Check out the helpful website operated by Symi's delightful and informative independent monthly, The Symi Visitor (tel. 22460/71-785; www.symivisitor.com). Through the site's e-mail option, you can request information on accommodations, buses, weather, and more. Don't ask them to recommend one hotel over another; explain exactly what you're looking for and they'll provide suggestions. Once you're on Symi, you'll find free copies of the latest Symi Visitor at tourist spots.
The long-established Kalodoukas Holidays (tel. 22410/71-077; www.kalodoukas.gr) can help with everything from booking accommodations (often at reduced rates) to chartering a boat. Once you've arrived on Symi, drop by the office at the base of the stairway to Horio (where there is another office; Mon–Sat 9am–1pm and 5–9pm). In summer, this agency plans a special outing for every day of the week, from cruises to explorations of the island. Most involve a swim and a healthy meal.
A tourist information kiosk on the harbor keeps hours that remain a mystery. Information and a free pamphlet may also be obtained at the town hall, located on the town square behind the bridge.
