The Alaka'i Swamp sits in the bottom of a 13-mile diameter caldera formed by the eruptions that created Kauai six million years ago. This caldera receives hundreds of inches of rain annually. Fewer alien plants have moved into this area where a wealth of native plants abound. The swamp's elevation above 4,000 feet is above most mosquitoes and is the last refuge for native birds who lack immunity to the bird diseases mosquitoes carry.
