"Waimea Canyon Often described as the Grand Canyon of the Pacific, this 10-mile-long Kauai valley is a kaleidoscopic array of scarlet earth, verdant valleys, and raw volcanic crags. Bands of color streak the corrugated landscape, each representing a different eruption and layer of lava. Waimea Canyon Drive has a series of lookouts; among the most popular is Waimea Canyon (past the Mile 10 marker on Highway 550), where a number of rivers once cascaded down the gently sloping shield volcano. When part of its flank collapsed, the rivers combined with dramatic results. Continue into the mountains to explore Koke'e State Park beyond. Its small, free museum contains a 3-D map, which sheds light on the canyon's wild beauty, while the gift shop specializes in local art, crafts, and Niihau shell jewelry."
