Activities
Features
Turtleback Mountain Preserve is one of the largest (1,718-acre) undeveloped places in the county. Treasured by islanders for its dark, undeveloped ridge line, it is a refuge for wildlife and a haven for those who wander the trails through a mosaic of forests, wetlands and open meadows. Sheltering a variety of special habitats and species, the Preserve is ecologically significant as well as beautiful. Grasslands and Garry oak woodlands cover the mountain’s dry southern slopes while conifer forest blankets the remainder. Pocket wetlands scattered about the property provide crucial habitat for wildlife and moisture-loving plants. Seasonal drainage from the mountain nourishes the fertile wetlands of Crow Valley and the rich marine habitats of West Sound. Towering over Crow Valley and West Sound, Turtleback Mountain is visible from many vantage points throughout the county and is one of the most familiar and beloved landscapes in the San Juan Islands.
A major conservation effort in 2006 with partners and citizens made Turtleback a reality, and more recently, our partnership with San Juan Preservation Trust expanded and connected public access from Turtlehead to Turtleback via what is known to the community as “Turtleneck”. Turtleback Mountain Preserve has been protected through the efforts of the Conservation Land Bank, the San Juan Preservation Trust, the Trust for Public Land, and more than 2,000 private donors.
