Northwest of Seattle on Whidbey Island, the 645 acre Fort Ebey State Park makes a great base for exploring the 28 mile Kettles Trail Network. The mountain bike trail network runs along a series of kettles covered with plush flora. The trails roll through the hills about the Strait of Juan de Fuca and are on well-packed dirt/sand.
To reach the mountain biking trailhead from Seattle, take exit #189 off of I-5, just south of Everett. Follow signs for the Mukilteo/ Clinton ferry. Take the ferry to Clinton on Whidbey Island. Follow Hwy. 525 north, which becomes Hwy. 20. Two miles north of Coupeville, turn left on Libbey Rd. and follow it 1.5 miles to Hill Valley Dr. Turn left and enter park.
Overall, Kettles Trail Network is the 22nd most popular mountain bike trail of all 59 mountain biking rides in Washington.
