Best time to visit Squak Mountain State Park

Late spring through early fall, roughly May to October, offers the driest trails and the most reliable weather for hiking and trail riding at Squak Mountain. Summer brings long daylight hours and cool forest shade under the canopy, while September and early October add fall color with fewer crowds. Winter access remains open but expect muddy trails, downed limbs after windstorms, and occasional snow at the higher elevations. Shoulder seasons are ideal for RV travelers who want quieter trailheads and easier parking.

Things to do at Squak Mountain State Park

  • Central Peak Trail Moderate

    The Central Peak Trail is the classic summit route to the forested high point of Squak Mountain at about 2,000 feet elevation. The out-and-back climb passes through mature second-growth forest with the ruins of the old Bullitt Fireplace near the top. Views are limited by tree cover, but the workout and quiet forest make it popular with locals.

  • Bullitt Fireplace Trail Moderate

    This historic spur leads to a stone fireplace and chimney that remain from the former Bullitt family cabin on the mountain. The site makes a scenic turnaround point on a loop hike and offers a glimpse of the area's conservation history. Expect a steady forest climb on well-signed trail.

  • West Access Trail Moderate

    The West Access Trail begins near the May Valley trailhead and climbs steadily through dense conifer forest toward the interior trail network. It is popular with trail runners and hikers looking for a shorter forest workout. The lower section is generally well graded.

  • East Ridge and Phil's Creek Loop Moderate

    This loop combines the East Ridge, Phil's Trail, and connector routes for a varied forest hike on the quieter side of the mountain. Hikers pass small streams, ferns, and big-leaf maple stands. Distance can be tailored from about 4 to 7 miles depending on choices.

  • Mountain Biking on Shared-Use Trails Moderate

    Squak Mountain has a network of shared-use trails open to mountain bikers on designated routes. Riders should check posted signage since some trails are hiker or equestrian only. Expect rooty, often damp single-track typical of the Issaquah Alps.

  • Horseback Riding Moderate

    Equestrian use is permitted on many Squak Mountain trails, with access from designated trailheads that can accommodate horse trailers. Riders enjoy shaded forest routes connecting with nearby Cougar Mountain and Tiger Mountain networks. Check current trail status before trailering in.

  • Wildlife and Nature Viewing Easy

    The park is a quiet spot for birdwatching and wildlife viewing in lowland Pacific Northwest forest. Visitors may see pileated woodpeckers, black-tailed deer, and a variety of songbirds. Streams and wetlands support amphibians and native plant communities.

How to get to Squak Mountain State Park

Squak Mountain State Park sits just south of Issaquah, about 20 miles east of downtown Seattle via Interstate 90, roughly a 25 to 35 minute drive without traffic. From Tacoma the drive is about 45 miles and around an hour via I-405, and from Bellevue it is about 15 miles. RV drivers should note that main trailhead access is via narrow residential and rural roads such as Mountainside Drive and May Valley Road, which have tight turns, steep grades, and limited turnaround space, so large motorhomes and long trailers should scout parking before committing. The nearest major airport for fly-and-rent trips is Seattle-Tacoma International Airport (SEA), about 25 miles west.
