Trail Run the Grand Ridge Trail

Grand Ridge Park

Easy access to trailhead from multiple parking lots. Quick trip from Seattle. 14 miles of trails within Grand Ridge Park. 1,100-feet of elevation gain, good for all skill levels. Good for hiking, trail running, mountain biking, and equestrian. No pass or permit required.

The trail system in the 1,300 acre Grand Ridge Park can currently can be accessed from two lots: High Point and Central Park, with a new lot at Duthie Hill still under construction.

To get to the High Point lot take exit 20 off of I-90 (coming from Seattle), take a left and pass under the freeway and park in the gravel lot on the left-hand side.

From here the trail starts flat and wide before veering up the hillside and meandering through large cedar trees and ferns. As the elevation levels out, bikers and runners alike will enjoy being able to cruise the gently rolling singletrack. The Grand Ridge trail is an out-and-back and while there are generally maps at the intersections, some are missing so it's wise to carry a map with you.

Overall rating: 

MTB as well!

Did this in combination with Duthie Hill, and it was sweet. Went on a Tuesday which helped, but hardly saw anybody on the trail and it was a well groomed trail. The initial downhill to the boardwalk and then a climb gets a good workout in. Overall pretty fast and flowy, fun trail!

Nice single-track trail tucked away from the city

The first few miles of the Grand Ridge Trail off of Exit 20 are thick with vegetation and sprawling, scenic switchbacks. Make sure you pay attention to each intersection you take - if you hug the trail too far west you'll end up downtown Issaquah like I did, and have to backtrack to regain the trail farther up in the foothills. Like most trail systems in the PNW, this thing turns into a mud bath after heavy rains, so be prepared for some mud trudging.
