Park Overview

Turn Island Marine State Park sits approximately 900 feet off the east coast of San Juan Island in the San Juan Channel, creating an intimate island camping experience within the larger San Juan Islands ecosystem. As part of the San Juan Islands National Wildlife Refuge, the island maintains strict wildlife protection standards while offering primitive camping opportunities on a small butte above the shoreline. The U.S. Fish and Wildlife Service owns the land while Washington State Parks manages the campsites and visitor facilities.

The island’s unique positioning provides paddlers with scenic water routes and serves as a strategic base for exploring the broader San Juan Islands region. Visitors can paddle to nearby Friday Harbor for supplies and dining, or use the island as a launching point for multi-day island-hopping adventures through this protected marine environment.

Facilities & Amenities

Turn Island Marine State Park provides essential but minimal facilities designed to support primitive camping while protecting the sensitive wildlife environment. Restrooms are available for campers and day users. Unsheltered picnic tables serve day-use visitors on a first-come, first-served basis. Two mooring buoys accommodate visiting boats, with phone registration available at the buoys.

The main access point is the cove on the northwest harbor, while the western cove should be avoided due to an extending reef from the small adjacent island. No potable water is available on the island, requiring visitors to bring all drinking water. No garbage services operate on the island, making Leave No Trace principles essential for all visitors.

Camping & Accommodations

Turn Island Marine State Park offers 12 primitive campsites available on a first-come, first-served basis. Campsites are positioned on a small butte above the beach, providing elevated views while maintaining easy beach access. No reservations are accepted, and sites fill quickly during peak season due to the island’s popularity among kayakers and boaters.

All camping is primitive with no hookups, electricity, or running water. Campers must be completely self-sufficient and pack out all waste and garbage.

Planning Your Visit

Access to Turn Island Marine State Park requires boat transportation, with kayaking being the most popular method. Visitors can launch from Jackson Beach on San Juan Island or from Anacortes, though paddlers should be aware of tides and currents, particularly around the aptly named Danger Rocks between Turn Island and Jackson Beach. Turn Point County Park provides another nearby launch option.

Due to wildlife protection requirements, fires and dogs are prohibited on the island at all times. The island operates under Leave No Trace principles with no garbage collection, requiring visitors to pack out everything they bring. Winter camping is available, though seasonal considerations for water conditions and weather become more critical during off-season visits.

What to Bring & Know

  • All drinking water needed for your entire stay, as no potable water is available
  • Complete camping and cooking gear suitable for primitive conditions without fire access
  • All food and supplies, as no services exist on the island
  • Garbage bags to pack out all waste following Leave No Trace principles
  • Weather-appropriate gear for changing marine conditions and potential wind exposure

Final Word

Turn Island Marine State Park delivers an authentic San Juan Islands wilderness experience where kayakers can camp steps from pristine pebble beaches while respecting the delicate balance of this protected wildlife refuge.

Gear Up for Washington Weather

Washington trails are wet more often than not, and the right gear makes the difference between a great day out and a miserable one. We recommend KEEN Targhee IV Waterproof Hiking Boots for solid traction on muddy and rocky terrain, a North Face Alta Vista Rain Jacket because you will need it even on days that start sunny, and the REI Co-op Flash 22 Pack to carry your layers, water, and snacks. All three are available in men's and women's versions. (affiliate links)
