Swimming holes are great because they are not only typically a hot spot for adventure activities – like snorkeling and scuba diving – but they also make for excellent travel photos with their telltale bright blue water. Luckily, to find a stunning swimming hole, there is no need to catch a long-haul flight to Hawaii (but if you do, here are some of the best swimming holes in the Aloha State). Instead, you can head to Florida, where you will find lesser-known but equally beautiful swimming holes – like Devil’s Den.
