That depends entirely on your travel style and goals, but for most visitors, a full day is ideal and recommended.
Here’s a breakdown to help you decide:
Positano is about soaking in the atmosphere, not just ticking off sights. A full day allows you to: Explore without rush: Wander the steep, picturesque pathways (like the Via dei Mulini), browse the boutique shops for linen and ceramics, and get lost in the charm. Enjoy the beach properly: Secure a spot at Spiaggia Grande (rent a sun lounger or just lay a towel), swim in the Tyrrhenian Sea, and enjoy the iconic view of the town from the water. Have a leisurely lunch: Dine at a cliffside restaurant with a view. This is a highlight of the Positano experience. Visit Fornillo Beach: Take the scenic path to the slightly quieter Fornillo Beach for a different perspective. See a landmark: Visit the beautiful Church of Santa Maria Assunta with its iconic majolica-tiled dome. Stay for the magic hour and dinner: The town transforms at sunset. Having dinner as the lights twinkle on the cliffside is unforgettable. Take a short boat trip: Use your time to take a quick ferry to nearby Amalfi or a boat tour to see the coast from the water.
A full day lets you experience the “dolce far niente” (the sweetness of doing nothing) that the Amalfi Coast is famous for.
