Unalaska Island | Unalaska Lake kitesurf and wingfoil spot
United States · Alaska
Overview
Unalaska Lake is a freshwater lake on Unalaska Island in the Aleutian Islands. This spot offers a freshwater alternative to the extreme ocean spots of Dutch Harbor and Unalaska Bay. The lake is surrounded by tundra hills and provides calmer water than the ocean, although winds remain powerful. Williwaws (katabatic winds) from Makushin Volcano can hit the lake with violence. This is probably one of the most remote freshwater kitesurfing spots in the world. Short season from June to August.

On the water
VERY COLD water (4-12°C/39-54°F in summer) — dry suit MANDATORY. Fresh water, colder than the ocean. The bottom is a mix of sand, mud, and rocks. The lake provides flatter water than the ocean, with moderate chop in strong winds. No tides or marine currents, but winds can create significant waves on the lake. The lake is modestly sized — limited sailing area.
Hazards
Williwaws (katabatic winds) — violent, sudden gusts descending from mountains. Very cold water — rapid hypothermia without dry suit. EXTREME remoteness — no rescue services nearby, nearest hospital is in Anchorage (1,300 km/800 miles). Extreme weather conditions even in summer. Frequent fog. Limited sailing area. Tundra and rugged terrain around the lake. Wildlife: Aleutian foxes, eagles. Never sail alone.
