The Gulf of Alaska is a vast, open coastal sea area forming the primary marine boundary for much of southern Alaska. Paddling here is an expedition-level undertaking characterized by exposure to significant ocean swell, powerful tidal currents, and rapidly changing weather. The coastline is rugged and remote, with access points typically being small coastal towns or specific locations within national parks. Launch and take-out areas include the town of Yakutat, the Visitor Center in Glacier Bay National Park, and the Seward Small Boat Harbor for trips into adjacent Resurrection Bay and Kenai Fjords National Park. The tidal range in Southeast Alaska can be substantial, reported as 12 to 18 feet, making careful timing essential for beach landings and navigating steep boat ramps at low tide. Currents are a critical factor, especially in narrow passages and inlets connecting to the Gulf, such as Sitakaday Narrows, Inian Passage, and North Passage, where currents can exceed 3 knots and must be timed for safe passage at or near slack water. The open coast has extensive fetch, leading to significant wind-driven swell; paddlers often hug the mainland inside rock lines for protection when possible. Major hazards include the potential for strong winds, large ocean swell that can induce seasickness, and the presence of coastal grizzly bears on beaches. The water is frigid year-round. The overall experience is one of profound wilderness, with sights including tidewater glaciers, icebergs, towering mountain ranges like the Fairweather Range, and abundant wildlife such as whales, seals, sea otters, and puffins. Multi-day expeditions along routes like the Inside Passage, which uses barrier islands to buffer the Gulf's swell, are common, with trips lasting 30 to 40 days. Travel occurs within protected areas like Glacier Bay and Kenai Fjords National Parks, which have their own regulations. Guided day trips and shorter excursions are available from operators in Seward and other towns, focusing on more protected fjords and bays adjacent to the Gulf.
