Camp Sealth is located on nearly 400 acres of forest and wetlands on the southwest shore of Vashon Island, Washington. The property includes over a mile of saltwater beach along Colvos Passage. Our main camp area is right beside the water and features a large play field, dining hall, meeting spaces, and most of the cabins.
Upper camp can be reached by car or on foot and includes two large play fields, the Wrangler Retreat Center, Uncle Wigglebottom’s cabin, campsites, and miles of hiking trails. Most of our property is undeveloped, allowing kids and adults to explore and learn about the natural world.
Our Historical Property
Camp Sealth celebrated 100 years of camping on Vashon Island in 2020. While all of our facilities have changed over the past century, some are older than others. While all are lovingly maintained, our site is one of the oldest in the region and some of our facilities reflect their age. Please note that we are not a hotel or luxury retreat center. We strive to ensure that every guest is comfortable during their stay, but offer a friendly reminder that we are first and foremost a camp.
Our sleeping cabins and our meeting spaces will keep your group cozy while surrounded by the natural beauty of the site. The images below offer an idea of the range of our spaces, and we welcome you to visit our property ahead of your retreat for a tour.
Meeting Spaces
Camp Sealth has meeting spaces throughout the property suitable for groups of different sizes. Our largest meeting space can accommodate up to 400 people and our smallest space fit groups up to 20. Most spaces feature views of the Puget Sound or our surrounding forests.










Sleeping Accommodations
All of our cabins are heated with lights and electrical outlets so are suitable for year-round use. Most cabins have 2 large rooms with 8-10 twin-sized beds with impermeable foam mattresses (most as single beds but some as bunk beds) for students and 1 small room with 2-3 twin-sized beds for chaperones. Please note that Camp Sealth does not provide any bedding for any students or adults, so all guests must bring a sleeping bag, sheets, pillow, and any other bedding items they might want themselves.
Most cabin units have bathroom facilities in a separate nearby building from the sleeping cabins, except for our Wrangler Retreat Center which includes bathrooms within the cabin. All cabin unit bathrooms have separated toilet and shower stalls with a set of communal sinks.
