Joggins Fossil Cliffs is just a 2.5 hour drive from Halifax, Nova Scotia airport.  The site is in a rural area located right on the Bay of Fundy.  I was fortunate to visit on a beautiful day in May at low tide.  As a result, I was able to walk below the cliffs to see how the extreme tides of the Bay of Fundy is eroding the cliffs and exposing fossils of trees and other plant life.  The various coal seams and ridges of fossil remains along the beach also made the site visually interesting.

You'll need a car to visit this site as it is a couple of hours from - well - anywhere.  Fortunately, the roads are great and there is no traffic.  Once there, definitely make time to visit the Joggins Fossil Center - part museum/gift shop/visitor's center.  Also, the 2 or 4 hour tours offered by the Fossil Center staff are excellent.
