The park contains the site of the Bullitt Fireplace, a remnant of a vacation home built in 1952 by the Bullitt family, who later donated the land to the state.
The name Squak is derived from the Lushootseed word 'sq'wulqs,' referring to the mountain's shape.
The park area was heavily logged in the late 19th and early 20th centuries, meaning most of the current forest is second-growth.
It is home to diverse bird species including the pileated woodpecker and varied thrush.
The mountain is composed largely of Eocene-age volcanic rock and sedimentary deposits.
Squak Mountain State Park Natural Area spans 1,545 acres in the Issaquah Alps, offering over 13 miles of hiking trails through second-growth coniferous forests. The terrain features significant elevation changes, reaching the summit of Squak Mountain at 2,024 feet. The park serves as a critical wildlife corridor connecting the Cougar and Tiger Mountain massifs. Visitors encounter diverse ecosystems ranging from lush, fern-covered ravines to open forest canopy. Historical remnants of early 20th-century coal mining operations and homesteading sites are scattered throughout the trail network. The park is managed as a natural area, prioritizing habitat preservation over developed recreational amenities. Trails vary from easy valley-floor walks to steep, strenuous climbs leading to vantage points overlooking the May Valley. It remains a popular destination for trail runners and hikers seeking a quieter alternative to the busier nearby mountains.
