The Island of Lipari is ideal for trekking. There are many routes on the island from easy to hard level. The level of difficulty depends on the season. Some tracks are very hard or almost impossible to follow during summer because of the heat. There are maps to be bought on Lipari but one has to ask local people to find some of the tracks.
A short walk downhill can be done on the road from Quattropani to Acquacalda on the north side of Lipari. This can be done even during summer and takes about 45 minutes. You enjoy the view of Salina and the northern Aeolian islands during this walk.
From the Old Kaolin Mine between Pianoconte and Quattropani it is possible to walk to the thermal bath of San Calogero or to the village of Quattropani. Downhill near the sea there is the ruin of a Saracen tower and fifthy meters away it is possible to walk down on the black clifs for a bath.
Do these to walks during springtime. From Marina Corta there is a track up to Monte Gallina and Monte della Guardia. You reach the west side of the island and will enjoy the two Faraglioni from upside. You are able to reach the street that takes you from the vulcanologic observatory in front of Vulcano, back to Lipari town. You should do this hike late afternoon during summer. During afternoon in summer you can also make a walk from the church of Santa Lucia in Lipari to Valle Muria, the beach on the west side of Lipari.
Lipari is the best-equipped base for island-hopping, with plenty of places to stay, eat and drink.
