The main road circles the entire island along the coast, and the center of the island is dominated by Mount Epomeo.

The most populated area is the northern coastline, where Casamicciola, Ischia Porto, and Forio are located. This is the most developed side of the island, where the southern coastline is wilder. The north of the island is also where most of the ports are located.

Most of the inhabited parts of the island are rather flat, except for Mount Epomeo, and there are long stretches of sandy beach along the coastline.
