Photo Caption: Cruising through the Lemaire Channel, Antarctica What Not to Miss: Highlights include passing through the towering blue icebergs of the Lemaire Channel and seeing icebergs with their steep sides and flat tops at the entrance to the Weddell Sea. Kayaking and "beach" landings are a must. Best Time to Go: November through February; the window is short because the rest of the year is too cold (try 50 degrees below zero!) and too dark.
