Alderbrook Park

Alderbrook Park is a 63-acre private park in Brush Prairie, Washington, nestled in the forest with nature trails, a creek, and its own three-and-a-half-acre Mirror Lake. The grounds serve as an outdoor destination for corporate picnics, private celebrations, and community events, with four covered pavilions plus an overlook deck and lookout tower hosting groups from 25 to 750 guests. A day at the park comes with plenty to keep guests busy: a heated swimming pool with wading area and sundeck, pedal boats on Mirror Lake, an 18-hole mini golf course, disc golf, beach volleyball courts, softball and kickball fields, horseshoes, train rides on the Alderbrook Express, a pirate ship play structure, and hiking trails. A main stage facing the Alderbrook field sets up for movies, concerts, festivals, and team-building events. All food and drink is handled on site — the park's catering team serves private events, and the Snack Shack/Alderbrook Cafe covers concessions. Parking accommodates more than 1,000 cars.
