By transfer
There are two transfer companies on Kangaroo Island, they can arrange for you to be transferred to anywhere on the island
Getting around can be difficult if you don't bring or hire a car. However, there are plenty of one to three day tours to jump on, which can be booked in Adelaide and on the island, and there are some scheduled coaches between the towns, and transfer services to the airport and wharf. The island has 1600km of roads, both sealed and unsealed, and is 155km long.
There are no taxi services on the island.
All towns are small and can be explored on foot.
By Tour
Most tours run between 1 and 3 days and operate from Adelaide. If you make your own way to the island you can normally join a tour group at a reduced cost.
There are the "adventure" tour style, and the more traditional style tours stopping at the produce providers and major island sites on a fairly fixed itinerary. It is even possible to do a day tour from Adelaide very tiring and you don't get to see the nocturnal animals.
Extended backpacker style tours of 2 and 3 days combine camping, budget accommodation, adventure and wildlife viewing, some even offer surfing.
By bus
There is a shuttle service operated twice daily by Sealink between Kingscote, American River and Penneshaw. Booking is necessary.
An Airport shuttle operated by KI Transfers meets all daily flights from Kingscote Airport and can arrange transfers to anywhere on the Island. For details visit (http://www.kitransfers.com.au)
By car
Make sure you have plenty of fuel before you start your trip. Petrol stations are generally only in the main settlements and frequently close before 6PM. In the south and west, petrol is only available at Vivonne Bay and Wilderness Retreat near Flinders Chase. Most roads are good, there is little need for a 4WD. Petrol is more expensive than on the mainland.
By bike
Both Bicycle Rental and Bicycle Tours are available on Kangaroo Island. Bike rental is available when you get there.
