The Guemes Mountain & Valley Conservation Area was protected through an unprecedented partnership between Skagit Land Trust,  the San Juan Preservation Trust, and the residents of Guemes Island.  Hundreds of donors contributed to protecting this jewel of the islands. Read all about the Campaign to Save Guemes Mountain and the 2015 Guemes Forever Campaign to expand the conservation area.

“Guemes Island has a long history of visionary landowners undertaking voluntary land conservation. These protected lands add so much value to the island’s heritage. No matter the changes to Guemes Island over the decades, this area will remain rural and natural, and serve as a sanctuary for people and wildlife.” - Carolyn Gastellum, Guemes Island Land Steward 2017.

A generous donation of 127 acres in 2017 expanded the size of the Guemes Mountain & Valley Conservation Area to a total of 206 acres. The Guemes Mountain & Valley Conservation area connects to over 500 acres of public and private land designated for conservation on Guemes Island.

The Guemes Mountain & Valley Conservation Area plays an important role as a buffer to adjacent protected properties along the coastline, including a parcel acquired by the Washington Department of Fish and Wildlife to protect perigrine falcon and bald eagle nesting habitat, as well as habitat for other seabirds that nest along the rocky ledges on the coast. The mountaine prairie, woodland and wetland habitat of the Guemes Mountain & Valley Conservation Area property complements the shoreline feeder bluff of the Kelly's Point property, also managed by Skagit Land Trust on Guemes Island.

History and Ecology

At 688 feet, Guemes Mountain is the highest point on Guemes Island and features stunning views of the San Juan Islands, Mount Baker, the North Cascades mountains, and the Skagit delta.  The mountain features five acres of a unique prairie habitat with a wide variety of wildflowers, including Camus lily, Fawn lily and Chocolate lily. This mountaintop prairie may also serve as important nesting habitat for ground birds. 

The bald top of Guemes Mountain is believed to have been treeless for many years, possibly through a combination of fire (either natural or human-led) and most recently due to logging. Consultation is needed with local Coast Salish tribes for information about the pre-colonial Indigenous use and history of the site.  It is believed that the grassland area was once larger and maintained by pre-colonial Indigenous peoples of the Coast Salish tribes.

The forest lands of Guemes Mountain were logged most recently in the 1990s. Western red alder, willow and other early successional species have begun to revegetate the slopes of Guemes Mountain. Hikers today can find a mix of hardwood, softwood and shrub species including madrone, grand fir, western hemlock, bitter cherry, pacific yew, red flowering current and native rose. The section of trail that transitions from second growth softwoods (douglas-fir and western hemlock) to hardwood species is an excellent place for viewing woodpeckers. 

The lowland portion of the Guemes Mountain & Valley Conservation Area provides habitat for a number of species including  bald eagles, turkey vultures, swallows, warblers, finches, deer, beaver and amphibians. The Guemes Valley portion of the Guemes Mountain & Valley Conservation area protects 30 acres of working farmland and over 40 acres of critical wetland habitat that flow into the island's only aquifer via Cayou Creek.  The Guemes Valley property preserves one of the last remaining active agricultural areas of significance on the island, an expansive area of wetlands, and extensive second growth forest that is well on its way to becoming an older forest ecosystem.

Stewardship

Restoration work on Guemes Mountain & Valley includes removing invasive plant species including: Canada thistle, bull thistle, foxglove, reed canargy grass, St. Johns wort, scotch broom and Herb Robert. Thanks to the hard work of volunteers, the Skagit Land Trust is actively managing invasive plant species on the property.

Guemes Mountain & Valley Conservation Area is part of broader effort of land conservation on Guemes Island and contributes to establishing a wildlife corridor with adjacent properties managed by the San Juan Island Preservation Trust and other land conservation agencies.

Engaging Youth in Conservation

Guemes Mountain & Valley is a popular site for our Engaging Youth in Conservation program. Many groups have visited this site to participate in restoration work and to enjoy the natural beauty. 

The Skagit Land Trust Engaging Youth in Conservation Program provides hands-on learning experiences in nature and connects the subjects they are studying in the classroom to the real world. The program also instills stewardship ethics and shows students the difference they can make in their community. Photograph credit: Skagit Land Trust staff.

The protection of Guemes Mountain & Valley Conservation Area ensures that this scenic location is maintained in a natural state for the public to enjoy. Skagit Land Trust collaborated with Washington Trails Association to build a 1.2 mile long trail up the mountain in 2010-2011.  The trail starts on a trail easement, winding through forest on a neighboring property.  It then emerges onto SLT property, ending at a beautiful mountaintop with views of the surrounding San Juan islands. The trail has an elevation gain of 550 feet. Low impact day hiking is allowed, with dogs on leash and waste carried out. We do not allow biking, horseback riding, motorized vehicles, fires or overnight camping. The habitat at the top of the mountain is unusual and fragile. Please walk on the paths instead of through delicate vegetation.

Parking is available for four cars and a bike rack is at the trailhead. If you bike, bring your own lock. Do not park on the side of the road because parked cars will block the ability of Guemes fire trucks to pass. Since parking is limited we suggest leaving extra cars at the Guemes Ferry free parking lot or in Anacortes.

The Guemes Island General Store has a courtesy bike program, where hikers can ride the ferry and borrow one or two bikes to get to the trailhead. Contact Guemes Island General Store at (360-293-4548) to reserve the bikes. Bathrooms are available where designated above on the map, at the Schoolhouse Park, the ferry terminal, and, for customers, inside of the Guemes Island general store.
