Hope Island Marine State Park stands apart as one of Washington’s most conservation-focused marine destinations, where 176 acres are designated as a Natural Area Preserve to protect rare serpentinite ecosystems. The bedrock forming this unique island consists of serpentinite, a metamorphic rock formed at tectonic plate boundaries from Earth’s mantle material, creating distinctive geological features and specialized plant communities found nowhere else in the region.
The park serves visitors seeking a true wilderness island experience while maintaining strict ecological protections. Unlike typical state parks, recreational activities are confined to designated areas on the north shore, preserving the island’s critical habitats for nesting herons and other sensitive wildlife species.
• Primitive Camping – Six first-come, first-served campsites on north shore bay with basic amenities
• Boating & Moorage – Two mooring buoys available for overnight stays with phone payment system
• Wildlife Observation – Herons nest on southwestern end, eagles and marine life viewing opportunities
• Beach Access – Sandy beaches and rocky shorelines for exploration within designated areas
• Kayaking Access – Popular paddling destination accessible from Cornet Bay and La Conner area
• Photography – Unique serpentinite rock formations and protected ecosystem views
• Sunset/Sunrise Viewing – Boaters frequently anchor offshore for spectacular bay vistas
• Nature Study – Educational opportunities to observe rare geological and biological features
The park maintains minimal facilities to preserve its wilderness character. One vault toilet serves campers and day users, located 100 feet south of the designated camping area. A pay station near the eastern campsite allows visitors to pay camping and moorage fees. The two mooring buoys on the north side accommodate boats, with payment available by calling Washington State Parks. Fires are allowed in designated fire pits and grills, with propane and gas grills permitted.
Hope Island Marine State Park (Skagit County) offers six primitive campsites on the north shore bay, all available on a first-come, first-served basis.

No potable water is available on the island. Check-in time is 2:30 p.m. and check-out is 1 p.m.
Access to Hope Island Marine State Park requires watercraft only, with no ferry service available. Popular launching points include Cornet Bay boat launch in Deception Pass State Park, where overnight vehicle parking fees apply. The park operates year-round with seasonal hour adjustments. Moorage fees are $23 per night for buoys, with additional charges of $1 per vessel foot for dock access.
Dogs are not allowed anywhere on the island due to sensitive wildlife areas and Natural Area Preserve protections. Visitors must pack out all garbage as no waste collection services exist. Most of the island remains off-limits to recreational use to protect the designated preserve areas. Weather conditions in Skagit Bay can change rapidly, so boaters should monitor marine forecasts and tide conditions.

This Hope Island Marine State Park is a 200 acre island in Skagit Bay in Skagit County, near the mouth of the Skagit River. It is one of two Washington state parks named Hope Island, and this one is a Natural Area Preserve reached only by boat or kayak.
There is no bridge or ferry, so access is by private boat, kayak, or paddlecraft only. Visitors can tie up at one of the mooring buoys or the dock, and there is a pay station for moorage fees on arrival.
Yes, in a primitive way. The island has 6 first come first served primitive campsites and a vault toilet, but no developed hookups or running water. Pack in everything you need and pack out all trash, since it is a protected natural area.
Hope Island protects sensitive habitat, including unusual serpentinite bedrock and native plant communities, so it is managed as a Natural Area Preserve. Visitors are asked to stay on established trails and beaches and leave the landscape undisturbed.
The park is open from 6:30 a.m. to dusk in summer and 8 a.m. to dusk in winter. Moorage runs about $23 for a buoy or $1 per vessel foot at the dock, and because access is by water there is no vehicle Discover Pass to buy.
