The Larc Tour is the best way to discover the Town of 1770 coastline. While "pristine" is an over and often mis-used adjective, it's pretty tempting to stick it into a description of the  coastline of Eurimbula National Park.  The Larc is a clunky amphibious vessel that seats 32. It came into service with the Australian Army in 1964 for military and flood-relief operations. It's both an obvious, yet slightly bizzare, means of transgressing the waterways and sandbars around the National Park. Kids love it as much as the adults.  The journey is informative, beautiful and a hoot!
