Bruny Island is made up of two parts, North Bruny Island and South Bruny Island. The two parts are connected by an isthmus and although both offer fantastic landscape, the south island has more to offer the visitor. The main town on the island is Adventure Bay, where you can buy supplies and also stay. You can also find out about the history of the island at the Bligh Museum of Pacific Exploration. Although the other settlements do each have a small shop and possibly a couple of places to stay, it is best to take your own supplies with you and book accommodation beforehand.
Around the island there is plenty of wildlife to see and things to do, as well as good swimming and surfing beaches. To the south of South Bruny Island is the South Bruny National Park, which offers spectacular scenery and some great walking tracks. West of this is the South Bruny Lighthouse which is the second oldest in the whole of Australia, built in 1836.
There are plenty of cottages and guesthouses around the island where you can stay, although you should book your accommodation at the Bruny D'Entrecasteaux Visitors Centre in Kettering. You should also ask here about the mail bus, which can take you around the island on its mail run. Other than this there is no public transport on the island and so you should either take your own or hire bikes, which is a very pleasant way of seeing the island. The ferries leave several times daily from Kettering.
