Yes, visiting both Positano and Amalfi in a single day is entirely possible and a very common itinerary for travelers based in Sorrento or Salerno in 2026. To make the most of the experience, it is highly recommended to start your day early (around 8:00 AM) and utilize the ferry system rather than the SITA buses. Ferries offer a much more scenic perspective of the vertical coastline and avoid the heavy traffic of the narrow "Amalfi Drive" road. A typical route involves taking a 30-minute ferry from Salerno or a 50-minute boat from Sorrento to Amalfi in the morning to explore the historic Duomo and the Paper Museum. After lunch, you can take another 20-minute ferry to Positano to wander through its boutique-lined alleys and relax at the beach. While you won't have time for a long hike like the Path of the Gods, you can comfortably see the highlights of both "pearls" before returning to your home base by late evening.
