Of all Kauaʻi’s unique wonders, none can touch Waimea Canyon for grandeur. Few would expect to find a gargantuan chasm of ancient lava rock, 10 miles long and over 3500ft deep. It's so spectacular that it has been popularly nicknamed the 'Grand Canyon of the Pacific.' Flowing through the canyon is Waimea River, Kauaʻi’s longest, fed by tributaries that bring reddish-brown waters from Alakaʻi Swamp’s mountaintop.
