South Harbor
South Harbor sits right on the Petersburg waterfront in Southeast Alaska, giving you easy access to the Wrangell Narrows and the surrounding island-studded Inside Passage. It's a full-service marina with fresh water at the slips and can accommodate vessels up to 60 ft LOA. Petersburg itself is a tight-knit Norwegian-heritage fishing town, worth exploring for its seafood, local character, and proximity to LeConte Glacier — the southernmost tidewater glacier in North America. Call ahead to check slip availability, especially if you're rolling through during peak season.
