The best person to ask about when to travel to each cruise destination is, quite simply, the skipper. Because these cruises are all about what you are going to see when you wake up in the morning, as opposed to what the breakfast buffet is going to be like. Therefore, the dates of travel are usually linked to wildlife sightings or the best sailing weather. In Antarctica, Nov-Mar is not only the best to go, it is the only time. For Arctic small cruises, it’s the summer. If you want to see porpoises, basking sharks and whales in Scotland, the summer months are also best. The Galapagos have animal magic going throughout the year.
