To access Crystal Cascades a short hike of about 15 minutes is required up Mt. Washington’s Tuckerman Ravine trail. The trail starts at the Appalachian Mountain Club Building in Pinkham Notch,NH. As you walk through the White Mountain National Forest you will cross over the cutler river. The falls is just ahead. Make sure to take a wide angle lens as it will give you the best compositions. The falls is interesting to shot at any time of the year.
