Great hike. Good for medium or heavy cardio. Needs a little path clearing but still a great viewpoint

Beautiful hike, especially during spring time. Lots of wildflowers along the path.

A great trail, especially running up the first hill. Once you get to the top you get a beautiful scenery.

One of our favorite hikes, We add the Devils hole loop adding 1.8 miles. Once you go over the ridge into Devils hole loop you are completely alone. No city noise, no other hikers - ever, no mountain bikes. Just Retail Hawks, Turkeys, Stellars Jays and views of Castro Valley, Oakland airport, and San Pablo Reservoir Dam. It is single track with switchbacks heading down Sycamore Trail, Fun. The climb out of Devils hole is straight up, a butt kicker. This is one of our go-to hikes. Then come down Elderberry is mostly under canopy so it's kinda doable on a warm day. Just under 8 miles.

Great walk. The ridge line was fantastic. Took us about 2 hours at a nice clip.

Good work out! Variety of views with wild flowers, stream, and fossil rocks.

a great hike with excellent views. We picked a nice cool day with white clouds for a backdrop. Will definitely hike again!

We hiked the loop in reverse starting at Madrone Trail and I think it was even better. Good challenging day hike for semi beginner hikers.

Staging lot to the gate up the hill is a tuff climb, 1 mile. Once at gate, Ridge Trail and Cuesta Trail off to left whines further up hill. Once on ridge beautiful view of San Francisco to west, Mt Diablo to east, Concord and river in back ground to the north, and then Tri-Valley off in distance to the south. Was pretty windy up their but in Feb. clear day and hills all green.

Steep incline to start for roughly a mile but evens out near the top. Beautiful view of Diablo and lots of bird sightings. Mind the cows

Great trail. Couple of things to note: cows (to avoid) in parts of the trail; very strong winds sometimes in top. Not for beginners.

Very pleasant hike. It’s not too hard I would rate it as moderate.

It's like running on pillows right now

Great reward for the hike up - amazing views

Beautiful views from the summit. Be careful not to take Cuesta trail cutoff and no bueno in winter. Massive mud track.

I ran this one. Beautiful views, very challenging, especially when you get to the Corduroy Hills Trail. This is for someone who is looking for a challenge and is not for the faint hearted.

Wonderful experience. One among the easier hikes I would say, nonetheless the views are amazing. No mud when we hiked today - seeing the trail it’s very clear why people have complained so - a drizzle and it could all turn muddy in no time.

Highly recommended - if it hasn’t rained recently.

Beautiful and a bit hard but totally worth!

Beautiful hike

Tough uphill to start, but great trail with some optional routes. Beautiful views of the San Ramon Valley and Mt. Diablo. My wife loved it!

Beautiful hike on a clear day! It was fun to see Diablo get bigger and bigger as we climbed. Also cool to be above the hawks!

This is a pretty tough hike, as there's two big gains, as previously mentioned. I think this is best done in Fall/Winter as there's really no cover. Also, the track on here doesn't seem to take you to a Peak. I'll need to try this again and see if I can find the actual path to what I think is the Peak but still a nice hike. I didn't see anyone once we entered the watershed either. I plan on trying this again when it cools down.

My second attempt of this trail was successful. Went in the afternoon in a counter-clockwise direction. Chamise, offers some good views of the canyon, but is exposed and is all elevation gain, lots of lizards to keep you on your toes. Take a break at the junction of Mahogany to cool off and catch your breath. Mahogany(mostly tree cover) saw a doe & fawn. Trapline(partially exposed especially toward the top, more good views) it starts with stairs. Lol. The end of Trapline you have to climb over a gate, preventing mtn. bikes and horses from using this trail. Yay! You made it to the ridge, Sulphur Springs stop at the bench in the grove near the beginning of the trail, only man-made seat to sit on and ponder your existence. The trail goes down, and then up has a nice grove at the bottom at the dry creek, Del Amigo a wide trail is pretty much all down, only place I slipped on hike. Good views of Danville and Mt. Diablo. Virgil Williams is shaded and pretty flat and a nice break from all that downhill, Madrone is a wide trail that goes easy up to the dry creek and then easy down, good views also on this part. Once you hit the junction of the Las Trampas/Mt. Diablo trail it is all moderate uphill. Madrone was the only trail I met people(A guy with a dog, another guy with a dog, a Mtn. Biker, and another hiker who turned around at Corduroy Hills trailhead). I took a snack break at the junction for Corduroy Hills, Corduroy Hills is a difficult/hard trail once you start up the single track, which by the way the trail marker is off from the main trail, and can be a little confusing, but yes start hiking the single track uphill on the right, note a part of the hike is somewhat treacherous, at one point the trail has almost fallen down the cliff and it is a steep drop-off. The highlight for me was Eagle Point, google the images to see. I sat there for some time appreciating this formation. It felt like bouldering heading down the trail from Eagle Peak. I want to go back to Eagle Peak on another hike(Bollinger Creek Loop). I liked it that much. Expect to climb up some tall steps. After hiking for what seemed like an eternity. You finally stumble onto the Las Trampas Ridge Trail. this was an easy ridge hike, Chemise is now all downhill with tons of scat for your viewing enjoyment.

There is no water on this hike. My first attempt was an 8am start time in the Summer and it was already a hot hike. Not for the faint of heart with the heat and elevation change. There is a nice grove with a bench hidden in it, on Sulphur Springs at the junction of Las Trampas Ridge(aka Calaveras Ridge Trail) We got to the junction of Virgil Williams and Madrone, but had to bail since one persons boot fell apart. We went to the Eugene O'Neil Nat'l Historic Park, which has water fountains, if needing to replenish. We hiked out through the neighborhood and got a ride back to the car.

Family and I started at around 10 AM in early September - sunny/clear skies/ 70-85°F. Parked at the Staging Area and picked up a trail map from a case on the far side of the lavatories.
Bring a hat, sunscreen, 1L+ water/person, and shoes with good traction. Beware of flies and poison oak. No wildflowers in late summer but plenty of hawks, lizards, cows, and the occasional deer. Start early to avoid the heat.

We hiked the route clockwise, starting from the Staging Area and Bollinger Creek Loop Trail (we took the right fork through the trees although either is fine) and continued right onto Las Trampas Ridge Trail, then left onto Corduroy Hills. We took a right onto Madrone Trail, left onto Virgin Williams, then left onto Madrone again, continuing past the pond and Eugene O'Neill Historic Site on the second leg of Madrone - both were pretty fun milestones, would recommend.
Madrone continues onto Del Amigo, and from there there are many routes to slightly shorten or lengthen your route back to the trailhead. We followed the hiking path onto Sulphur Springs, then Trapline, Mahogany, and Chamise. We ended at the Chamise trailhead and walked the short distance back to the Staging Area.

The first half of the hike was an easy/moderate, with lots of shade in the woods, some slopes, and both rocky and dirt terrain. I'd say the best views are during this part of the hike. There are a couple short but steep stretches between Bollinger Creek and Eagle Peak to keep things interesting. Since we hiked the loop clockwise, Corduroy Hills was mostly downhill for us. It looked pretty strenuous in the other direction - a continuous incline with virtually no tree cover. Something to try on a cooler day.
This trail was virtually downhill until Del Amigo. From there, expect uphill and a switchbacks until Sulphur Springs. There is shade and tree cover here - by now the afternoon sun was in full force. Back to easy/moderate along Trapline-Mahogany; a nice cooldown back to the trailhead.

The trail was lightly trafficked - we saw a few hikers, dogs, and the occasional biker, but were alone for most of the route. Great variety of dirt and rocky terrain, up/downhill slopes, and forest/open landscapes. Lovely views of Mt. Diablo, Danville, and the surrounding areas. Would love to come back and try the loop counterclockwise or one of the variations. No extensive experience necessary, just water and stamina.

Another option to get to wonderful Corduroy Hill is to go the opposite direction. Start from the Bollinger trailhead, head up one of the Bollinger loop legs (the one on the left nearest the trees will be full of cows on a sunny day), and meet up with the Las Trampas Ridge Trail. A left will take you past Redwood Peak, a fine little scenic spur, and afterwards send you circling around hills in a remote park of the park with fantastic views of not only obscure slices of Las Trampas, but, inevitably, Mt. Diablo looming over it all. A right on the Madrone trail takes you down into a ravine in which there was still a significant trickle of water in the creekbed in late August! Very cool. The Corduroy Hills trail will appear on your right after you emerge from the forest, and the real climbing and clambering begins. It's a tough, steep route, but incredibly rewarding. Something like 7.2 miles in all, likely a slightly higher total elevation than the 2214 total of the other route.

We went 2 couples, each with a baby. We took them on baby carriers. The beginning of the hike you ascend very quickly so it can be a challenge, but shortly after ending the paved path the ascent stops and its pretty much little ups and downs from there. It was very windy on top but not cold. Amazing views. Highly recommend.
