Insider Tips
Prince William Sound solitude: Granite Bay offers protected anchorage in Esther Passage — sheltered from the open Sound. Pro tip: The granite walls of the bay create excellent acoustics — listen for the breathing of humpback whales echoing off the rock. Intertidal: Giant sunflower sea stars (up to 3 feet across) inhabit the low tide zone.
Best Time to Visit

Frequently Asked Questions
Is Prince William Sound affected by the Exxon Valdez spill?
The 1989 Exxon Valdez oil spill devastated Prince William Sound. Over 30 years later, most species have recovered, though some — like Barrow’s goldeneye and pigeon guillemot populations — remain below pre-spill numbers. The Sound is once again a vibrant marine ecosystem.
