Quick Overview

Petersburg has several RV dump stations in the area, with some offering free access to travelers in the fishing town of Little Norway on Mitkof Island in Southeast Alaska's Inside Passage. This community of about 3,200 sits along the Wrangell Narrows, a winding 22-mile channel that larger cruise ships cannot navigate, keeping Petersburg refreshingly free of the mass tourism that dominates other Southeast Alaska ports. RV dump station and sani-dump access in Petersburg serves the travelers who arrive via the Alaska Marine Highway ferry system and explore a genuine working fishing town where Norwegian heritage, commercial fishing, and Southeast Alaska's temperate rainforest create a distinctive community character. The sanitary dump station facilities provide tank maintenance at a port where the shrimp and halibut fleet ties up along the harbor and the pace of life follows the rhythm of the tides and fishing seasons rather than cruise ship schedules. Petersburg's Norwegian heritage dates to the town's founding by Peter Buschmann in 1897, and the community maintains Scandinavian traditions including the Little Norway Festival each May. The LeConte Glacier south of town is the southernmost tidewater glacier in North America, accessible by boat tour from the Petersburg harbor. The Tongass National Forest surrounding the community provides hiking, fishing, and wildlife viewing in one of the world's largest temperate rainforest ecosystems, where bald eagles, bears, whales, and salmon are regularly visible during the summer and fall months. The Stikine River delta to the south is one of the largest river deltas on the Pacific coast and provides outstanding bird watching during spring migration when millions of shorebirds stage on the tidal flats before heading north to their Arctic breeding grounds.

Traveling to Petersburg by RV

Petersburg is accessible only by air or the Alaska Marine Highway ferry system -- there is no road connection to the mainland. The ferry system serves Petersburg from Juneau, Wrangell, and other Southeast Alaska communities, with vehicle space requiring advance reservation during summer. The local road system on Mitkof Island extends about 35 miles, with the main road running south from town along the island's eastern shore. Roads handle RVs adequately though they narrow in sections. A small grocery store and fuel station serve the community. Cell coverage works in the Petersburg townsite but drops off on the island roads beyond town. The Wrangell Narrows approach by ferry is spectacular, winding through dozens of navigation markers in a passage too tight for large cruise ships.
