Hiked Isolation with Al via the Rocky Branch trail, just an out and back. This trail is always wet but it was even more water than I've ever seen, most of the hike was in a stream on Rocky Branch and the Isolation trail. 14 miles with 3500 ft of ascent....shouldn't be that hard but I felt it. Gorgeous warm weather and breezy at the summit. Terrific views of Mt Washington and the S Presidentials. Only one more visit to this one and I'll be done! I like this hike in winter best...
