Montague Island: Alaska’s Largest Chugach Island Wilderness

Why Montague Island Stands Out

Montague Island is the largest of the Chugach Islands, stretching roughly 50 miles along the outer edge of Prince William Sound. Its rugged coastline mixes sheltered bays with exposed Pacific beaches, while interior forests of Sitka spruce and alder give way to alpine meadows. The absence of roads or permanent settlements keeps the island wild, making it a prime destination for travelers seeking genuine Alaskan remoteness rather than developed attractions.

Getting There

Access begins from the mainland communities of Seward, Whittier, or Cordova. Most visitors charter a boat or take a floatplane across the sound; the crossing from Seward typically takes three to four hours by vessel, depending on weather and route. Once on the island, movement is by foot, kayak, or skiff. No public ferry service exists, so independent travelers must arrange round-trip transport in advance and plan for weather delays.

Best Time to Visit

June through early September offers the most reliable weather windows, with long daylight hours and calmer seas. Peak summer also coincides with salmon runs that draw harbor seals, sea otters, and occasional brown bears to the shoreline. Shoulder months of May and September can be pleasant but bring higher chances of rain and stronger winds. Winter travel is possible only for experienced expeditions equipped for extreme conditions.

What to See and Do

Kayakers favor the protected waters of Montague Strait and Zaikof Bay for day trips or multi-day paddles. Beaches along the southern shore frequently host resting sea lions and otters. Inland, unmarked trails lead to small lakes and ridgelines with views across the Gulf of Alaska. Anglers cast for halibut and rockfish from shore or small boats. Birders watch for puffins, murres, and bald eagles nesting on cliffs. Overnight camping is permitted on most public land; choose established sites above the tide line to minimize impact.

Wildlife Viewing Guidelines

• Observe marine mammals from at least 100 yards; never approach hauled-out seals or sea lions.
• Carry bear spray and practice proper food storage when camping inland.
• Stay on durable surfaces to protect fragile tundra and beach vegetation.

Nearby Destinations

From Montague, boaters can continue to Hinchinbrook Island or the smaller islands of the Chugach group for additional paddling routes. Prince William Sound’s tidewater glaciers lie roughly 30 miles northwest, reachable in a long day by fast boat. Many charters combine Montague with stops at the abandoned settlements of Port Chalmers or the historic lighthouse on the island’s eastern tip.
