About

Water-park destination featuring a variety of rides, a lazy river, and a restaurant.

Specific pool temperatures for Castaway Island are not publicly advertised. As an outdoor water park attraction, the water temperature is generally ambient and dependent on the prevailing weather conditions, rather than being actively heated to a specific degree.

What are people saying (AI review summary)? The water park is generally well-regarded, especially for families with children, offering engaging activities like the lazy river, lagoon (with a note to watch small kids in one backwash area), and excellent tube slides. Guests commend the well-maintained facilities, friendly staff, and secure environment. However, the park often experiences significant crowds, particularly on weekends, in fine weather, and in areas like Castaway Island. Recurring concerns include limited shade and very expensive food, with visitors often recommending bringing their own. There's also a suggestion for adding more thrill rides, such as a water coaster, and some feel other parks offer more.

Spectacular place for kids, lots of fun and engaging activities for water play. It can get very busy during weekends and in fine weather. Keep in mind that there is limited shade and really really really expensive food options here. Highly recommended to binge food and shade if weather permits.place is locked down with only one entrance and exit so kids are sede.

Great time! The lazy river was my family's favorite! Not too crowded for a Saturday.

I think Water Country offers more but my daughter and I enjoyed our time. The lagoon was the best part. Just floating along with the waves was fun. Only issue with the lagoon was a section at the end of the entrance where the water backwashes into a culvert under a statue. People did get stuck for a moment, so, if you have small kids, you may want to watch them. Nice locker rooms.
