I’m not going to sugar coat it: The Blue Grotto is tourist-y AF. During the day, there are dozens of boats stacked with hundreds of people who are all trying to catch a glimpse of the famous cave. My advice? Wait until the end of the day (after 6pm) to take your tour. The water isn’t as blue once the sun has started to move, but the area is way less crowded. This was our last stop on our Positano/Nerano boat tour, and we had the chance to jump out and actually swim in the grotto, which isn’t usually an option when there are zillions of people and boats around. It was still absolutely incredible — I don’t actually know how it could possibly be any bluer than what we saw — and we practically had the place to ourselves.
