Contra Loma Regional Park & Swim Lagoon

I only visit to fish, but that’s plenty good. Regularly stocked with trout of good eating size, I rarely get shut out when I’m tossing in a line here. The trout bite great on Powerbait with a little garlic scent added. Everybody who fishes here knows the best spot, so I won’t belabor the point, but I’ve caught fish from just about every spot I’ve fished.

What a fantastic cool little place to go swimming! It’s super cheap which makes it an excellent family outing location for bbq and fun!
Can’t wait for summer to come again so I can come here. :)

The best I go there every summer sometimes to swim and sometimes just to chill in the park and you can fish but u need a permit and there’s some trails u can walk through.

Great place to bring the family! Very relaxing. Lots of shade, clean, and great views. You almost forget you’re in Antioch. Life guards are always on duty and the swim area is sectioned off so the big kids and little ones are separate. If the kids want to go in the deepest end they have to take a swim test, which is a great idea.
If you don’t want to swim and would rather have a picnic or bbq, then this is the perfect place. We will definitely be returning.

thanks to the first aid and regional park personell they were very professional and tended to my wifes spider bite

I love hiking here. There is so much wild life and after a few good rains the hills are green and beautiful. There are plenty of steep hills for the more advanced hikers and nice flat trails for those who don’t wanna break a sweat.

This park offered a nice escape into nature without having to go on a full blown hike.
It featured a meandering trail that circled an 80-​acre lake. We enjoyed the views and saw people fishing on the lake, jogging/​walking/​biking the trail, strolling babies, walking their dogs, and feeding the geese.
We walked the trails, observed a herd of cows and threw boomerangs. I was SO thankful that we didn’t encounter any ticks or rattlesnakes. Both make their home in this park so The East Bay Regional Park District shared some tips for avoiding the danger:
Ticks
– Don’t lean on or rest against the oak trees.
– Keep your pets on a leash so they stay on the trail.
– Stay on the trails yourself.
– Tuck your pants into your socks and your shirt into your pants.
Rattlesnakes
– Never put your hands or your feet where you can’t see.
– Stay on the trail. (The drought turned the high grasses bordering the trail yellow, making it even easier for rattlers to hide almost in plain sight.)
– If you insist on leaving the trail, at least make sure you’re wearing sturdy high boots.
A good part of the trail is in full sun. If for some reason you forget to bring your own water, you can buy bottled water at the vending machine at the pool house.
The 30×70′ public swimming pool was the jewel of this park. It looked like something out of a country club or resort instead of a place open to all local residents. The edge of the aqua blue pool touched the brim of the lake and there were rolling hills in the background.
It was so nice that the geese were swimming in it instead of in the lake. It’s not free but at $ 3.50 (or less) it’s a good value for the money. Check pricing and other details here:

I loved this park. If I leaved nearby I would be there every week.

Really enjoy coming here for a nice walk or run. The only down fall is they hAve rattle snakes. I have yet to see one.

Ok well the park is really nice and pretty. I drove about 45 min out here because other Unilocalers said they bring their dogs here to swim. At the gate I paid 5 bucks for parking, and 2 bucks for the dog. Once I got down to the water there were numerous signs that said there was no swimming for dogs and people, and you would be cited. It’s a nice place but I would not have driven out here and paid if I knew my dog could not swim. It’s not the parks fault… It’s Unilocalers who aren’t accurate.

I enjoy walking the trails in the park because they challenge me. Each trail has a different view of the park and it is breath taking. If one is going to walk, do it in the mornings because the afternoons are quite warm.

This is an awesome place. The view in winter is green and beautiful. In a foggy day, the view is even better. I am not sure how the view turns out in summer when everything turns to yellow. Let’s wait and see.

This park is one of Antioch’s finest. I’ve come here to take a stroll around the lake, and I’m sure it’s a great place to run a few laps. It’s beautiful in January and early spring. I haven’t used any of its other amenities like the baseball field or the swim lagoon, but they all look in tip-​top shape. I always park on the entrance right off of James Donlon blvd. I’ve heard that you have to pay for parking, but I’ve never had to in that area.
I do recommend this park to anyone who wants to start being active!

Really pretty park and lagoon. Lots of bug/​midges though in late summer/​early fall.
Hiking trails can be pretty exposed too and it can get really hot here. My son and I did the Brazen Drag n Fly 5K here. Even at 8:30 in the morning, the sun was out and it was pretty warm. Be sure to wear lots of sunscreen and bring lots of water if you are going for extended hikes. This park connects into the Black Diamond Regional Preserve so you can go a long ways on the trails.
Lagoon was full of birds. Very nice.

This is my place to relax, take a nice walk and not be annoyed with the sound of cars or too many people. I keep my path to going around the lake, but the hills have many trails. Dogs and bikes are both permitted, so it’s a nice place to see many different people getting some exercise and outside time. A little treat in Antioch.

This place is great. I’ve only lived in the east bay for about 7 years, but I’ve even coming to Contra Loma since wayyy before it was a pool (probably around 15 years or so) because I’ve had family out this way. The pool is a great place to catch some sun and just hang out for the day with family. You can bring in food and coolers (as long as it isn’t glass) in the area or you can take up space at one of the picnic tables. Plus, there’s a few trails that you can hike (they’re on my to-​do list!) so there’s plenty to do.

Beautiful lake. You can enjoy a walk around the lake, camp, fish, bbq and swim here. The swim lagoon resemble a beach because it is filled with sand, fun for the kids to build sand castles.
They have numerous bbq pits all around the lake, so you can grill some burgers and enjoy the view!
Everybody around the lake is friendly, for the most part lol…
They say they plant fish here, but all I’ve ever seen were fish the size of my finger and never anybody catching anything.
Awesome lake for the family to have a day out doors.

For a public pool this pool is clean. I would prefer it not have geese in the swimming area, but how can you make them leave?
I didn’t realize that this was a beach-​style swimming pool, so be aware that you will get dirt, grass, and sand all over you and in your food (if you bring a picnic). However, most kids will love this place! Kids can play in the sand and really enjoy themselves.
This us a great family picnic area as well, and the picnic area us open all year!

Love this little place! We came here a lot last summer (2013), and plan to do the same this summer.
It’s pretty safe, and most children are required to perform a swim test in order to go into the deep end.
They also periodically empty the pool of all swimmers to allow adults a few minutes alone in the water without splashing kiddos :)
Parking is plentiful, although one evening my friend had her van broken into (Macy’s bags were in plain sight) so beware of leaving anything appearing of value in open view.

It’s a nice place to:
Take a short walk.
Take a long walk.
Take a short hike.
Take a long hike.
Have a picnic.
Do some fishing.
Swim when it’s open.
Ride a horse.
Have a party when the weather is nice.
Clear your mind and be with your thoughts.
There is plenty of parking and if you are looking to save a couple of dollars, you can park up the street from the entrance or on the other side of the reservoir, there’s a parking lot off of Old Ranch Loop. It’s pretty cool that this place is sandwiched in-​between Lone Tree Golf Course, Antioch Community Park and Black Diamond Mines Regional Park.
We were here for a hike and picnic. We took the West Shore trail, to the Ridge Trail and veered off up onto the Lake View trail. It’s a pretty good elevation gain, which lends to an awesome view at the top. There really isn’t any place to stop or hang out on the trail. It’s just dirt paths and viewpoints. We were going to stop and eat at the horseman’s camp but it wasn’t anything more than a table, outhouse & hitching post in a parking lot. So, we opted to venture out onto the little island on the reservoir. There are plenty of picnic tables. There’s one area packed with them and it says you can reserve the spot for a party. We chose a private little table at the end of the island. Unfortunately, it happened to be the one table with a trash can next to it and a couple of minutes into our meal, we realized we were sharing our picnic with a team of ants. So, learn from us and scout out the tables away from the trash cans.
The swim lagoon looks really nice and I can imagine families have a great time here in the heat of summer.

Looking for a place to cool off? Go check this place out! Summer in the east bay can get hot. I don’t know how to swim by my girlfriend at the time tried to show me last time I went here and I had a fun time!
Admission is $ 5 per adult but I am not sure how much it is for kids. Sand is available for kids to play in and Plenty of life guards available. It can get busy, so I’m sure it’s a hit or miss depending on which weekend you go. You can BBQ outside this place. You recieve a band which you have in and out privelages.
Bring the family, cook come carne asada or a BBQ. If you’re Mexican (like myself) you know you’ll be taking the whole family! hehe. I am pretty sure any summer holiday (labor day or memorial day) it can get packed!
I’ll be coming here sometime in the future. Perhaps another swimming lesson or just to get a sun tan! bring the whole family! literally and «just keep swimming, just keep swimming, just keep swimming…»
