KARST formations - works of #geology & works of art. Limestone uplifted from the sea is sculpted for millions of years by water, wind & chemical reactions. Erosion is augmented in the tropics by heat, humidity & vegetation. A classic karst wonderland: #Vietnam’s Ha Long Bay. 
Below are some other karsts I’ve known and loved.
Clockwise from upper L:
Andaman Sea near Krabi, #Thailand
Yangshuo near #Guilin, China
Vang Vieng in #Laos.
Coron coast and bay in the #Philippines,
Viñales Valley in #Cuba (where the karst outcroppings are called 'mogotes')

Another karst wonderland, with a bonus: the area around Puerto Princesa on beautiful Palawan in the #Philippines. Over 5 mi of the Cabayugan River runs through a giant karst cave, much of it navigable by boat from the entry on the turquoise West Philippine Sea. A natural wonder.
