Twillingate, Newfoundland and Labrador, Canada is know as the iceberg capitol of the world.  Located along famous "iceberg alley", Twillingate is a great place to watch for icebergs in Spring and early Summer as the ancient ice floats down from the arctic.  
The best period to view bergs is between late April and early June as they may sometimes be locked up in sea ice. This video was taken from the Cliffs near the Twillingate lighthouse.
