Prince William Sound is a massive, glacier-carved fjord system in Southcentral Alaska. It sits just a short drive from Anchorage. Accessible primarily by boat, float plane, or the Anton Anderson Memorial Tunnel (to Whittier), it offers world-class glacier viewing, sea kayaking, fishing, and wildlife watching.
To explore the Sound, you will launch from one of two main coastal hubs:
Prince William Sound boasts more than 150 glaciers and abundant marine life.
The primary visitor season runs from late May to early September. Summer brings the warmest weather, the longest daylight hours, and the peak of the salmon runs. If you want to see spawning salmon and bears feasting on them, the best time to visit is mid-July to August.
