|North Shore Kauai|
Bottom left of upper photo is the Wahina River, which drains the valley where the last of Hawaii's ancient people, the Menehune where counted in a 20th-century census. From there, the highway twists through a tropical arboretum, passing Lumahai Beach (of South Pacific fame), and reaching Haena State Park—site of beach-side camping and near Tunnels snorkeling beach. The Kalalau Trail along the Napali Coast starts a couple miles past Haena, where the highway ends.
Helicoptering over Kauai will give you the best perspective of the island's dramatic beauty. Blue Hawaiian helicopters is a good choice. When it's time to test the trails, the Kauai Trailblazer should be in your daypack.
