Basin Trail is a 8.2 mile out and back trail located near Intervale, NH. The trail is primarily used for hiking.
I only did the first part of the trail - Wild River Campsite to the Overlook just past the Rim Trail Junction. It was a beautiful hike. One of the best I have done yet in the Whites. Not difficult at all and quite a view at the top for your effort. There is no rock scrambling required and only a few steps greater then 12". The trail seemed well used and we met quite a few people. But bring your map! There are so many junctions it is easy to get turned around, we had to show two groups our map.
The trail starts with a simple walk through the woods with some big bridges. Then it follows a creek up, there is one crossing, which could be a challenge if the water was high. Following the creek is steady up and beautiful! Once you leave the creek you have about a half mile to the overlook, and that is most of the elevation.
The AMC map says this segment is only 2.3 miles, but the sign at the top (and my GPS) both said it was 3, with a couple side trips (including to scope out a nearby tent site) it made a nice 8 mile round trip.
We have hiked the Basin Trail from Basin Pond Campground to the Basin Rim junction several times. The hike starts off fairly flat then ascends steadily to the base of a large cliff. After skirting around the cliff, the last 100' is a steep scramble.
The view out over Basin Pond is well worth the effort.
The trail does continue over the ridge and on, but we usually return the way we came.
