Camping opportunities are relatively rare in Europe, but this island in Malta has cheap camping. on the other inhabited islands (Malta and Good), public transit, restrooms, and wifi are plentiful and local food is extremely cheap. You can get local tfira for a couple euros or a passtizzi filled with peas or cheese for even less. With an ultralight pack, all of Gozo is walkable, though the island of Malta is split by a largely impassable highway. I’d recommend the bus for €2.50.
