The towns are unspoiled by tourism. Most development is in Patitiri and Alonnisos. Remarkably, every house has a cesspit, so no sewage enters the sea. This regard for ecology has resulted in many benefits for Alonnisos.
Post earthquake housing
projects of the government resulted in the new construction
of Patitiri, the island's bustling main port and only major town. 
Although of new construction, the town is fairly pleasant and islanders
have
further beautified it with many plants and bouganvillea vines. There are very nice craft stores, for those inclined towards shopping.
Patitiri Town is the site of the Society for the Study and Protection of the Monk Seal where you can see some videos and learn more about these endangered animals.
A small beach is in Patitiri and a nicer one lies at Votsi a bit to the north. Just to the south is Marpouta with the sunken remains of the Temple of Asklepios the Healer, and the even nicer beaches of Megalos Mouritas and Vithisma.
Old Alonissos or Hora (Chora), 5 km west of Patriti still retains period architectural remnants of pre-quake days. The ruins of its Venetian castle are still visible. The towns walls were originally built by the Byzantines and subsequently restored by the Venetians.
Hora is reachable by paved road or on foot by donkey path which passes through nut orchards. You're rewarded for the steep climb by scenic views far above the sea. Sunsets are often particularly lovely.
Heading back down from Hora, a 20 minute walk will bring you to sandy Vrisitsa beach. An hour's hike from Hora is the wonderful Bay of Ormos Gialai.
