Swift River: Bear Notch Road to Kancamagus Highway is a 10.5 mile trail located near Conway, NH. The trail is primarily used for whitewater kayaking.
Was unable to do the whole route since Bear Notch Road had not been open for the season, yet. Still had two - three feet of snow. Went a few miles fishing in waders down Douglas Brook until running into a bear that should have been hibernating. Cutting the trip abruptly. Pretty in the snow, however. Nice hiking.
Water can be extremely cold.
