The Joggins fossil cliffs are outstanding. Definitely worthy of recognition as a world heritage site. I have visited the site several times over the last 10 years, most recently in November of 2008. My son is doing a project for the National Heritage Fair and has chosen Joggins as his topic.
The staff at the fossil center (despite the center not being open) met with us and spent 2 hours answering my sons questions, taking us down to the cliffs on a very blowy and cold afternoon and generally being exceedingly kind and helpful.
The center is beautiful and the cliffs are highly interesting. I can't wait to visit on a warmer day in 2009.
