Zipline Tour, Koloa
Concierge.com's insider take:
Inspired by the zip lines he saw in the rain forests of Costa Rica, Rick Haviland came home to Hawaii and installed his own zip line in the pastoral Kipu Ranch, enabling guests to harness up and sail 50 feet above the ground. The launch pad is a Swiss Family Robinson–style tree house in a huge banyan. From there you take off and soar past waterfalls and over the river until you reach a huge mango tree on the other side, then return toward the landing pad. Haviland's company, Outfitters Kauai, also leads kayaking, biking, and hiking trips all over the island. His favorite: the Kipu Falls Safari, which combines kayaking, zip line, rope swings, swimming, lunch, and a hayride (Poipu Plaza, 2827 Poipu Road, Koloa; 888-742-9887; www.outfitterskauai.com).
