Chamise Trail and Bollinger Creek Loop Trail

Nice hiking out there! It’s nice to see Fresh green hills.

nice people.lots of cows and cow pies. ran across a grumpy cow on the trail and he tries to charge me and my dog. we were fine. no issues

Beautiful hike. A few steep inclines.

It's a nice trail with a nice view! But be warned, there are some steep hills that you have to climb up! But it's definitely doable and after you finish that uphill, you'll be rewarded with a view :) Happy hiking!

Can’t believe this was only 3 miles! It took me an hour and I really enjoyed it. Great views, a nice steep ascent that made me feel I was getting a workout. Some parts are pretty narrow and could do with clearing but generally well marked. Nice shaded parts, pretty trees, crossed a dry creek.

Did the hike counter-clockwise. All uphill to Las Trampas Ridge on Chemise(pace yourself for enjoyment) watched the birds of prey soar up an up. The trail marker points for Las Tramps to the South, but you want to go North don't worry the trail is really North too. Take a detour and hike out to Eagle Peak(Zen and good views) on Corduroy Hill its down and up but only 0.4 miles out of the way round-trip. Take the Bollinger Loop trail off Las Trampas which is a single track, but looks much better than the big boring fire-road. On the last leg of the hike on Bollinger Creek Loop trail take the western side for more cover from the sun as you walk in and out through groves(note follow the warning post pointing you upwards or you will be walking on a washed out trail and have to take a mini leap of faith and climb over a fallen tree or two), expect cows on the last part of the trail.

One of Las Trampas easier hikes but even that is tougher than most hikes in the bay.....very enjoyable.

I really enjoyed this trail! It's quite a climb though, so those less experienced should be a bit more careful. There's a few narrower spots as well. The views are beautiful! Great for dogs too. The reviewer who wrote about the aggressive cow was not kidding. There was a heard of cows who saw my small dog and started walking towards us rather aggressively. Everything turned out fine, but be weary if you're walking with dogs or running.

Great variety of inclines and declines, good mix of shade and sun, gorgeous views of multiple valleys. Wear long pants, sharp plants and some poison oak.

It was great! It had some easy parts along with a few moderately challenging hills. We encountered a rattlesnake so just be cautious. The rattlesnake didn't rattle so it wasn't too scary:) great and rewarding hike!

I hiked the Bollinger Creek Loop Trail late morning today. Starting at the Bollinger Creek Loop Trail. I continued onto the Las Trampas Ridge Trail, then turned left onto the Calaveras Ridge Trail, went down at the Trapline Trail and Mahogany Trail and back to the parking lot. Total distance was 3.3 miles with 719 feet elevation. The few parts of trail were muddy but it was manageable. It was a great hike and I totally enjoyed.

Good trail, did it around noon, partially shaded. Nice views. You can peek at Mt Diablo from few spots.

Nice trail with some hills and views. I did this one and Rocky Ridge Loop back to back in mid December. The trail was muddy at parts as it had rained two days before I went hiking here.

fine

It was nice. There are several trails here. We got turned around because of the cows but found a nice shady trail. Beautiful.

Great hike with beautiful views on a fall evening.

Good hike. Nice views of SF and the bay. The trails are in good shape. Very nice place.

Great hike and nice views.

This was the first park that got me into hiking. I went to the elderberry to rocky ridge trail and it's really nice up there. windy yes but to scale the hills was worth the sight. the elderberry has a lot of tree then dry dirt then trees . make sure to have a flash light if it's getting dark. but the rocky ridge trail is my all time favorite. take me about 2hrs to complete if I wasn't stopping and sitting on the rocks looking out in the view. you'll see all the 3 bridges( Dumbarton, San Mateo bridge, and bay bridge) and then on the other side you'll see some of the windmills from the trivalley.

Recommend on a nice cool day, take lots of water. Snakes roam the streets at times. Very windy in top. Steep incline, scene changes as you walk from, trees with miss to plain view of mountain top. Overall a good hike on the rim. Bay leaf trees on the picnic area.

Beautiful. This Wilderness is exactly the place I want to be to escape suburbia. In all seasons, there's magic here: wide open vistas, Mt. Diablo to the East, mesmerizing green hills, pops of CA poppies, running creeks, grazing cattle, and the best of all: the magical mighty oak trees.

On any Ridge trail (Las Trampas, Calaveras, Rocky) you will be in awe of the view. Of course, you'll have to work for it-- but that's the fun! There's many choices to enter this Wilderness: At the end of Bollinger Canyon Rd in San Ramon, OR off Remington Loop in Danville, OR at the end of Camille OR Hemme in Alamo. Each will provide a different experience! Grab a map and explore-- I promise you won't be disappointed.

Living in Danville I can be submerged in this beauty in just 10 minutes. For proximity, seasonal beauty and multitude of trails, this is my favorite hiking area.

There are all sorts of trails you can hit at this park. One is along the creek that flows in Winter and Spring and is fairly shady. I like to pick my Bay Leaves from all the Bay Laurel trees along this trail. From the parking lot, go through the green cattle gate on the far right of the lot and make an immediate right turn up the hill and through another cattle gate.

There is also a killer paved trail that is a real climb! Once you get at the top, there are other trail options on dirt paths. There's picnic areas here too along with good views.

To get to the parking lot, take Bollinger Canyon Road all the way till it ends,

Nice workout, front right side of loop is simi-intense! Dusty trial in some parts don't go during peak heat.

Be prepared for hills! Dogs are allowed off leash though deer are plentiful and the area is also a grazing land so cows are around as well.
