While you don’t need to be super fit, you will gain the most enjoyment from the expedition if you can walk a few hundred metres without difficulty and unassisted. Most hikes ashore are leisurely strolls along beaches, however, there are some more strenuous walks on offer, where there may be uneven terrain and loose stones. An alternative excursion will always be offered in place of higher impact walks. During the cruise, there may be a couple of swimming opportunities in freshwater pools.
