We usually do our own excursions independently from our ship's. However, we are thinking about a couple of tours offered by our ship in Martinique.
First, what is the "bat cave"? (I've noticed it is not mentioned in a guidebook on the Caribbean that I have.) A snorkeling tour offers a photo stop here, then it's on to some other location to snorkel. How is the snorkeling in Martinique in general?
Another tour offers some sightseeing by bus and one of the stops is the volcano museum at Mt. Pele. The trip back to the port is described as a scenic ride by a twin engine powered boat. It's always nice to see an island from the sea - at least for me. I wonder if the bus ride is a good one or one of those that can put you to sleep?
By the way, our ship is only there from noon til 7 p.m. and we must board by 6:00.
