This cenote (Spanish for "natural sinkhole") is the result of a collapsed limestone bedrock which created one big, beautiful, blue hole in the ground. 130 feet deep and 85 feet below ground level, take your time as you wind down the carved-out steps — then feel free to dive right in.
Grotta della Poesia: Roca Vecchia, Italy

A past bathing spot of legendary muses, these limestone pools are as inspiring as they are gorgeous. The Grotta della Poesia (Caves of Poetry) are located quite far east on Adriatic coast of Apulia in Southern Italy, closest to the city of Lecce, making them quite the hidden discovery.
Las Grietas: Puerto Ayora, Ecuador

In Spanish, Las Grietas translates to creases or cracks. Get it? Take a swim in this natural earth fracture (which created these cool, blue waters) with no ocean in sight.
Sliding Rock: North Carolina, United States
Although not as crystal clear and aqua blue as the other options on this list, this pool is also a ride! Slip and slide your way down this smooth rock into the water below. Pay $30 for a day-trip to the local water park? No way. Just go here. A few side notes: be sure you know how to swim, and children under 7 should slide with an adult. Play safe!
Fairy Pools: Isle of Skye, Scotland


Located at the base of the Black Cuillins mountain range, and stemming from the River Brittle (in the Isles of Skye), the hike through the mountains is almost just as beautiful as the fairy pools themselves. If you're brave enough, immerse yourself in these cold, magical pools ... or just take in those breathtaking views.

Leave it to a volcanic rock formation to create this epically beautiful, tranquil body of water. Located on the coastline, let yourself be enchanted by the water that sprays over the rocks as tides from the coast crash in. Inaccessible by car, you'll have to let your feet take you there.
