The 'problem' with walking on the carriage roads is that the bridges are sometimes difficult to view. (This website has more photos of some of the bridges.) It was easy walking along the carriage roads, even the uphill grades weren't too bad, and it was a pleasant way to spend the afternoon.
This bridge was at the southern end of Jordan Pond.
Another view of the same bridge in the previous photo.
This little bridge was near the Bubble Pond.
