An altogether different Antarctica activity is sea kayaking, an ethereal experience that is hard to describe. You can paddle your way through the tranquil waters of Antarctica no matter your level of fitness, always accompanied by experienced guides and a small group of fellow kayakers. One of the most relaxing yet overwhelming excursions on offer, sea kayaking comes with an added level of quietness which, coupled with the gargantuan landscapes, makes for a soul-stirring experience. This is, unsurprisingly, one of the most popular optional activities on Antarctica cruises and most guests book their slot even before boarding their ship. You may want to do the same as this is the one amazing activity you won’t want to miss.
