Blackstone Bay Beach sits at the edge of Whittier, a former military outpost wedged between snowcapped peaks and the gunmetal waters of Prince William Sound. The shoreline is coarse gray gravel polished smooth by tides, scattered with blue mussel shells and kelp ribbons that arrive with each surge. Behind you, the town's singular high-rise—a relic Cold War barracks—looms against vertical rock faces; ahead, the bay opens toward hanging glaciers that glow pale turquoise even under overcast skies.
“This is the only beach in Alaska accessible by car through a single-lane tunnel shared with trains.”

Seabirds wheel overhead—kittiwakes, murres, the occasional marbled murrelet—while bald eagles perch in hemlock snags along the waterline. The beach curves gently, offering sightlines toward Blackstone Glacier in the distance, a river of ice that occasionally thunders as house-sized chunks break free and crash into the sound. The water temperature hovers in the mid-forties year-round, discouraging swimming but perfect for seals, sea otters, and the humpback whales that surface between May and September.
Come prepared for weather that shifts without warning: fog banks roll in dense and damp, rain sweeps horizontally off the sound, and sudden breaks reveal the Chugach Mountains in sharp relief. The beach itself requires no permit, no reservation, just the willingness to embrace Alaska's moody coastal beauty in a place where the mountains don't gently slope to the sea—they plunge.
