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.
Spent a few hours doing a big loop through the park. It wasn't spectacular I terms of views, especially with construction of a housing development that goes right up to the park's fenceline. Hot, grassy, hilly. There's a cave you can visit, but it's sad if you climb up to it, covered in graffiti and full of broken glass, bottles, and other detritus. I also found the multitude of short, crisscrossing trails poorly signed, but the park isn't big enough to truly get lost in.
Good afternoon hike! We're beginners; it took us about an hour to get to the cave (via the lower quarry trail) and back. The lower trail was easy but heading up the to cave I'd recommend good shoes. I had flip flops on and it was a little dirty/difficult. We attempted to go all the way to the cave, if you have children or dogs, I wouldn't recommend as it's steep and has some loose gravel. The lower trail didn't have as many nice views as the hike up to the cave. However, it was very shady and leisurely. There are a few other trails to explore here! Also, be prepared to park on the street or pay for parking.
A beautiful area for sure. Not actually a loop trail but a multitude of shorter trails criss crossing and intertwining.
Looks like an amazing mountain bike area(was wishing I had mine)
The only downside was that the humans don't take out what they bring in. I saw literally dozens of plastic water bottles throw along the trails and in bushes and that sucks. Other trash as well.
But still some beautiful views to take in.
This was a great weekend hike! There are plenty of trail options so you can go farther or make your hike short. The scenery was beautiful! In the beginning it did seem pretty crowded, however there are many splits in the trail so once we got farther into the hike we barely saw anyone. It is definitely dog friendly, dogs $1, and $3 per person and you keep the ticket with you on your hike. We will definitely be doing this one again!
Did this trail with a large group. Overall it's a nice area great views of the valley and the vineyards on the backside of the hills. Be careful of the mountain bikers who also share the trails. Great for a training hike (we made a figure 8 that consisted of about 7.5 miles), not great for a challenge unless you're just starting out as a hiker.
