That is a little early for foliage. Mid-late Oct. southern NE, Late Sept-Early Oct Northern NE. We are still wearing summer clothes w/ occasional sweater at night the first week of Sept.
If your want to see soem Lighthouses the one that you pass for sure is on Hangmans Beach as you come into the Port Of Halifax. It will be on your right/starboard side as you enter Port.
Interesting story about the Beach is this is where they use to hang any Mutineers/Criminals back in the 17/1800's. It was for all the Sailors to see and not get any ideas.
