“Great place to hike!”
4 of 5 stars Reviewed February 21, 2013

Nice local place to get out and hike! Not a lot of shade so beware in summer. Also in summer you have to look out for rattle snakes. I have seen several here and they are big. I love it in the spring and fall.

“A terrific place to hike close to Brentwood.”
4 of 5 stars Reviewed May 30, 2012

Round Valley offers several trails with varied diffiulty. It's a pretty area, some open, some in the trees. We have had to navigate around the grazing cows occasionally but they just ignored us.

“Secret gem in the Brentwood Marsh Creek area”
4 of 5 stars Reviewed April 13, 2012

Round Valley Regional preserve is a hidden gem. Cross over a bridge with a creek filled with water after the rains, and dry in the fall, filled with boxing turtles and wildlife. After crossing the bridge head left to meander along the creek, or go straight crossing the cattleguard gate and enter a preserve filled with trails that either head up the mountain or follow the valley all the way to Los Vaqueros watershed. Cows roam through the preserve, and you might see coyotes, ground squirrels, tarantulas in the fall, craggy rocks, ponds up in the hills, etc. When you ascend to the top of the Hardy Canyon trail in one direction you can see stunning views of Mount Diablo, and then turn around and see all the way east to the snow-capped Sierras. During hot days make sure to bring plenty of water. The flat Miwok trail is good for even inexperienced hikers. The Hardy Canyon Trail can be strenuous, straight up hill with multiple switchbacks and a few steep ascents. Leave about 2 hours to do the Miwok to Hardy Canyon loop back to the carpark.
