The Trevallyn Dam Boat Ramp sits on Lake Trevallyn Road, accessed via Reatta Road in the Trevallyn locality on the outskirts of Launceston, Tasmania.

Owned by the Parks & Wildlife Service, the facility features a single-lane concrete ramp with an adjacent jetty and walkway. Note that lake levels fluctuate, which can affect launch conditions.

The ramp's incline can be challenging for 2WD tow vehicles, though the concrete surface provides reasonable traction. A small car park is located just uphill from the ramp. Toilets are available nearby.

The surrounding Trevallyn Nature Recreation Area protects dry open grassy forests, woodland, and riverside habitats along the South Esk River.

Most of Lake Trevallyn is open to boating and fishing, with the exception of waters near the dam wall and penstock intake.
