During off peak times the last ferry back from Parapat is 6pm. The cost of the ferry is 7000Rp. Buy your ticket on the boat. At the ferry wharf and on the ferry you will be approached by many of the local young men trying to persuade you to go to the hotel they are affiliated with. These guys are mostly harmless and just trying to make a living guiding tourists. They can be a good resource for information. There is no harm in going and checking their hotel out and if you're not happy with that hotel move on to the ones close by. Tuk-tuk is not that large so the hotels are close. See the list of hotels at the bottom of this page.
