Beautiful hike on an old railroad alignment. There were a couple of snowmobiles that were very polite when passing.


This was a great, easily accessible showshoeing trail. The drive to St Elmo is beautiful and a the trail was great for taking dogs. The ony major drawback was the abundance of showmobiles roaring by.
