Great Lake, in Tasmania's Central Highlands, has several boat ramps managed by Hydro Tasmania, serving one of the state's most popular angling destinations.

Named ramps include Swan Bay, Cramps Bay, Tods Corner, Brandum Bay, and Boundary Bay on the western shore, with Boundary Bay capable of launching at lower water levels than the others.

Swan Bay Boat Ramp, located off Highland Lakes Road, is a dual-lane concrete ramp with a central pontoon. It is owned by Hydro Tasmania and exposed to north-westerly and north-easterly weather; a white navigation light is positioned on the shore nearby.

Car parking and toilets are available in the area. Water levels in Great Lake can fluctuate significantly, and ramp accessibility changes accordingly.

Boaters are advised to check current conditions before launching, as some ramps may be closed or offer marginal conditions during periods of low water.
