Upper Horsetail Falls, also known as Ponytail Falls, can be seen by a short but steep hike from Horsetail Falls. The Horsetail Falls Trail #438 takes you behind the upper fall and through a basalt hafl-tunnel before leading to Oneonta Trail #424. Be aware there are steep cliffs in places, so use caution.
The parking area provides accessible parking spots, however visitors will need to cross the Historic Columbia River Highway to access the viewing area and picnic tables.
