Spin your way through the miles of single-track carved throughout the greenery within Japanese Gulch in Mukilteo [1]. This forested slice of private land rests on a ravine and is accessible from Mukilteo Boulevard. Park in the lot at Centennial Park (1126 5th St.) and cross the street to ride. The park offers a nice square of grass to sit on during a leisurely post-ride picnic.
