A nice mildly trafficked trail, with a couple nice view points. Ample amount of parking and easy trail access.

Wonderful views! I took my dog and it was the perfect hike for us. I would say moderate level hike- there is a good amount of elevation but so worth it! Wherever you decide to stop, there are great views! The hiking trails here can be hard to find because there are so many (at Pleasanton ridge)-but this app is perfect to guide you to your destination! Highly recommend this hike, path is smooth for most part. Would definitely do it again!

Great trail! A lot of incline and some narrow paths at times but the views made it worth it.

Inclined 80% of the trail. Really great views. A slow hike but really nice and fun. Did the whole thing with my 5 year old and he loved it too.

Great hike, wide well maintained main trail. Not a 5 star, just based on personal preference, I prefer a longer warm-up, and this hike elevates immediately.

I liked it. Good amount of incline and decent scenery. Tons of wildlife if you’re into that jazz. Hiked it in 90F and there isn’t much coverage so expect to work up a huge sweat. Good after work hike. Took us 90 mins

I loved it here! There was some overgrowth on some of the trails but it wasn’t too bad. There are some shaded areas so the sun isn’t overwhelming

Hiked 12-31-17. Overcast, but a very temperate day. I hiked the Eastside of the loop going to the water tank between post numbers 21 and 23. Then followed the west side back. Great add on for this hike. I enjoyed the olive groove, the views of pleasanton, the the quiet of the west of the ridge. Did 8.5 miles

Nice hike, especially if you live in the area and don't want to drive to more popular trails. Was super green after the rains earlier this year. And, cows!

took 1h45m to complete. good workout. spotty shade and lots of sun in may. decent amount of bugs along the way. trail is well maintained. great place for a quick hike if you live in the area. follow the path laid out, the descent is more gradual compared to the ascent

Nice little hike with great views from the top of the surrounding area. Mountain biking is listed as an activity, but bikes aren't permitted on Woodland Trail. I suggested an edit. The rest of the trails are fair game and I look forward to coming back with the bike. Today was my first time here, so I just brought the dog for a short hike. The ridge sees a lot more sun than some of the other places I've been hiking, so it was refreshing not to have to deal with as much mud from the rainy season.

Great trail. Nice incline to max elevation. One bit of advice though: PLEASE IF YOU BRING A DOG, PICK UP AFTER THEM!!! Nothing ruins a hike/walk more than stepping in some lazy ones dog crap.
