Seward, Donaldson, Emmons Trail is a 15 mile moderately trafficked loop trail located near Tupper Lake, NY that features a river and is rated as difficult. The trail is primarily used for hiking and is accessible year-round.
This is a very difficult and long loops that will take you over 3 more peaks for the ADK 46'er's. Pending on the time of year, this trail can be very muddy. To complete this loop, start off my heading down the trail until you reach a sign that says Calkins Creek Lean-tos. It says 4.9 miles but you'll turn off before that. When you come to a cairn in the middle of the trail, with an upside down bucket, go to the left. You'll follow the trail for maybe 15 minutes and cross the brook. Depending on the water level, might depend on how easy or hard it is to cross. After you cross the brook, the trail is pretty easy to follow, however there is a lot of muddy parts and blown down trees. Continue all the way to the ridge near the Donaldson summit. There is a cairn which marks the ridge. If you turn to the left it'll take you towards Seward. I suggest going to the right, climbing a rock face and maybe 10 minutes past that is the Donaldson Summit. There is a rock with an odd shape crack on it, that is the summit rock. Another 45-60 minutes and you'll reach Emmons. Its a little steep, but take your and time and you'll be fine. Back track to the cairn and continue down the hill towards Seward. There are some steep scrambles so extra care is required. It should only take about 45-60 more minutes to the summit. Then if you keep following the path you start the "expressway" down. Be very very carefully heading down. Its very steep and wet. It'll take about 1-2 hours to reach the main trail which is marked with a cairn and its near a bridge. Turn left and follow for about 4 miles. You'll pass one set of lean-tos (Blue Berry) and just keep following till you reach the parking area.
This is a very hard climb. 15 miles 10 hours. It is very muddy and parts of it have a lot of blown down tress. It is umarked however the path is defined enough. You shouldn't have an issue following up. Use Calkins Brook to head to the ridge/summit. Take your time, some parts are steep and wet and some muddy parts are very deep. There is a cairn that marks the ridge. Go to the right to knock out Donaldson and Emmons, back track and continue towards Seward. Be careful. The rocks are slippery and steep. The expressway on the other side heading down is even harder but faster. Once you hit the main trail, another 4 ish miles and your home. Good luck.
