30. Perito Moreno Glacier
> Location: Argentina
Unlike the glaciers on earth that are shrinking or disappearing, the Perito Moreno Glacier spans 121 square miles and is growing. A boat trip through Lake Argentino around the base of the glacier is the safest way to get close to the ice and witness its sheer mass.
31. Lake Hillier
> Location: Australia
Located on an island inaccessible to tourists, the bubblegum pink Lake Hillier is only viewable to the public by air. Though scientists haven’t confirmed the exact cause of the pink waters, they’re most likely due to a combination of high salinity, algae, and bacteria.
32. The Giant’s Causeway
> Location: Northern Ireland
Made of a patchwork of 40,000 interlocking basalt columns, the Giant’s Causeway is a volcanic formation over 50 million years old. The site, which has inspired many local legends, is an important geological zone for the study of volcanic activity during the Tertiary period.
33. Vaadhoo Island
> Location: Maldives
Bioluminescent phytoplankton in the waters around Vaadhoo Island create the illusion of a sea of blue stars lapping the shores at night. Though a handful of beaches across the globe are famous for their glowing phytoplankton, some consider the concentration of illuminated water around Vaadhoo the best display in the world.
