The Lowe River through Keystone Canyon gives rafters a brief, yet very enjoyable introduction to whitewater less than 20 miles (32 km) northeast of Valdez. While the rafting trip takes only an hour, the canyon doesn't lack either spectacular scenery or exciting whitewater. Its nonintimidating Class II-III rapids can be enjoyed by anyone above the age of five.
      The raft trip, which starts approximately 1 mile (1.6 km) above Keystone Canyon, includes a midtrip stop at Bridal Veil Falls, where waters cascade 900 feet down rock walls to the river bank.
      Keystone's outfitter provides rainsuits, life jackets and rubber boots.
