There aren’t a lot of options for getting around Samosir Island. Most people rent a motor cycle for the day or take a tour with one of the many tour operators on the island. The cost for renting a motor bike is around 70,000 rupiah for one day.
The ferry does make a few stops at the different hotels on its way back to Parapat, but around Tuk tuk, it easy to get around on foot.
Some hotels rent out bicycles. There is not a lot of traffic on Samosir Island, but the roads do get hilly in places.
