Hello. We would like to take a full day boat tour around Capri (including Blue Grotto) and time to spend on the island. We'd like to catch the boat in Positano where we are staying. Does anyone have a recommendation on who we can travel with for this tour. Thanks in advance for help. Jamie
Have you checked the local TI? That generally is a good starting point.
Just FYI, Jamie: you will have to pay an extra fee and transfer from your tour boat to one of the rowboats operating at the Grotto. You might want to browse reviews on TA from people who found that process very time-consuming and not worth the few minutes inside the thing? The many reports of badgering by the boatmen for tips is troubling as well.
Depending on tides and wind, access isn't a guarantee either. We skipped it entirely during our stay on the island.
