The well-signed trail system consists mostly of abandoned roads that are narrowing to single-track trails, more so each year. One such road-trail leads to a foundation and fireplace that is the remnant of the Bullitt's summer home. Distant views are infrequent because of the forest; the attraction of Squak Mountain is the urban wilderness.
Residential development in Issaquah extends to the park boundary at about 1,100 feet in elevation. The park is accessed from a trailhead (elevation 740 feet) at the hairpin turn of Mountainside Drive in the north, and the signed state park entrance on May Valley Road in the south (elevation 350 feet). A lesser trailhead is found on the Renton-Issaquah Road on the west (elevation 400 feet). Other trailheads may be reached via Sycamore Drive SE and Sunrise Place SE.
