Ziplines have become very popular in Southcentral and Southeast Alaska, with zip cables, suspension bridges and rappel stations anchored in towering spruce, hemlock and birch trees. Every Alaska zipline adventure offers unreal, thrilling views guaranteed to keep you on the edge of your harness: craggy, snow-capped mountains, dense forests in layered shades of green and rivers and lakes turned a rich turquoise by water from melting glaciers. You'll have a chance to practice with the equipment and review safety procedures before taking your first steps into the trees, where the guides will also teach you fascinating information about Alaska's uniquely untouched ecosystems.
