About Cavern Falls
Cavern Falls is a tucked-away cascade set within San Juan County’s Cypress Island Marine Biological Preserve, a designated MPA. The falls drop into a small pool framed by lush, forested slopes, creating a peaceful spot to rest and listen to running water. This site is on land owned by DESG and managed under the preserve by OTHS, so visitors should be mindful of local protections and leave-no-trace practices while enjoying the scenery. The approach feels intimate rather than grand — a short, wooded walk that rewards hikers with a quiet swimming-sized pool and the gentle roar of the falls. Because the waterfall sits inside a marine preserve, the setting often feels removed from crowded recreation areas, making it a lovely choice for an easy nature outing or a short photo stop on a longer day of exploring the San Juan County islands.
Trail Description
The access route to Cavern Falls is a 2.5-mile out-and-back trail with roughly 300 feet of elevation gain and is generally rated moderate. The path is described as well-marked, weaving through dense forest with a mix of flat sections and gentle inclines; expect some muddy or slippery spots after rain. Official USFS-specific trail surface, grade, and class data are not provided for this route, so hikers should plan for natural tread and typical backcountry footing rather than a hardened or graded trail.
