Decatur Shores Airport (DTR)

Decatur Shores Airport (WN07) serves Decatur Island in Washington State's scenic San Juan Islands archipelago, positioned 8 miles northeast of Anacortes at 38 feet elevation in the pristine Puget Sound waters. Operating as a private-use facility since January 1972 in San Juan County, the airport features a single runway with operational procedures requiring landings to the north and takeoffs to the south, accommodating general aviation traffic serving this exclusive island community and recreational destination. The facility provides basic infrastructure for private aircraft operations accessing Decatur Island's secluded residential properties, recreational activities, and natural attractions within the renowned San Juan Islands region. Located among a network of island airports including nearby Blakely Island Airport (9 km), Lopez Island Airport (9 km), and Friday Harbor operations, Decatur Shores serves as part of the essential aviation infrastructure connecting these remote island communities where ferry service alternatives may be limited or inconvenient. Operational considerations include coordination with Seattle ARTCC, navigation using Seattle sectional charts, and awareness of the surrounding Puget Sound seaplane operations including nearby Fishermans Bay/Lopez Seaplane Base and Friday Harbor Seaplane Base. The airport supports private aviation access to one of the Pacific Northwest's most desirable island destinations, enabling convenient transportation for residents, visitors, and recreational pilots exploring the natural beauty, marine activities, and peaceful island lifestyle characteristic of the San Juan Islands archipelago.
