PELNI

Pelni's offices are on the port, but to leave Sulawesi, you'll have to go to Palu: the boats passing through Poso are local coasters. If you take them, you can circumnavigate the entire peninsula in two weeks, via Togian to Luwuk. It's not an expensive cruise: these boats sail at night and dock in ports during the day.

From Poso to Togian Islands: Mondays and Wednesdays at 10 pm.

To Wakai (with a stop at Ampana) Monday's boat sails to Gorontalo, arriving on Wednesday at 10am.
