Deep Sky Rainbow
Tunnels Beach - in the image - is the quintessential snorkeling beach in Kauai. It receives a lot of visitors during the day, and it's not unusual to still see 3-4 cars parked there at night, so it's not the best beach if you want solitude at night. Since it's in the north coast, you do need a bit of luck to get a clear night. The peak in the back is Mount Makana, also known as Bali Ha’i.
