About Hidden Falls

Hidden Falls is a secluded cascade tucked into the forested slopes of Cypress Island Marine Biological Preserve in San Juan County, Washington. Nestled within this marine-protected area (MPA), the falls sit on land managed by OTHS and owned by DESG, offering a peaceful retreat framed by dense evergreens, moss-draped rocks, and a small pool at the base. The setting feels intimate and quiet — a lovely spot for photographers and hikers looking to escape busier Puget Sound destinations. The route to the falls rewards a modest effort with tranquil, verdant scenery rather than dramatic elevation. Because the site lies inside a designated preserve, expect an experience that emphasizes natural character and low-impact visitation; visitors often describe the atmosphere as restorative and shaded, with the steady hiss of falling water underscoring the forest sounds.

Trail Description

The trail to Hidden Falls is an out-and-back route of about 2.5 miles total with roughly 300 feet of elevation gain, rated moderate in difficulty. The path is generally well-maintained but can become uneven or muddy after rain, and hikers will pass through dense vegetation and moss-covered rock areas as they approach the cascade. No USFS trail name or number is listed for this route, and specific USFS surface, grade, or class data are not available for this trail; expect natural tread typical of preserve trails rather than paved or heavily engineered surfaces.

What to Expect

Visitors can expect a peaceful hike through a forested area leading to a beautiful waterfall. The sound of cascading water and the natural surroundings make it a great spot for relaxation and photography.
