Birch Bay Waterslides

Birch Bay Waterslides is a small, family friendly waterpark in Washington State that's been serving the local community for nearly 40 years. It's a unique attraction in Birch Bay with next closest waterslides more than 100 miles away.

The park offers a total of 8 large waterslides, including classic body slides, a six-story tall speed slide, enclosed tube slide, and two open tube slides.

Thrill-seekers will want to try Hydrocliff, a high-speed, nearly straight down bodyslide that descends 60-feet. The park's most popular ride is the River Ride where you and your friend friend ride down a flume on a single or double tube.

For youngsters, Birch Bay's shallow kiddie pool with beach style zero entry has three gentle slides just for kids. There is also a giant hot tub for soaking.
