Iceland's Sky Lagoon Is a Wellness Haven — Here's What to Pack For It

Andrea Iyamah Tiaca One Piece Swimsuit ($60, originally $185)

Of course, the most important thing to bring to Sky Lagoon is a bathing suit. You'll be popping in and out of cold pools and saunas, so I recommend something that's comfortable and easy to move around in, like this convertible swimsuit from Andrea Iyamah. And for even better photos, opt for something bright and vibrant like a sunny yellow shade — it contrasts beautifully against the lagoon's blue-gray and charcoal color palette.
