Fort Schwatka

Most of the Aleuation WWII National Historic Area preserves Fort Schwatka on Mt Ballyhoo, the highest coastal battery ever constructed in the USA. Looming nearly 1000ft above the storm-tossed waters of the Bering Sea, the US Army fort encompassed more than 100 concrete observation posts, command stations and other structures built to withstand earthquakes and 100mph winds.

The gun mounts here are still among the best preserved in the country and include tunnels that allowed gunners to cart ammunition from one side of the mountain to the other. The 1634ft mountain is behind the airport and can be climbed to look at military artifacts or enjoy excellent views of Unalaska Island. A dirt road leads to the top and is picked up half a mile north of the ferry terminal along Ballyhoo Rd. It's about an hour's climb to the top.
