The National Tourism Office (tel. 28310/29-148) is on Venizelou, the main avenue that runs along the town beach. In high season, it's open Monday through Friday from 8am to 2:30pm; off-season, its hours are unpredictable. But there are numerous private travel agencies that can arrange trips to anywhere on the island. Try Ellotia Tours at 155 Arkadhiou (www.rethymnoatcrete.com).
