Roche Harbor is located in
San Juan County, on the north end of
San Juan Island.
Roche Harbor was the site of the largest lime works west of the Mississippi in the late 1800s, and required 4000 acres of forest just to keep the kilns running. Roche Harbor sprang up as a company town. Today, many historic buildings have been turned into hotels, shops, and guest accommodations, and the remains of several kilns are visible.
