This trail is very muddy. There are a few spots that you will definitely have to step in water to get across. The green hills are very pretty to look at. Overall it was good family hike. I would not recommend it for kids under age 10 due to the mud & water.

It's a nice trail to spend some time on. I got over 9 miles on the trails at Round Valley.

Cool trail! Awesome stream that runs along side for 1/3 the loop. Trail was a bit rough at times due to the recent heavy rain so be careful. Perfect 2-hour walk to start the morning ;)

Wow really cool trail. There's multiple creeks that run into Marsh Creek and there all flowing! Mid February is the best time to see this park! 5 Stars!

beautiful hike. a little rough right now due to all the rain we've had. still manageable though, just wear shoes that are OK in mud.

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
