Pena Adobe Regional Park

This is my FAVORITE place that’s close to town to get my heart pumping. I’m not a big fan of fitness gyms and prefer the outdoors, so this place suits well!
You will realize that there are many trails to go on. The one I like most is past the dog park and the parking lot. It’s next to the main driving road. The front of it is a wide gravel road and up ahead you can see a gate that you can go around. It takes me about 1.5−2 hours to get through the path. You do huff and puff and more than likely the person you bring along will temporarily hate you, but it’s totally worth it when you get to the top of the tower, you’ll feel ACCOMPLISHED!
I do recommend going there earlier in the morning before 11 am (gets real HOT quick), sunscreen (prevent skin cancer guys!), and water for hydration.
This is a great place for everyone to enjoy. Get outside and head on over to Pena Adobe :)

Nice place to come with the family and it’s very stroller friendly. There are other paths you can take if you’re looking for a better workout. The reason I’m giving it 4 stars is because you have to pay $ 3 for parking, but overall it’s a nice place to go for a walk or run.

Great place to spend a Saturday morning! I love the tower hike — a 1.5 mile moderate uphill walk to the cell tower and great views of the entire area. There are always tons of other very friendly people around and lots of cows! There’s also a great picnic area at the bottom of the hike. Parking is $ 3 in cash that you place in an envelope before entering, or you can park right outside for free.

Great place for family time. Dog park, hiking trails, horse shoes, restrooms, archery, bbq areas etc. And it actually has water in the pond again.

I love hiking here as I can find so many different routes to take. It is the most beautiful in the Spring when it is still green, but not so wet!

More pet owners here allow there spoiled brats to be bullies.
Have seen a more than a few incidents here, more than at others. :(

A nice area to walk, jog, hike, road bike, mountain bike, picnic, play Frisbee disc, horseback, enjoying the view or just relax. A safe place to be by yourself, with friends or with family. If you want to hike, there’s an inclined that will test your legs and knees but if you just want it the easy way, you have a choice. Good thing about this area is that, even though it has a lot of trails, surely you’ll never get lost. You can see the surroundings in a 360 degrees view. I really love this place from the first time I’ve tried hiking and jogging here, that was 4 years ago. There’s a lot of changes especially this time of drought like the Lagoon that once a place for lots of ducks and any kinds of birds but right now, it’s just a dried up memory of once beautiful lagoon. So sad to see it this way! And some of the trees just died and some are dying, and that’s because of this drought. But still a nice place to work your body out.

Awesome! I love hiking and taking my dog for walks and runs here. There are many ttails that you can just choose and will eventually tske you to some great viewpoints. There is a great potential for great cardio and leg workouts with the steep trails that are available.
There is a dog park available as well as frisbee golf. Its a great place to spend the day hiking and having a picnic.
Amazing view if you get to the top of the cell tower during sunset. Breathe deep and take it in :)

This place is a little bit of a drive for me and my dog but we both enjoy every time we come out this way. they have a pretty cool dog Park that allows large and small dogs to be friends. If you like you can go hiking in the mild hills or just around the little lake that is in the center. You Can feed ducks, have picnics, and just enjoy the outdoors .not a lot of tress tho .so wear sunblock ! It’s a large park and you can spend severs hours here … Good thing they have a proper bathroom !

I love going hiking here. Such beautiful views. Tons of trails. Great for all different kind of fitness levels. It’s also great for the dog too! Just make sure to come here early in the day, it gets quite hot out there. Bring some water too!

Perfect day and place to have a picnic lunch. Beautiful views and nice play area for dogs.

Nice place, beautiful lake, and natural View. Love the wild flowers and green grass in Spring Time.

Took my pup to the dog park here today! We had a great time! There was about 20 other dogs there today! So much fun! It was the first time either myself or my husband had ever been to Pena Adobe so It was kind of confusing when it came to the parking. I guess it’s kind of like the honor system when paying for parking since there really isn’t any attendant working to keep track which is unfortunate because it seemed like most people didn’t bother to grab an envelope and put in the $ 3. I don’t mind paying it since it hopefully goes into the maintenance of this gorgeous and fun park. We will definitely be back.

This park has everything you could ever want and more!
convenient access/​parking
easy to challenging hiking
gorgeous views from below and above
reservoir and creek with ducks and geese
archery range
disc golf course
toy airplane landing strip
something that looks like a miniature dirt bike course?
dog park
playground
picnic tables throughout
cows and horses
spacious
The only drawback is the sound of the conveniently-​located freeway, but it’s a small price to pay

This park is nicest during late winter and spring when everything is green. Lots of walking opportunities, hiking, ducks around, and it has an okay dog park. It costs $ 3 to enter, but parking is available outside of the gates. If it’s dusk, you’ll need to leave through the back exit as the main gate closes.

Love this place so much! Pena Adobe was the first place I’ve ever hiked at and initially sparked my interest of the outdoors. I love coming here, especially during the spring time because everything is so GREEN! But alas nothing lasts forever. As soon as summer hits everything here begins to wither away fast. Last time I went, which was almost two weeks ago, the lagoon was almost dried up! Don’t forget the sunscreen, or a jacket if you’re like me and prefer evening hikes. One thing I also need to mention is that if you are parking inside of the park, can you please contribute something to the fee. I see so many people driving through without even glancing at the toll box. I know I don’t pay the total $ 3 everytime I go, but when I’m not parking in the «no stub needed zone» I usually scrounge around my car for all the loose change I can find to atleast contribute something rather than nothing at all.

This place is my home away from home… Great for walks and hikes! Plus disc golf course, dog park, trailer parking for horses, a remote toy airplane landing strip and archery range… There’s trails that loop around the lagoon as we’ll as two towers the taller of them being about 1000 ft in elevation. On a clear day you can see sacramento and almost all the way into the bay. There’s also a hill with a cool lookout spot and there used to be a tire swing up there… If you keep walking there’s also a historic symbolic grave for the lost travelers type thing… It’s a secret gem for local photographers as we’ll. in the spring time
The hills are green green green and look like the old default Microsoft windows screen. The deer here are also fairly used to humans which can be pretty cool for a nature walk. This park also has large bbq spaces able to accommodate large events as we’ll as a large parking lot that I’ve seen used for festivals, car shows, and RVs
Be warned though… It gets really hot there in the summer and there is literally no shade… Also don’t swim in the lagoon it’s more of a goose poop pond… But if you bring bread you can have like 100 Greece around you in about a minute :)

This park is great never too packed, beautiful view, haves a dog park portion and swings for the kids. Overall great place for a hike.

Peña Adobe is a beautiful outdoor area, unique and full of options for those who love the outdoors. It’s grassy hills are great for, hikes, walks, jogs, dog owners to take their pets and a dog park, a full disk golf course and a beautiful lagoon. It’s full of wildlife such as deer, rabbits, squirrels and chipmunks, birds of many kind such as ducks, geese, egrets, vultures and birds of prey. It is irreplaceable open hills for animals to live and people to enjoy nature. I sincerely hope that the city of Vacaville will always make this area a priority and not develop on it, as there have been rumors of them doing so.

Great place to get out local and enjoy nature. Never know what your’re gonna see. Plenty of trails to explore. Favorite place to run in the area.

Most people say this park is a nice place for a walk, but I found it to be a nice place for a hike too. The hills surrounding the lagoon all have trails that are short but challenging based on the ones you pick. You can make it what you want as they all lead to another trail on another hill. There is a cow pasture right on the edge of one trail too. You could see wild turkey, deer, turkey vultures flying close to your head and turtles in the creek. For me it’s what I want from nature – a good hike and plenty of visual stimulation.

This is the biggest park in the area. If your an avid runner or biker you will not be disappointed. So if you want to get in shape or just enjoy some nice scenery I recommend you check this park out. Oh there’s also a dog park for you dog lovers out there.

$ 3.00 for an awesome outdoor adventure? Yes please.
Pena Adobe Park is going to be on your right as you follow your GPS into the park. Think «bear right» as you look around wondering where to go. I happened to pull into the little fenced area by accident, interrupting a rather private group picnic going on. You’ll want to look for the short little stand in the middle of two lanes — that’s where you’ll be writing out your own admission ticket and dropping off your $ 3.00. Bring a pen!
I made the mistake of parking in the first lot I saw. Keep driving! There is a closer lot at the bottom of the trail that is closer to the water fountains and, if you are bringing a pet, you don’t have to struggle walking at the edge of the lake with your pet if they have a slight bird obsession.
The hike is a nice, easy incline. Hikers of all ages and skill levels were out on the day I went. Some marathon junkies sped past me huffing and jogging up the hill and I passed some touristy people oogling and taking selfies with the gold fields behind them.
My main complaint is the horse people. Lots and lots of people trail riding. This would be fine if they didn’t convene at the bottom of the trail, taking up all of the trail space and making going in difficult. My dogs don’t care about horses, but some horses care about dogs, and despite the fact that we looped around three times before entering the trail to give them plenty of, «we’ve coming, move along» they still stood there. They also tend to hoard the trails, riding side by side and moving into single file for other park guests. AND… their are huge piles of horse poop everywhere. No dog poop to be found and tons and tons of horse poop. Makes for a bit of a miserable time when you’re having to dodge huge road patties the whole way up. Shouldn’t they at least have to shovel it off the trail? Luckily they seem to quit about ²⁄₃ of the way up, probably because the trail becomes paved and it’s not safe for the horses.
All in all, fun hike, cool trail, lots to explore and can’t wait to go back!

Definitely an outstanding park to play in or just chill at. Great area around the lagoon for a run like many have already pointed out. Or maybe just a nice leisure bike ride. I heard there’s also a nice dog park on the other side of the lagoon (haven’t gone there though). There’s a large gazebo like area to hold a large BBQ picnic where you can sit and be shaded from the heat of the sun (I’ve attended a work BBQ as well as a wedding held here at this spot!). There’s a little pond nearby where you can take nice photos as well as a huge grassy field where you can set up a badminton or volleyball net or throw around a frisbee or football or kick around a soccer ball. Bathrooms are just a few yards away in the parking lot, equipped with working sinks, toilet paper and paper towels! No mirror though.
My only complaint is there are so many (not only flies but) yellow jacket bees!!!
