, veer left on up to the ridge, left on Las Trampas Ridge Trail, left on Las Trampas Peak View Trail for a view from the top. Short hikers may take an extended snack break here. All hikers will continue left on Ridge Trail another mile to the junction of Madrone Trail.

Short hikers will turn back here, returning along the same route to the parking area. You may choose to hike back along Upper Bollinger Creek Loop trail for some variation along the final 3/4 mile.

The long hike will turn right on Madrone Trail, taking a break somewhere along the way (TBD, X marks the spot). Turn right at the first junction to head south on Madrone Trail. Make a hard right at Corduroy Hills Trail. At the next junction, take either way, they both loop around to the same spot. Continue up on the single track, left on a short spur near the top to the Eagle Peak overlook. Continue on Corduroy Hills, left at Las Trampas Ridge Trail, right at the fork onto Chamise. Turn left on Mahogany Trail for a lovely walk through the canyon along the crick, taking care of your footing. Continue straight where Trapline enters from the left until you reach Chamise Trail again, following it left and downhill toward the road. Before the gate, turn right on Bollinger Creek Loop which parallels the road, then left down to the parking area. If this trail looks like the surface of the moon, you may skip it and walk along the road instead.

Dogs welcome, especially Buster. Facilities at trailhead only. As always, the route will be marked with flour arrows to guide your way. Detailed maps available.
