About 14 miles past the Hwy 89/89A fork, Hwy 89A crosses the Navajo Bridge over the Colorado River at Marble Canyon. Actually, there are two bridges: one built in 1995 and a historical one from 1929. Walking across the latter, you'll enjoy fabulous views down Marble Canyon to the northeast lip of the Grand Canyon. The Navajo Bridge Interpretive Center on the west bank has info about the bridges, as well as the area's natural wonders. Keep an eye out for California condors!
Just past the bridge, a stunning 6-mile drive leads to the fly-fishing mecca of Lees Ferry. Sitting on a sweeping bend of the Colorado River, it's in the far southwestern corner of Glen Canyon National Recreation Area and a premier put-in spot for Grand Canyon rafters. Fishing here requires an Arizona fishing license, available at local fly shops and outfitters such as Marble Canyon Lodge.
