Lake Retba, Senegal or as the French refer to it Lac Rose, is pinker than any milkshake you’ve ever come face to straw with. Experts say the lake gives off its pink hue due to cyanobacteria, a harmless halophilic bacteria found in the water. Lake Retba also has a high salt content, much like that of the Dead Sea, allowing people to float effortlessly in the massive pink water.
As manatees can't survive in water below 60 degrees, they migrate to Kings Bay and the adjacent rivers every winter, which are an average 72 degrees all year round. So from November through March 2012, you can head to Crystal River, which is 70 miles north of Tampa, where it is the epicenter of manatee-watching, and go frolicking with these giant but affectionate creatures.
