RivaRiva (Aghia Irini) is not the only port of Thirassia but it's the one from where starts the only road climbing to Manolas, the village on the cliff. (Unfortunately, we don't have photos of the place.)
SUGGESTIONS USEFUL LINKS
Thirassia is mainly served by small boats from Thira (which dock at Ormos Korfou, at the foot of the cliff), but some ferries stop at Riva, in the north of the island.
