Nice trail... You have to go through a gate at the back of Round Valley. I came across an old homestead back there as well.

Dry and hot... Best done as a winter trail.

I went with a friend today. It was a beautiful hike. We walked through the herd of cows (no joke) and saw hawks, flowers coming out of know where and the views where breathtaking! Go and enjoy ...

Simply Amazing...will for sure be back!

It’s a good little hike with the family or dog. There’s not much shade, but the views of the rolling hills are good.

Backpacking Day 3 of 3 Mt. Diablo Range. Morgan Backpack Camp (Morgan Territory) to Round Valley Equestrian Center (Marsh Creek).

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.

great hike in spring with all the wild flowers, unless you have allergies! Beautiful views of the livermore valley year around.

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.

The first part of the trail is all uphill so stay to the right when the trail forks, otherwise you can go down by the reservoir and hike back along the beach to the parking lot (like we did).

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

This is a fantastic trail in which you walk through open grasslands and oak woods and you are always surrounded by the forest covered hills. You can also access the park's group camping area on this trail as well as the out and back Fox Tail Trail. The majority of the elevation is right at the start and then (because it is a loop) right at the end. Plenty of Brush Rabbits and other wildlife to spot. Also some turn of the century farming equipment here and there since this was once a working ranch/farm.

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.

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.

This trail is actually in the park named Round Valley Regional Preserve. However, Round Valley is next door to Los Vaqueros Reservoir, which is spelled incorrectly as well.

Round Valley Regional Preserve address is 19450 Marsh Creek Rd, Brentwood, CA

I hiked the area a lot with a few different people but never saw another person here in the winter or fall. Definitely the time to do it. I was hardly ever here in the summer.

I use to fish and hike out here quite a bit a couple of years after they opened it. The trails are uneventful but a pretty good hiking and fishing place in the fall and winter months.
