Another week, another virgin Trailblazer hike leader. Ron is no virgin, though- he's been having his way with the California trails for years! Let him have his way with you on this 7 mile loop hike with 1600' of elevation gain.

To the Chippewa Indians of Michigan and Wisconsin, Mishe Mokwa meant a great bear. To the Weekday Trailblazers of So Cal, it means a great hike with amazing natural features.

We'll proceed via the Triunfo Pass/Backbone Trail, passing Sandstone Peak, the highest point in the Santa Monica Mts, and the Boney Mt area. On a clear day, you can see LA, Ventura, and the Channel Islands. The inspiring views continue as we move through the Circle X Ranch to Tri Peaks and Big Dome.

On our way back, we'll follow Carlisle Canyon and its weathered red volcanic rock formations. There are views across the canyon of the caves and crevices of Echo Cliffs, a physics marvel named Balanced Rock, and a huge, fractured boulder known as Split Rock (it lost the battle with physics). You are likely to see rock climbers dangling from the Echo Cliffs.

This is national and state parkland, with trails fairly well marked. We will go on some minor paths also. They vary from single track to fire road to pure rock, from fully shaded to fully exposed. It can get windy at the summit, so prepare accordingly. No dogs allowed on this hike.

Because there's so much to see, this hike may take a little longer than our normal hikes. Plan on getting back to the cars at 2, and consider anything earlier a gift.


From the 101, take Westlake Blvd (Rte 23) south 8 miles to Mulholland. Turn right on Mulholland for about half a mile. Turn right on Little Sycamore, which becomes Yerba Buena Road after 2 miles, for 4 miles.

At Triunfo Pass, there is a large parking area on the left, and a smaller one on the right at our trailhead. This lot is at a high point of Yerba Buena Road, not the parking area farther on downhill for Sandstone Peak. If you are at the Sandstone Peak trailhead parking area or the ranger station you have gone too far.

From Pacific Coast Highway, take Yerba Buena Road (near Neptune's Net), 7 miles (passing the rangers station and the Sandstone Peak parking area), OR Hwy 23 (Decker Cyn- 4 miles west of Point Dume) , turn onto Mulholland and as above.

Do not use the address listed above as an exact location.

This is a very slow driving route (narrow, with sharp turns) and will probably take 30-40 minutes from the 101 or PCH to the lot. Give yourself plenty of time, then take it. Cell reception is marginal up there, and we'll have to get moving if you're not there on time.



The hike host is a volunteer and not responsible for the group. Safety should be a priority for everyone in the group. Please treat this meet-up as hiking with a group of friends. If you become fatigued and unable to continue the hike, it is expected you will advise the hike host of this and return to our starting point on your own. If you are able to proceed, it is expected that you will maintain line of sight with other members of the group at all times and help to promote the group’s safety and fitness goals.
