According to research, being in close proximity to water can help improve your mood, mental health, and creativity. Recently, travel experts at SIXT studied more than 50 of the country’s best bodies of water including hot springs, lakes, cenotes, and more. From that pool, they compiled their list of the top bluest waters across the country. Here are just a few of the locations that have ranked among the top bluest waters in the U.S.

“The world is full of stunning natural wonders, but there’s something unique about recharging while enjoying blue waters,” said David Woody, country development and travel expert at SIXT.
