I guess but man that is not easy, particularly if they weren't seasoned hikers. Just not sure what the hell the group was doing in there to start with. It's 4.5 miles from the GG trailhead to the junction of that trail. Did they go up that way? Descend down it from another route and stop? Puzzled by this one. Looking forward to more details on it.
I love the Wamsutta Trail, especially that section after the steep climb that opens up in scrub and there is a big rock pile that has a slab that makes for a great chair (maybe 4600-ish feet or so) staring right at the Northern Presi's. The approach in along the river in the Great Gulf is awesome as well. Try to get in there at least once every year. Did a phenomenal sunset/moonrise/sunrise hike this Fall going up that trail, cutting across the Alpine Garden in the dark (and some much higher than planned winds), bivied for a bit and watched the moonrise, and doing the sunrise at Lion Head before dropping down into the woods and making the big cruise back to GG trailhead.
