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. Hours: Jan 1 - Feb 13: 8am - 5:30pm Feb 14 - Mar 8: 8am - 6pm Mar 8 - May 20: 8am - 7pm May 21 - Sep 3: 8am - 8pm Sep 4 - Nov 1: 8am - 7pm Nov 2 - Dec 31: 8am - 5:30pm

It is hard to find so don’t give up! Park on the street and make ur way to the trail GPS spot. You will see the post and know ur in the right spot. Enter to the left of a corner driveway.

The trail is pretty open. I missed a turn or two and took a longer path back to the start. It was good thou. Those trails are more covered and were more fun than an open path. All in all....pretty good.

good trail, mostly covered by trees which was a huge plus when hiking in summer. the trail has some character to it, mix of hard bush, open grassland, Rocky scrambles and some scenic outlooks. the view from top of cordorouy hills was great. overall it's a moderate climb with no section particularly straining you. started early at 7 and finished before 11. there are areas with cattle but mostly it's isolated. good number of local hikers too. overall I would look towards coming back sometime in winter

Simple straightforward trail hike and easily manageable. Had an 830am start and ended in time for lunch in downtown Danville. Beautiful view and weather was sunny 75F.

Fantastic hike that will kick your butt!

Did this hike again about 2 weeks back.. good trail about 5 Miles round trip. Going up went through the left side from the trail head to the Bollinger Creek Trail a paved trail to the top of the peak.. Took about 1 hr 30mins going up. Great views of Moraga, Orinda, Walnut Creek, Alamo, Danville, and Mount Diablo. On the way back coming down took the Chamise trail a true narrow trail over the ridge. Took about 1 hr 30 mins to get down..nice lil hike

it’s a nice trail. I don’t think it’s moderate, it’s closer to “hard” in my opinion. about 60% shade, but otherwise no shade at all. hiked during noon-3pm and 87F, doable but was hoping for more shade

Overall, really fun hike with amazing vistas and cool landscape changes. Highly recommend going counter clockwise in the loop as there are some parts of the trail that require you to climb up/over some rocks. I would not want to climb down these parts. I think the rocky parts and some very narrow paths with a steep drop-off to one side warrant the 'hard' rating. The elevation change is intense but well spread out. The first 2 miles were the toughest for us, but the views after mille 3 were well worth it. We saw a deer, lots of quail, squirrels, cows, and a gopher snake. Near the rocks, my husband swears he heard a rattlesnake rattle but we didn't stick around to see it. We were cutting it close to sunset so we took a ~0.5 mile shortcut on the very last leg. Excited to come back and do the full loop.

Nice trail - beautiful ridge topviews with Mt Diablo on one side distnca Bay view on the other

Nice views, lots of variation in elevation, vegetation. Great workout. If hot take at least 1 litre/person water.
Need shoes with good traction. Be careful of poison oak.

Great Hike. I'm by no means a pro or close to, but the hike was great until near the bottom of the Sycamore line. I felt like the overgrowth hadn't been cut back like it should've and some poison oak would on occasion hang over the trail and it was just GAH. Total grueling workout but my girlfriend and I loved the views. In retrospect, we would've stayed on the Rocky Ridge View trail and then enjoyed some In n Out down the street lol.. Also once you reach the Devil's Loop it is just intensely uphill. Respect for anyone who takes less than 10 or so breaks from that butt burner.

Easy until you hit Corduroy Trail. I highly suggest to follow the route as written. I doubt that I would have gotten down the rocky parts and up the "stairs" as those were pretty tall. I was able to enjoy Corduroy Trail by going counter clockwise as the directions state. I enjoyed the trails very much, lots of views and the trails were in okay shape. It has enough shade up to the last part as you descend. Take lots of water. I saw more people than animals. A few cows, but they didn't bother me nor I them.

The trails are not marked as well as others that I've been on. I totally missed my turn for Ringtail Cat trail and ended up south of the Ringtail trail head and ended up on Camille. I had to walk down Camille, take the Iron Horse trail back to Hemme. There are a lot of unmarked single tracks and I had taken one up to the top when I first started out, but couldn't find it on the loop back. My fault, so it added a little bit more to the hike.

I would think this would be a very pretty trail after some rains to get the water in the creeks again.

Training for the Tahoe Rim Trail. Good workout with the packs. Nice views of the East Bay.

Great little loop for breaking in some new hiking boots ;) Right at the start of the trail is the ascent, but once you are all the way up the views are unbeatable! Bring plenty of water, sunscreen and a hat because the entire trail is exposed, saved for a bit at the end.

Also worth noting that, since this is a wilderness area, there is livestock grazing permitted, so you are likely to run into (and definitely smell) the cows.

Great trail especially in the spring. Good winter hike. Not too many people in the off season. one of the tougher hikes in the bay and the hardest hike I ever got my wife to do...

Went with a friend. Parking spots were limited in the parking lot but it is a safe secluded spot. We completed 15 miles but had to alter a portion of this hike as we got confused on which direction to take in the Madrone trail. One of the problems is that there are additional paths or clear shortcuts emulating a trail which are not mapped and without signs. From the beginning, the Ringtail Cat trail has many shortcuts. On the other hand, the existent signs were not very clear and the paper map didn’t match the actual trails. We basically walked in circles between the Madrone and Virgil Williams trail. We tried to find the Sulphuric trail or Del Amigo trail and we just didn’t see a path. We had to go back where we came from and take the Corduroy hills trail. The Corduroy trail starts wide but then narrows to a single person lane. No shade until we reached areas that were next to cliffs and it seems that the trail narrows even more. Then we started our descend via Las Trampas to Chamise to reach the end of Bollinger Canyon Rd. Since we got lost for about 2 hours in the Madrone trying to find the way, we decided not to do the lower portion (Elderberry - Rocky ridge trail) and instead we continued into the Bollinger Creek Loop Trail. For shade, take the western part of this trail as the eastern part is in the open and the heat of summer slows one down. From here it was all uphill to Las Trampas Peak then once we reached the Madrone trail we descended until our exit point. Very few hikers in our route, we saw less than 8 people and only 2 were serious hikers the rest were people who lived around the area that came for an in and out stroll. We didn’t see much wild fauna in this hike. Couple of eagles at the peaks. There is a lot of cattle grazing from the nearby ranches.

Great hike. Went counterclockwise. Mile three is a bit technical with lots of foliage down the back of the ridge. Wish we wore long pants. Mile four is a bit grueling hiking back up and over but there are enough shady spots to catch your breath.

Probably the hardest trail I've run, but also one of the best. There are great scenic views throughout, and whichever direction you go (up Devils Hole, or up Sycamore) youre in for a great workout!

Nice trail with great view of San Francisco city and Salesforce tower :-)

Gorgeous. Amazing views, moderate effort with the hills, varied scenery—tree shaded area, rolling hills, etc.

To get this trail right, start counter clockwise, and once you are on del amigo trail, make a left on Virgil Williams trail and then a left on madrone all the way to ringtail cat trail.

Challenging, great with dogs, bring lots of water, not much shade

Close to home and dog friendly. Once you go over Ridge View Trail down Sycamore there are no people , ever. Love this hike. Not hard but you will sweat a bit. Just a good isolated hike.
