We had a fantastic boat tour along the Amalfi coast from Positano to Amalfi and back. We enjoyed the tour on the boat deck. We made a 1-hour stop in Amalfi and visited the cathedral there. Afterwards, we went to a restaurant right on the coast for lunch (Ippocampo, be sure to try the Furore Bianco). Then back to Positano, where we snorkeled in the sea for another 1/2 hour from the boat. A great day. Small note for others: If you come to Positano from Sorrento by boat, please note that the 9:30 am ferry is practically never on time and you arrive in Positano with about a 30-minute delay.
