Mustang Waterpark is located in the Lopez Lake Recreation Area ~ 10 miles east of the Village of Arroyo Grande & just a few short miles from Pismo Beach or San Luis Obispo. We have two 600-foot curving waterslides joined by the 38-foot half-pipe Stampede for thrill-seekers. For younger children, the Kiddie Pools offer three mini-slides & two waterfall mushrooms, along with sun decks & luxury cabanas.

We are nestled on oak studded hills, overlooking beautiful Lopez Lake, far from traffic & stress. We offer affordable family fun for all ages. Make Mustang Waterpark part of your best family vacation ever.

  • WATERSLIDES

    Two giant 600-foot curving waterslides that take you for an exciting ride from a hilltop overlooking Lopez Lake to splashdown in our catch pools at the bottom. Our park has certified lifeguards at all times to ensure your family’s complete safety.

  • STAMPEDE

    Ride the awesome Stampede!!! Plummet 38 feet down one side of the giant half-pipe in an inner tube, speed 38 feet up the other side, then repeat this wild ride backwards! You can take this amazing ride solo, or go in a double tube with a buddy!

  • KIDDIE POOL

    Your little ones can safely slide and splash in our two inviting wading pools for kids under 48″ in height, three mini-slides and two waterfall mushrooms. Parents can splash with their youngsters or relax in the sun on the deck while the kids have fun in the water and are safely entertained for hours.

WAY BACK WHEN

WAY BACK WHEN

When the waterpark originally opened its doors in the year 1978, it consisted of just two simple waterslides along the slope of the hill that overlooks Mustang Campground. This humble beginning marked the start of a place where families & friends could gather for fun & relaxation for years to come.

  • Great little park, loved the slides & went on them with my kids all day! I really enjoyed all the safety with the huge presence of lifeguards.

  • The perfect water park to take your family to big enough to keep the family entertained all day & small enough to not have to worry about where your children are if you are sitting at your lounge chair.
