Our family has an absolute blast at Splash Down Cove every summer! It’s never too crowded, which means more time to enjoy the water without long waits. The water slide is a favorite—we always race to see who can get the fastest time! Clean, fun, and perfect for all ages. Can’t wait to come back again next season!

Came with my kiddos since we were passing through. When we first got here staff at the desk was super great and seemed happy to help. Once we got to the outdoor splash cove things felt a little different. Lots of life guards out keeping an eye on things which as parents we were excited to see. Well , my son who is a very tall 5 year old (already over 4ft tall) and a great swimmer was told he couldn’t swim in the 3 1/2ft area or do the lazy river without an adult. At first I thought he miss heard them so my husband check with one of them. Sure enough….them were the rules. For the price and restrictions put on kids on what they can and cannot do it just seemed odd and not worth it for us. It also felt like we were being stared at while sitting and watching the kids in the kiddy pool area. I had a life guard tell me that outdoor food wasn’t allowed in the area we were in. I asked what food she was referring to. She then pointed to the capri suns and liquid death we bought at their food stand… she then went, “oh you did…I didn’t know we sold those here…. I don’t know just some weird incidences combined that made it not so enjoyable. I understand safety is big in this type of environment but I think the next time we are thinking of an out of town swim trip we will stick to Moses lake or lake chelan.

Awesome place. The staff is very friendly and helpful. Totally worth the money. Very relaxing great atmosphere and the slides and lazy river are very fun. Also there is a basketball hoop in the pool.

Hands down the best water park between Walla Walla and Pendleton Oregon. There's only a little bit of a spending your side but it is totally worth it. Definitely a place to take your kids and chill while having fun in the sun.
