Get to know the largest fish in the world: the gentle hiu paus, or whale shark. Members of this endangered species migrate near Gorontalo every year, hanging around between June and September. You can hire a boat and a bucket of prawns (125,000Rp, one hour) to float the 20m or so offshore and chum for new friends. The government regulates activity to protect the sharks, limiting how many boats or swimmers can be out at once. Report harassment.
