With plains full of wildlife to hills of granite, Custer SP is definately worth a visit. Custer is also home to the famous Needles Highway. This winding stretch of two lane passes under canopies of green and then along the rocky cliffs. There are three short tunnels to pass thru, two are just under 9 feet wide with the center “Needles Eye Tunnel” at about 8 feet, too tight for our dually. Along the 18 mile Wildlife Loop we saw buffalo and a small herd of burros. Although the rangers advise not feeding them, these are the most well fed creatures in the park as the tourists bring bags of apples and carrots, among other treats, for them.
