      Grand Ridge is both an oldie and a new trail: while new residential development wiped out some of the trails we rode in the past, a new trail system has been under development by King County Parks and the WTA. (Check out wta.org for work parties.) You access it the same way as ever: by climbing up from I-90. The trail can also be accessed from the top of the Issaquah Highlands development.

      The main trail winds north across Grand Ridge towards Duthie Hill Park.

      This is a great XC work out, with great climbing practice. Plus, it can be linked with trails on the south side of I-90 to create longer loops. This trail connects with Duthie Hill Bike Park and 1 short mile of road riding to continue up to Soaring Eagle for a suburban epic.

      The climb from I-90 up to the plateau is a grunt, but not too long. When coming from Duthie Hill, the long climb up to Grand Ridge Drive is even more of a grunt, and is pretty darn hard to clean on a single speed. With gears, it's still a fairly physical ride.
