I went out there today with my dog and was told they will not let you hike with a dog even on a leash. I had to leave and find another trail.

Definitely watch out for rattle snakes. 20 minutes into our hike I almost stepped on a baby one. Also the juvenile bulls were a little intimidating. Nice peaceful hike. No shade so go in spring or winter.

Drove all the way up here to find that mountain bikes are only a allowed on a small area from the north access point to the reservoir. One star for misinformation.
I did drive up to the walnut staging area from the north and rode the trails, but would only give this 2 stars for mountain biking. Go somewhere else.

Great hill by the dam. best done as a fall or winter hike.... It gets plenty hot in the summer. Near where Los Vaqueros trail intersects 10 years ago there were several nested pairs of Golden Eagles. Not sure if they're still around but it was awesome watching them fly around when I fished that corner of the lake.

Good trail.... Usually just you and the coyotes. I used to fish for trout at Los Vaqueros a lot and take a hike after i caught a quick limit. One of many trails i did here.

nice valley and lake views.

It was a Beautiful Sunday morning hike.. Windy but beautiful... right off the incline was a butt kicker

This is a very beautiful trail that is well marked and easy to follow. I hiked it in the spring, so there are many uneven areas along the black hills trail section due to cattle tracks. The views are amazing and well worth the 1000ft ascent. Bring water, a hat, and lots of sunscreen as the trail is completely exposed to the sun as it passes through grasslands. There are lots of cows here, but they are docile and avoid you as you approach. However, they may follow you for a short while after you pass. No problems!
There is a park use fee for the area of $6, cash or credit card.

Beautiful trail and fairly easy walk :)

4/22/2017 Hike
We started hiking as a family and this is only our second hike. I was afraid that this might be too difficult for novice hikers like us. It turned out easier than I thought, the uphill trek was slow going but doable. I don't recommend to people with bad knees or backs. Once you get over the hill, the views are amazing! There are some areas closed off due to erosion and at this time of the year, some parts are overgrown, but still doable. Definitely worth going to this one.

cows stopped my hike 2 miles in.

The lower trail was muddy and overgrown due to the recent rains, small areas just completely torn-up. The wind was almost unbearable to me for the first hour, but I kept going. Great uphill workout though, and a nice view of both Sierra (in far distance) and Diablo. Park entrance is $6.00.

Quite a hidden gem with some great views if you go while the hills are green. The trail starts and ends with substantial elevation changes. This not a casual stroll. Parts of the trail were overgrown with vegetation. There are lots of cows, horses, hawks and I saw a few coyotes on the trail. Also some good views of Mt. Diablo.

Liked this one because I've fished everywhere along the water it goes. There's always some waterfowl on the lake plus the Golden Eagles and a few other raptors. Awesome to watch the eagles swoop down and capture the trout. There is also a very healthy population of coyotes in the area. It's not uncommon to see them when you are away from the people.
