San Juan Island National Historical Park

San Juan Island National Historical Park comprises two separate areas with coastal prairies, woodlands, and marine shorelines. The park spreads across the island and offers different landscapes to explore.

The park preserves American and British military camps established during an 1859 territorial conflict. This dispute played a key role in settling the border between the two nations.

The Coast Salish people shaped this island for thousands of years through their hunting and gathering traditions. Archaeological findings show how deeply connected they were to the land and sea.

Both areas—American Camp and English Camp—are free to visit and each has an information center. The visitor centers provide guidance and background information on what you will see.

Park rangers at English Camp raise and lower the British flag daily in a flag ceremony. This routine is unusual—very few places see US officials handle foreign flags each day.
