Bettles Bay State Marine Park
⚓ A Glacial Fjord Anchorage in Prince William Sound — Where Tidewater Glaciers Meet the Sea — Bettles Bay State Marine Park in Prince William Sound, Alaska, near Whittier, protected boat anchorage in Passage Canal, kayaking, camping, glacier viewing, wildlife (sea otters, harbor seals, bald eagles, humpback whales), Tongass-influenced rainforest, boat or kayak access only — near Whittier, AK
Prince William Sound is 15,000 square miles of glacial fjords, tidewater glaciers, and cold emerald water. Bettles Bay is a protected cove in Passage Canal — the narrow waterway that connects Whittier to the open Sound. You drive through a 2.5-mile tunnel to reach Whittier. Then you put your kayak in the water and paddle into one of the most dramatic marine landscapes on Earth.
No dock. No trail. No ranger station. Just a protected anchorage in a fjord where glaciers calve ice into water so cold it turns your fingers white in minutes. Sea otters float on their backs. Harbor seals watch from the rocks. And the mountains rise 4,000 feet straight from the waterline.
What to Do
| Activity | Details |
|---|---|
| Anchorage | Protected anchorage in the bay — good holding in mud bottom, shelter from Passage Canal winds. Popular overnight stop for vessels transiting to or from western Prince William Sound. The mountains block the worst weather |
| Kayaking | Sea kayaking from Whittier into Passage Canal and the bay. The waters near Whittier are the most accessible kayaking in Prince William Sound — you can paddle from the harbor into glacier country in hours. Water taxi services extend your range |
| Camping | Primitive beach camping above the tide line. No facilities. Bear canisters required. The forest behind the beach is dense Sitka spruce and hemlock — rain and wind are constants |
| Glacier Viewing | Passage Canal provides access to Blackstone Bay and its tidewater glaciers — Blackstone, Beloit, and Northland glaciers. Icebergs float in the channel. The glaciers are retreating but still calving |
| Wildlife | Sea otters (hundreds in Passage Canal), harbor seals on ice floes and rocks, Steller sea lions, humpback whales, orcas, bald eagles, black bears on shore. The Sound is one of Alaska’s richest marine ecosystems |
