Getting there:

The Tamar Wetlands is about 10mins out of Launceston CBD on the West Tamar Highway, Riverside. There are plenty of car parking spots just off the highway. The walk starts from the interpretation centre which is staffed by volunteers and heads out to Tamar Island.

Route/Trail notes:

This is an easy access boardwalk which leads you 2km out to Tamar Island for a short loop then returning to the Interpretation Centre. Total of 4km. Plenty of birds (over 50 species) and in the warmer months copperhead snakes enjoy lazing in the sun. 

A self-guided brochure is available from the Interpretation Centre which is quite informative as you complete the walk.

Permits/Costs:

There is no cost to park your vehicle, enter the Interpretation Centre or complete the 4km walk. Donations are accepted as the Centre is staffed by volunteers.
