There are a handful of places within U.S. borders that offer the same aesthetic experience at a fraction of the price. Some of the country's most notable examples of ultra clear waters can be found stretching out over hundreds of miles along the Gulf coast of Florida (as seen above). Whether you prefer the vibrant atmosphere of Panhandle resort cities like Pensacola or the laid-back vibes of Siesta Key in southwestern Florida, there's no shortage of crystalline turquoise waves. Of course, white sand beaches aren't the only place you'll find these pristine waters. There are plenty of lakes, rivers and shorelines in the U.S. that boast surreal hues and astonishing visibility. And while some may be too chilly (or fragile) for swimming, here's just a few sigh-worthy destinations to add to your must-see list. Lake Tahoe — California/Nevada Lake Tahoe, Nevada. (Photo: topseller/Shutterstock) The water quality of Lake Tahoe is legendary. Upon visiting this body of water in the 1880s, Mark Twain wrote "the water was not merely transparent, but dazzlingly, brilliantly so." Unfortunately, this startling clear visibility is experiencing a decline due to an increase in fine sediments as well as excessive nitrogen and phosphorus levels from car emissions that are accelerating the growth of algae. As conservation group Keep Tahoe Blue explains, "consistent scientific measurements of water clarity started in 1968. At that point, one could see a white disk submerged to a depth of 100 feet. Today, clarity has dropped to around 70 feet. That means Tahoe is losing about one foot of clarity per year." Hanauma Bay — O'ahu, Hawai'i Hanauma Bay, Hawaii.

To preserve this natural treasure, local governments banded together in the '90s to establish it as a nature preserve and put restrictions on its daily use. While visitors are still welcome to swim and snorkel in the bay's waters six days of the week, they must not harass wildlife or disturb the expansive system of coral heads. Havasu Falls — Grand Canyon National Park, Arizona Havasu Falls, Arizona.

At the end of this sweltering trek lies Havasu Falls, a dramatic blue cascade with remarkably clear waters. Lake McDonald — Glacier National Park, Montana Lake McDonald, Montana.

Its chilly temperature and lack of nutrients are what makes the water so clear. According to the National Park Service, "the temperature [...] never gets above 50 degrees Fahrenheit at the surface, so plankton growth is minimal. It is not unusual to spot details on the bottom of lakes beyond 30 feet." Frio River — Texas Hill Country Frio River, Texas.

The name "Frio" means "cold" in Spanish, a nod to the river's chilly, spring-fed waters. The best way to enjoy a lazy float down the Frio is by visiting Garner State Park, the most popular state park in Texas. Hanging Lake — Glenwood Canyon, Colorado Hanging Lake, Colorado.

The lake, which sits along a fault line, was formed after nearly 2 acres of land collapsed into the Earth after intense geological activity. The gorgeous blue-green tint of the water is the result of dissolved carbonates and minerals from the surrounding travertine limestone. Jenny Lake — Grand Teton National Park, Wyoming Jenny Lake, Wyoming.

Although motor boats are permitted on the lake, a 2005 water quality survey revealed that Jenny Lake remains in virtually pristine condition. Planning a visit to Grand Teton and want to visit this glassy lake in person? You're in luck — it's the starting point for several popular day and overnight hikes within the park.
