Here's a site with some great touristy type pictures of Kauai: Kauai Image Galleries.

There's even a picture of Salt Pond, which is one of my favorite beaches near where I grew up. It's an enclosed pond, so you dont' have to worry about riptides when you swim. It was a favorite party beach when I was high school. One night my friends and I had a drunken moonlight swim, and then afterwards we laid on the beach in hopes of getting a "moon tan".
