Moorea, Tahiti

Snorkeling in Tahiti means walking 20 yards from your grass hut, getting into the water at 8:45 a.m., to a depth of barely floating and seeing dozens of gorgeous fish.

Tenaya Lake, Yosemite

I literally grew up in campsites here. My family and I went to Tenaya Lake for car camping every summer from the time I was about 8. Stunningly beautiful and stunningly COLD!

Eleuthera, Bahamas

Here's where I snorkeled for the first time (choppy sea removed my fins as soon as I jumped in), fell in love with the Caribbean, and learned to appreciate pink sand.

Turks and Caicos, British West Indies

Turks had the best seashell beach I've ever laid toes on. While learning to scuba dive, I got goosed by JoJo, the resident dolphin. Won a medal for friendliest snorkeler. Made some wonderful friends and got hardly any sleep the entire week. Well worth it.
