Hearst Lodge is located on Big Salmon River, off of the Fundy Trail Parkway near St. Martin's New Brunswick. There is a trail along the river, and a roadway to get there. You cannot drive there.
We walked in the roadway, and came back by the trail. I would much advise this route. Either route involves hiking up a long steep hill on the roadway. It's much nicer to do this uphill hike at the beginning in my opinion. Besides, the hill at the park end seems much easier to climb than the one at the lodge end.
The hiking trail is labelled 'challenging', and I would agree with that, though none of us (3 youngish seniors) had any problems negotiating the roots, rocks, washouts and steep spots.
It took us a little over an hour to hike in by the road, and 2 hours to hike out by trail, which included a few stops to admire the scenery and have a snack.
