The Hackberry and Horseshoe Trail Head is about five miles north of the Park Headquarters at Hovenweep along paved Road 10, then down a primitive dirt road. The turn off is marked with a small bird symbol rather than a sign.
The Holly Ruins Group is another 0.8 mile down the same dirt road. The first view of the standing structures of the Hackberry Group is from a short spur trail that views across the canyon. There are rubble remains on both sides of the canyon.
From this angle, the Hackberry trees growing in the relatively moist canyon bottom can be viewed. The rim environment is Pinon Pine and Utah Juniper with patches of Sage Brush, Mormon Tea and Prickly Pear Cactus.
