Semiahmoo Marina is the Northwest’s premier resort boating destination. Nestled between the San Juan Islands to the south and the inland waters of British Columbia to the north, boaters will find that Semiahmoo’s breathtaking moorage, surroundings, generous amenities, and slip ownership opportunities provide an unparalleled boating experience.
