So if you like open fields, rolling hills and cows then this is a great place all of the trails are very well kept up too. Not a lot of trees or shade so make sure to bring water and sunblock. Did most of the tails in one afternoon, mostly easy to do. There was a really nice wind coming from the bay to keep me cool.

Huge open hills and grassland with hiking trails. Fantastic variety of birds and especially birds of prey.

Such a beautiful place with lots of great scenery and cute cows and amazing birds

Not much shade. The trails are nice and wide, most of them. There are cow trails too. Lots of cow poo too. Overall nice place for a walk or run.

Great exper. hiking with my family.

(Note: park is closed during red flag days)I havent even seen this place in spring and Id still call it beautiful. Mostly chaparral with native aromatics growing for that distinct California chaparral scent but only in a few places due to cow pies that are ever present and linger in the air. There are plenty of cows roaming to limit vegetation growth. I see a lot of horseback riding, mountain biking, and running. Im here nearly every weekend since mid-summer (a personal goal of mine). A good variety of hiking difficulty. What is especially neat is if you hike 10+ miles like I do, this park is adjacent to Newell Open Space in Napa County and you can hit those trails too for even more variety. The ridge trails here are awesome, always breezy and cooler than you think it would be. I cant wait to see this place when its green. Most trails are in the open and unshaded. I carry UVA/B blocking umbrella with me just in case I get overwhelmed being in the sun 4+ hours. I also keep some mace on hand in case a mountain lion sees me as lunch. There are tons of blackberry bushes (I admittedly snack on) and tree fruit I cant identify, maybe plum cherries. Benches and picnic tables are everywhere, mostly benches though. Plus theres a few PokémonGo stops and gyms to boot.

Great park! Beautiful hills, especially in the spring. Theres usually not many people there, which is a bonus.

Great for hiking. There are shaded trails and trails with great views of the surrounding areas. This park shares a border with Newell Open Space so you get twice as much space for hiking.Definitely bring water in the summer, wear sunblock, and be prepared for ticks, flies, and mosquitoes.

Excellent afternoon out walking. A little disappointed the hours are only Monday-Friday.Edit my review: I clearly need help as I cant figure out what Friday - Monday means. The park is open weekends and closed Tue-Wed-Thur.

Nice hike with great views of Solano county. You can see SF

This is a very good spot to get blackberries!!

Great trails for mountain bikes

Great place for a gravel ride. Just watch out for the cows.

Green, rolling hills; lots of cows; good views of the Bay from the western parts of the trail.

Nice place to hike. There are a lot of cows along the trails. take note that the park closes at 5:00 p.m. which seems a tad early and if you dont get out in time you may get your car locked in the park. If this happens it is a $250 fee to get your car out.

Beautiful area! Youll see cows and birds. Its very serene.Parking is $6. Make sure to bring exact change. No potable water at the park, so bring your own. The bathroom is always clean.

A little short on the shade: only one of the picnic tables has shade over it, and there are only three picnic tables!Very secure: a ranger was on site for several hours when we were there.Great for hikes and horseback riding. This beautiful canyon tucked away in the hills just a little more than a stones throw from Highway 80 is definitely worth a visit. If youre lucky, you might even see a bobcat. :-)

Ive only ever approached it from the Newell Open Space side at the top of the hill, but it looks gorgeous.

Nice. Access to long trails. Clean gravel parking lot has some picnic spaces. Clean handicap vault toilets. Have to pay to even stop in parking lot for picnic and to use the toilet.

This place has a couple of poka stops that are kind of difficult to reach other than that its not worth going to.

Beware of cows. Nice views, trail we followed wasnt that difficult but there are multiple ways. Parking fee is $6 but we parked outside of the red zone before the turnaround (there were no no parking signs there?).

Always love the local nature of the bay area

First time seeing any of this so I think its all fantastic

We do the lynch canyon run every year! We love it.

Good place to rest from the trials of the road.

Nice scenery while walking.

Hecka hecka fun

Always I had a good time

Great open space to explore. Over 10 kinds of birds, plus several water fowl. Trails of varying difficulty. Lots of baby and adult cows. Several rest and picnic areas. Nice parking area. I think parking is $5. No pets allowed.

Pretty. Ive driven by over a thousand times at all different times of the year. The hillsides are sometimes emerald green & sometimes golden retriever yellow but always picturesque & serene.

Nice hiking

Didnt go there

Its on frontage Rd going from red top Rd too hidden brrok or American cayon if you dont like those heavy traffic n high winds threw thier on the 80going west just take red top go left under 80 make second rite and take a slow safe 55mile an hour ride lynchcayon well be under 80 on your rite half way too amcan

Rode past on my bike ive never been in there but it was good

Days of availability no bueno

Perfect for family fun

Really nice place but just not a lot to do there

Nice hiking opportunity.

$6 to park here, no shade in parking area. No place to park outside and walk in. Big grassy hills surrounded by wine vineyards. No shade anywhere.

Love this open Space. Beautiful views from the top ridges!

Only quarrel is you cant take dogs.

Hawk Central, lots of resident, migrant and over wintering birds of prey in the region. Great location for hiking, walking, horse riding, wildlife and nature viewing.... look for fall and winter hikes from Larry Broderick and Solano Land Trust, we generally do one a month Sept through March.... check Solano Land Trust website for details..

It doesnt appear to be open to the public.

Lots of gates that upset the flow if youre cycling. And paying to park is always unfortunate but when the fields bloom its a beautiful place and the cattle are fun to see roaming

Good idea for family walks

Nice quiet place

Not much different from Newell Open Space but I do think Newell is slightly prettier. Dont understand why its only open Friday - Monday.

So peaceful.

Fun place

Closed. Only open Friday - Monday

Driving through, but what a beautiful sight!!

Bummed that they lock the gate at 5pm. No time for an after work hike.

Ive never been here, why us Google saying I was here

Good place to get trippy mane.
