The park offers a wide variety of activities, including swimming, boating, fishing, horseback riding, and hiking.

Fifteen miles of hiking trails lead through an ancient forest with centuries-old trees and ridges and ravines carved by volcanic and glacial flows.

Metro, the park's managing body, leads ancient forest walks, animal tracking workshops, and wildflower and mushroom identification classes.

The area’s natural habitat makes an ideal home for wildlife such as mink, beaver, raccoon, fox, deer, osprey, elk, black bear, and cougar.

The two-day event draws up to 10,000 visitors who can see spawning salmon; enjoy music, food, art, storytelling, and a fish maze; and encounter a variety of traditional activities and cultural exhibits at Wy-Kan-Ush-Pum village hosted by the fishing tribes of the Columbia Basin, including the Nez Perce, Umatilla, Yakama, and Warm Springs tribes.
