We are lucky enough to be able to visit Magnetic Island as often as we like so we tend to forget that large parts of it are inaccessible. Nearly everyone lives in the string of bays (Picnic, Nelly, Geoffrey, Arcadia) along the east coast, plus Horseshoe on the north coast. The other half of the north coast can only be reached by boat, and the middle by serious off-track bushwalking. What about the west coast?
We had a car on the island recently (we’re usually bus dependent) and took the opportunity to visit West Point for the first time in more than ten years. There’s a road leading all the way (10 km or so) to a small settlement at West Point but it’s rarely used because most of it is a very pot-holey dirt track. We suspect the residents like it that way: buses don’t go there and hire vehicles aren’t permitted to go there, so most tourists can’t go there.
