Lake Usma
A large Kurzeme lake studded with wooded islands, used for sailing, fishing and lakeside camping.
Updated 1 September 2026
Usmas ezers is the fourth largest lake in Latvia, around forty square kilometres of shallow water in the Kurzeme forest with a scatter of wooded islands, of which Moricsala is the largest and is a strict nature reserve, protected since 1912 as one of the oldest in the country and closed to visitors. The lake is used for sailing, windsurfing, kayaking and fishing, with pike, perch, bream and eel, and campsites, guesthouses and boat hire operate around the shore, particularly on the western side. The surrounding country is pine and spruce forest with bog areas. It is a quiet lake compared with those nearer Riga.
