While we were in Vermont, we visited an old railroad that had been turned into a path for bikers and walkers.
It extends about three miles out into Lake Champlain towards the Islands, and sometimes there is a bike ferry at the end so bikers can go over to the islands and continue on their journey. My husband walked out to the end and went fishing and I walked out for a short bit with him. The scenery is beautiful but you must walk to one side to keep out of the way of the hoards of bikes that travel down the path. Here are a few of the pictures I took on the causeway.
