Grotta di fornillo

Grotta di Fornillo is a sea cave near Positano you can reach by boat for just 5 euro — one of the more affordable natural attractions along this stretch of the Amalfi Coast. The visit is short, around 20 minutes, so it's a quick and memorable detour rather than a half-day commitment. The rugged, cave-carved coastline gives it a raw, untouched feel that contrasts nicely with the polished towns nearby.
