Hours: sunrise to sunset

Fantastic options as you traverse the main trail. Lofty vistas make hiking up a ridge worth the effort. The trail is good for most... it can be a tad steep in some places, so wear proper footwear.
Don’t forget to pay... 6-month pass (affordable) and parking fee.

One of my favorite local spots.

Hiking here various in difficulties. Some spots are paved and flat, while others become rocky and heavily inclined. The trailheads aren't really marked well, but do point you in the direction of land marks, ie: Pond, Lake, Caves.

What I love about this hike is the varying terrain and views, You'll start out deep in the forested areas, eventually getting views of the cliffs and more rural areas of Fairfield. Evntually stumbling across a small pond and then a nice lake filled with an abundance of wildlife.
It's not uncommon to see Herons, Ducks, Chipmunks, Fence Lizards, Turtles, and Bullfrogs in and around the pond.

Nice trail, not terribly difficult on a very warm, sunny day. There was a fair amount of shade and decent views of Green Valley. Following the trail markers was somewhat challenging (and my GPS went a bit wonky), but it didn't take away from the enjoyment. Also, $3/person for day permit.

It’s been three weeks, and I’ve finally recovered and calmed down enough to write a review without profanity. First, this hike can only be described as “Easy” if you’re about 6 feet tall. There were at least three spots climbing up the hill that required me to use my hands because they were so steep and little to no footholds. Also because I went under the false assumption this would be an easy trail hike I was not prepared with enough water for my dogs. They finished off the 16oz before we even made it to the area by the cave. By the way this is NOT a dog friendly trail. After surviving the trek over the hill I was looking forward to the level walk around the small lake. Frustratingly blocked off by a barbed wire fence and posted signs that no dogs are allowed, I didn’t think we’d survive finding another way to pick up the trail on the other side, and I wasn’t willing to risk another mile or two. So I carefully pushed my dogs under the barbed wire fence to get into the area then out. Finally coming down the last slope to the main entrance I slipped on a patch of loose dirt and landed on my knee. I literally left behind a (quarter) pound of flesh. Also noteworthy there’s an entry fee for people and dogs. The payment machine accepts cash and credit cards. One star for the GPS mapping working quite well. The only good thing was I didn’t get too lost.

Perfect moderate trail, a bit of everything

Unexpected beautiful landscape. The cows graze land; so be mindful since they’re not behind a fence.

Great Trail!

Great trails! You can pick trails from easy to moderate. Some of the trails could be better marked. I especially enjoyed hiking amongst the cows!

I love walking at this park.

Nice place for a quick hike. Not a lot of elevation gain if that’s what you’re looking for. Lots of mountain bikers so be careful on some of the trails. Would definitely recommend for a quick hike or just a nature walk.

It is very nice train

Even though the lack of signage made it confusing the views were gorgeous and the trail was challenging but not overly so in some areas. I'll definitely go back

Nice place to hike bc most trails loop back to where they started. I hiked this route and decided to also do the Upper Tilly area to add another 1.75 miles or so. The only wildlife I saw were squirrels and blue jays. And plenty of mountain bikers.

Wow! This is my new favorite spot to run. It has everything I need: amazing views, alternate routes, hills and spots for scrambling, hidden gems...
I could run here again and again and take a different system of trails each time. Although I could appreciate some people being frustrated by confusing signage, I'm completely open to making impulsive decisions in the moment.
Other: Quite a few friendly mountain bikers out. This place probably gets slippery in spots during a good rain. Feels secluded but you can hear the road and buzzing power lines. Surprised by lots of garbage and graffiti up at the cave.
Will def be back! Worth $3 for sure.

We had a hard time finding the trail as described here. We had to ask a ranger for help and she didn't know where this map was for as the only "green valley" at the park is a small section of trail. she gave us a new route and we ended up on rock garden trail with a short trip up tower trail and then back on chemise loop and lower quarry trail. It was not an "easy" hike but it was fun.

trails are not as well marked as exoected. plus green Valley trail is not named the same as on the trailheads but followed the map tool on the app and found our way. nice well maintained trail fir both my 13 year old daughter and dog. took a little under 2 hours to complete but that included time for exploring cave and taking in the views. nice hidden gem and offered views that were not expected. I plan to come back and try one of the other longer more difficult trails.

Hard to follow. There are so many options for trails. We ended up with a 3.44 mi run. There are several rocky places, but it still made for a pretty good run.

Really cool park on a hill side with great views! Rolling hills but be aware that a lot of the trails cross cross often so it can get a little confusing if you're trying to wing it. I tried to stick to the map on this app but must have deviated because my run came out to 5.5 miles. Some places are pretty rocky so watch your ankles. Some shady spots but a lot of sun exposure. Cool pond and lake great for wildlife viewing.

We went as a family to this trail. It was a lot of fun. the kids enjoyed the baby frogs around the pond. it is a huge park, so be careful not to get lost. if it wasn't for this app it would have been hard to find our way out!

A hidden urban gem. A good meeting place between Bay Area and Sacramento. Green and lots of flowers...and a flock of sheep!

The trail head is right after the residential neighborhood. You won't see it if your not looking for it. Luckily the trail is moderately used & there were cars parked on the outside of the trail start & it helped to look where people are heading. It starts with a slight clime up. Be prepared to go slow w/all the traffic the trail gets. You can stay on this short trail or you can go exploring as their are other trails in the same park you can go out that mingle in with this specific trail. No opportunity to let the dog off leash to explore. Too many people. Otherwise, great park and some great views at the top. This can be a loop trail.

Lots of hidden surprises as you go! Friendly people, clean park, and sheep were extra added bonus! Easy trails all around!!

Favorite spot and must see is view above the lake!!

Surprisingly lovely! Starts out where you can see the valley and the highway but you're quickly in a secluded area with lots of well maintained trails. Elevation gain is minimal - 500 ft ish.

Great hike to get you back in the groove.

Went here on Sunday (1/1), it was really nice and easy hike. It is not challenging at all but is very pretty. We saw lots of birds like turkey vultures, red tail hawks, and others.
The only thing we didn't like about this hike is that the signs are super confusing. It points one way and the other sign points the opposite way. The map in the begin is helpful with getting around.
Another thing is that the parking is $3, there are a few spots out on the road that are free.

Beautiful view! This place has several trails from easy to hard.

We had a pleasant 7-mile (3.5 hour) hike in Green Valley Trail today. We started at the intersection of Vintage Valley Drive and Dynasty Drive in Fairfield (Green Valley). We hiked along the pedestrian walkway past Green Valley Creek up to the park's southern entrance. We turned left onto the Black Oak Trail, left on Middle Mystic Trail, left on Twisted Tree Loop Trail, continued Junction trail to Root Trail, and left on Cliff View Trail. We continued onto Outer Loop Trail, right on Rock Garden Trail, we looped around the lake and took the Bay Area Ridge Trail to the Green Valley Trail for the return back.
