Las Trampas Regional Wilderness

Distance: 9 miles

Difficulty: Somewhat strenuous with a short section of hands-and-knees scrambling

Lead: David

Sweep: TBD

The Las Trampas and Bollinger faults combine to give this park its rugged character. On this hike, we will explore some of the rugged parts of the park and take in 360 degree views, deep canyon overlooks, open grassland, and woodland.

We’ll start by ascending the steep Chemise Trail, and then follow the Las Trampas Ridge, until we turn onto the Corduroy Hills Trail that takes us to the top of Eagle Peak. This trail involves a bit of hands and knees scrambling up and down a sometimes loose, narrow trail. We’ll take a short break at the top and enjoy the view of the canyon below us and of Mount Diablo.

After Eagle Peak, we’ll descend eastwards, and then take the Madrone Trail  to begin the long climb back onto the ridge to the highest point on the hike at Las Trampas Peak (1827 feet), where we’ll take a second break. Finally, we’ll return by the Las Trampas Ridge and Bollinger Trails.

Note that I will be ardent about keeping the group size no larger than 20 as a short section over Eagle Peak is unsuitable for a large group; we might need to split into smaller subgroups while we pass through this section. The view from Eagle Peak, however, is one of the main highlights of the hike, and you won’t want to miss it! We'll probably post the hike again next year for those who are unable to get onto the list this time around. 

Directions: Take 680 to Crow Canyon Road in San Ramon. Take Crow Canyon Road 1.3 miles west. Turn right into Bollinger Canyon Road. Parking is in 4.4 miles at the end of Bollinger Canyon Road in Las Trampas Regional Wilderness. Overflow parking is available about 1/4 mile back down Bollinger Canyon Road.

    this park was new to me and just beautiful. Wonderful vistas from the 2 peaks we hiked to. Lots of ups and downs and some scrambling...a fun morning! Thanks, David!

    Great hike! I now have calves. Oaks and chaparral in those eastern hills, but we were never in the sun for any long stretch. Nice vistas. This was definitely a good time of year for that location. Thanks David!

    Thanks all for your spirited participation in 3400 feet of elevation gain (according to my new toy)! You made a beautiful hike all the more enjoyable.

    Wow, great preserve , deserves a return visit. Loved the hilly up and down, eagle peak view, variety of terrain and Bollinger creek (minus the water of course). Thanks for planning and leading David!

    Sorry David, I am feeling sick all night. I don't think I should hike. :(

    Car pool info: If you prefer to carpool, let's meet at Tasman and Alder park&ride in Milpitas at 8 a.m. To get there from the south, take Tasman east from I-880, and then turn left on Alder; the park&ride is on your left. From 237, go south on Zanker, and then east on Tasman, and then turn right into Alder; the park&ride is on your left. Feel free to make separate carpooling arrangements if you prefer.

      I really don't know how full the parking lot gets on Saturday mornings. With the overflow area, there's room for quite a lot of cars, but it could fill up.

      January 17, 2014

    • David C.

      Note there's an error in my carpool directions. From the south, take Tasman WEST from the I-880 (and not east).

    David, I had some work commitments come up this afternoon. Won't be able to make it this weekend.

      Thanks for letting me know, Ravi. Hope to see you next time!

    It is my first event with the group. I have just joined this morning. What are the essentials which we have to have for the hike?

    January 14, 2014

    • David C.

      I'd say the bare essentials would be footwear with good grips. Prepare for the weather to be warm or cool, and bring at least a liter and a half of water (there's no drinking water on the trail or at the trailhead). Tecking poles would be helpful on the downhills, especially if you have any knee problems.

      David, I saw your comment about the "short time sometimes loose section". This is my first event and just wanted to confirm the difficulty levels. Steep is ok.

  • Glenn N

    Sorry, but Julia and I have to cancel. I've been sick and we're have things we must do in the afternoon. Too bad, we really wanted to see a new place.

  • Jean

    Sorry, David I have to cancel this. Enjoy your hike!

  • Jojo V.

    Hi, any idea how long the hike would be? I have to be home by 3pm to get ready for work. Thanks

    January 13, 2014

    • David C.

      Jojo, I pre-hiked it last week and it took me 4 hours, including 3 stops. So I'd expect 4 to 4.5 hours.

      January 14, 2014

    • Jojo V.

      I was looking forward to this hike but I am worried I will not be back on time. Hope to meet you all on the next hike.

      January 14, 2014

  • Jeanne S.

    I fell and hurt my ankle. I'm gonna see how the week goes but if it starts to fill up I'll opt out. What's the hands and knees part? Crawling over or theough.....

    January 14, 2014

    • David C.

      Its a short, steep, sometimes loose section as we approach Eagle Peak, but no scary drop offs. I think most will get up it on two limbs quite comfortably, but I know not everyone is comfortable with that kind of terrain.

    Out of Town! Have Fun!

    This is my first event with the group and looking forward to meet you all. Is anyone carpooling from San Jose? I would like to get a ride and help for the gas. Thanks

    January 10, 2014

    • David C.

      Jojo, Welcome to the Southbay Ramblers! I look forward to meeting you on the 18th. Yes, we will run a cap pool from the San Jose area. I'll post details in a couple of days.

    David, is this the same hike that we did a while ago with a small group (Jeff, Monika and Philppe?) and we took a ridiculous long time to finish?

    January 6, 2014

    • David C.

      Yes, that's the one! Philippe brought his son and his Tesla. I think Laurel was there too. I think we stopped a lot for photographs and to smell the flowers.
