The
main island has two roads, one from the port of Patitiri to the Old
Town and the other from Patitiri to the northern tip of the island,
with a side road branching off to
Steni Vala and Aghios Dimitrios.
There are taxis and bus service between Patitiri and the Old Town from June to September, ranging from four buses daily to nine or twelve in the high season. Cars and motorcycles can be rented, but most transportaion is by boat. Water taxis serve the main beaches, with larger boats sailing around Alonissos and further north to the deserted islands of the Marine Park. Hikers will enjoy following the old mule track down to the port.
The islands best beaches are reachable by small boat or caique and most of them have snack bars or tavernas in the summer.
Ancient Allonissos town (5th C BC) is at Kokkino Kastro (Red Castle) and has a nice shingle beach just 25 minutes by caique. North of Patitri the first really nice beach is Chrysi Milia (Golden Apple) in a small cove surrounded by pines and three tavernas. The best fishing and water sports are to be found further north at Kalamakia and Steni Vala. Kalamakia and Steni Vala have small pensions where rooms may be let. The next beach north, Aghios Dimitrios boasts ruins of a Byzantine fountain and an ancient settlement by the shore. Prehistoric animal fossils have been discovered at nearby Megliamos beach which is lovely and usually deserted. The best diving is to be found at Gerakas, an old sheperds village, and Hodros Kavos where divers can enjoy unusual fish and underwater caves.
