The Lemaire Channel in Antarctica is a strait between the mainland continent and an island. On a calm day you will have calm blue water that reflects the amazing snow capped mountains. The first time we tried to cross the channel it was blocked with a straight line of icebergs due to the winds. When we tried the 2nd time we were able to get through. This is one of the most beautiful landscapes in Antarctica and if you are going to the last continent on your adventures around the world I would highly recommend that you convince the captain of your cruise ship to take you there.
