Many people think so. A rare combination of geological features come together on Kauai. The Hawaiian islands are the most isolated specks of land on the planet,  2000 ocean miles from anywhere. Tradewinds blow across the Pacific, picking up water vapor as they go. Kauai’s central mountain, Mt. Waialeale, has the perfect funnel shape to cause the winds to swirl up in a vortex and drop their moisture.

The mountain’s summit is the wettest spot on earth, getting 400 to 500 inches of rainfall a year. The porous soils there capture most of this water like a giant sponge, making the Alakai Swamp the world’s highest swamp. All this water constantly drains, sculpting the fantastically shaped cliffs of the Na Pali, and sourcing myriad streams, rivers, and waterfalls.

While the rains are falling on the mountain, the lower lands and beaches, just a few miles away, remain mostly dry and sunny.

This proximity of wet uplands and dry lowlands yields a bonus: rainbows almost every day.

If you’re lucky, you can even see a moon rainbow. For a few days each month, the light of the full or nearly full moon can create rainbows in the night sky. (The moon will be almost full the last night of the conference, but no promises!)
