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.

Have pictures from way back when? We would love to see! Send them to us at mustangwaterpark805@gmail.com.

  • 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.

    -Nick S.

  • 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.
