We decided to stay here one more day so we can take a ferry from Campobello to Dear Island so we can see the Largest Whirlpool, it is located between Eastport, Maine,  USA and Dear Island, New Brunswick, Canada.  

The ferry.

 

The Whirlpool is best seen 2-3 hours before high tide, however, we were told that it can be seen 'mid-tide'....so we were there about 2hrs after high-tide and there wasn't much of a 'show' by the "old sow".  But here's info:

 

Apparently, at her peak, there can actually be a meter or more 'drop in the center of the whirlpool!  We did see a picture in a museum in Eatport, ME....and it was a dramatic "hole" into the ocean.
