The Bering Sea stretches off Alaska’s western coast, linking the Arctic Ocean to the Pacific. It’s one of the world’s largest inland seas, covering about 2.0 million square kilometers (770,000 square miles). This sea sits between Russia’s Kamchatka Peninsula and Alaska’s Seward Peninsula, forming a key ecological and geopolitical corridor in the far north.
Where Is the Bering Sea and Why Does It Matter?
It spans roughly 1,600 kilometers (1,000 miles) from north to south. The sea links to the Arctic Ocean through the narrow Bering Strait—just 85 kilometers (53 miles) wide at its narrowest—and opens into the northern Pacific via the Aleutian Islands. This body of water plays a huge role in global ocean currents, marine biodiversity, and Arctic climate systems. (Honestly, this is one of the most important seas on the planet.) It’s also been a historical migratory route for humans and wildlife, including bowhead whales and Pacific salmon.

The Bering Sea Through Time: History, Science, and Survival
For millennia, Indigenous peoples like the Yup’ik, Inupiat, and Siberian Yupik relied on its icy waters for food and trade. In the 18th century, Russian explorers including Vitus Bering mapped the region, which eventually gave the sea its name. Now, scientists track its rapidly changing ecosystem due to warming temperatures and melting sea ice. These changes threaten traditional ways of life and marine species like ice-dependent seals and cod.
Visiting the Bering Sea: What to Know in 2026
Access is tricky thanks to the remote location and harsh climate. Cruise expeditions—like those from Alaska Cruise Lines—often include stops in Nome, Diomede Islands, and St. Lawrence Island. Travelers can observe walrus colonies and migratory birds there. Just prepare for cold weather, limited services, and strict wildlife viewing rules. Always check National Park Service advisories before heading out.
