Getting There

Las Trampas Regional Wilderness offers 5,342 acres of wilderness and an expanded trail system that allows hikers and horseback riders to enjoy its remote and rugged areas. The park's size and terrain allow visitors a feeling of privacy and escape from urban hustle and bustle. Carry plenty of drinking water. Two major Bay Area faults--the Las Trampas and Bollinger faults--account for the uplift and exposure of four well-defined geological formations. The Orinda formation holds remnants of ancient beach and shoreline. The El Sobrante formation consists of several fossil-bearing compressed rock layers. The Pinole Tuff is of volcanic origin.

No parking fee.

Some part of the trail was muddy due to recent rainfall, but overall it was great.

Giving it 3 stars because I wasn't able to finish due to being charged at by a large Newfoundland looking dog, black and white. I've worked with dogs for almost 20 years and this guy was not happy about me being on his trail. He came out of nowhere and there were no humans in sight or ear-shot. Pretty terrifying experience, I'm glad I did not have to pepper spray him. If your dog can be weary of strangers at times, do not let him off leash when hiking.

HikingGreat!

One of our favorite trails so far. Gives you good huffing and puffing during the uphill and gets you good workout. Chemise joins with Las Trampas Ridge trail on the top. Amazing views all through the trail. Very good down hill.

Beautiful views throughout this hike, and great diversity of landscape including brown, undulating hills peppered with green trees. A few groups of cows along the way. I rated it at four because the uphill climb is a killer, Extremely long and extremely steep. If you want to get your heart going and have a good workout, it’s a good one; if you want more of a leisurely hike, I would take a different route.

Lots and lots of cow/horse poop and cows on the path. Super easy flat trail with a nice shaded part along the stream (dried out). No cell coverage for most of it, including on the drive in. Dog friendly and not too many other people.

Chamise is less trafficked, a narrow path, and ascends over 600' in less than a mile. Pretty challenging but so worth it. Great views of Mt. Diablo, shady, and it smells great! It's named after the Chamise shrub covering this hill. There is also coyote mint, clarkia, and sticky monkey flower still blooming in late June. Once you hit Bollinger Creek loop, there is just a little more of a climb but it's shady. Then the descent is exposed with wide trails and a little more crowded.
