A Daycation at Don Castro Swimming Lagoon in Hayward

If a family vacation to Maui is not in the cards this summer, you should check out the swimming lagoon at Don Castro Regional Recreation Area in Hayward. The clear blue water, sandy toddler-friendly beach and shallows, and affordable price all make for the perfect East Bay daycation with your family. I recently took my four kids, ages 3-9, and we all lived our best summer lives at this Hayward gem.

Opening for Summer 2024 weekends and Holidays May 25 – September 15; Monday – Friday: June 10 – August 16.

Don Castro Swimming Lagoon for Families

The chlorinated and filtered water at Don Castro swimming lagoon is lovely, inviting, and clear blue. The roped-off shallow area is ideal for young children to wade, play, and feel comfortable. My younger children loved the shallows and played happily for hours. My older children also enjoyed the shallows, splashing around and playing endlessly all day long. Just remember to reapply sunscreen!

If your kid is an adept swimmer they can take a swim test and then gain access to the deeper section. Or, they can borrow a life jacket for free from the parks department and enter the deep area with an adult. While we were there, most everyone stuck to the shallow area because the water is warmer there.

The Bottom Line on Don Castro Swimming Lagoon

We had a wonderful day relaxing and playing at Don Castro. It was a bit foggy and overcast at first, but like most summer days in the Bay Area, it burned off and was a lovely day by late morning. Weekdays are far less busy, so if you can swing it, try to come mid-week. Otherwise, show up early on a weekend to make sure you get in (they do have capacity limits), or show up later in the afternoon once the early crowds leave. Overall, Don Castro is clean, close, and cheap; the perfect family summer daycation.

    1. Yes, the lagoon is separate from the lake. You’ll drive through gate and follow the road and signs to the swimming area.

  1. You’ll want to call (510) 544-3073 to ask about reserving a spot for a birthday party (they may say it’s first come first served depending on the day/size of your party). There are many tables within the swim area to set up a party.

    Hope that helps!
