Time Out says
Setting off from Cres town, Cres Sail offers three types of sailing tours: daytime, sunset and at night. From the gentle hour of 9am, the relaxed one of 6pm or, for braver souls, 10pm, Marko and his crew take you out for a full exploration of the waters off Cres island. The all-day option is a full 12 hours, the all-night one, until 8am. Those with less time and a smaller budget can go for the four-hour sunset chill trip, and still have plenty left in the tank by the time they dock at 10pm.
