Korovin Island: Remote Wilderness in Alaska’s Shumagin Group

Why Visit Korovin Island

Korovin Island sits in the Shumagin Islands of the Aleutian chain, a volcanic landscape shaped by subduction-zone geology. Its steep slopes, sea cliffs, and sheltered bays create habitat for seabirds, sea otters, and occasional brown bears that swim between islands. The island remains roadless and uninhabited, preserving a sense of true wilderness rare even in Alaska.

How to Reach Korovin Island

Access begins in Sand Point on Popof Island, the nearest community with scheduled air service from Anchorage. From Sand Point, travelers arrange boat charters across the 20-mile strait; weather windows are essential because sudden Aleutian gales can close the passage for days. Floatplane landings are possible in calm bays but require prior coordination with local pilots familiar with the island’s limited anchorages.

Best Time to Visit

Late May through early September offers the longest daylight and mildest temperatures, coinciding with peak seabird nesting and salmon runs. June and July bring the densest concentrations of tufted puffins and kittiwakes along the cliffs. September can deliver clear weather but shorter days and the first autumn storms.

Activities on the Island

Day visitors typically land at a gravel beach on the southern shore and hike inland along game trails that climb toward the central volcanic ridge. Binoculars are essential for spotting Steller sea lions hauled out on offshore rocks and for scanning the skies for bald eagles and peregrine falcons. Kayakers can circumnavigate the island in a full day when seas are calm, exploring sea caves and tide pools rich in starfish and anemones. Fishing from the boat for halibut and rockfish is permitted in surrounding state waters.

Wildlife and Safety Considerations

Bears frequent the island’s salmon streams; travelers must carry bear spray and practice strict food-storage discipline. No facilities exist, so all supplies, including water, must be carried in and out. Tides rise and fall dramatically, so boats must be secured well above the high-tide line.

Nearby Destinations

Popof Island’s Sand Point offers basic lodging and a small museum on Aleut history. Nagai Island to the southwest provides additional hiking and another large seabird colony. The larger community of King Cove, 60 miles northeast, supplies medical services and additional charter options.
