Kauai Museum
A small two-building museum in Lihue covering the natural and cultural history of Kauai and Niihau, from the islands volcanic formation to the sugar plantation era. Kids respond to the koa wood canoes, feather work, and the shell lei from Niihau. A relief map of the island helps explain why the interior is impassable and why the Napali coast looks like that. It is genuinely small, about an hour, which makes it a reasonable stop when a Kauai downpour parks itself over the island. Gift shop has good local crafts.
