Loch Vaa is a 39-acre (16 ha) spring-fed freshwater loch which is said to have "gin clear" waters. The loch is owned by a local estate but leased to a number of businesses for fishing, swimming and boating activities. The fishery is managed and the lake is stocked with brown and rainbow trout; it is also frequented by wild grebe. The loch's wooden boathouse, which is used for fishing, is surrounded by water and is a popular destination for tourists and photographers. 
The loch contains the remains of a crannog, a historic fortified structure constructed on an artificial island. Birch timber recovered from the Loch Vaa crannog dates it to the 13th century, though the structure may be even older - dating back to the time of the Picts or earlier Iron Age peoples.
