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.

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).

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

BIKES PROHIBITED

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.

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.

Beautiful trail and fairly easy walk :)

cows stopped my hike 2 miles in.

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

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.
