Sally Ward Spring
A spring with a magnificent underwater cave system below it. The length of explored passages is 2,195 m.
Wakulla Spring
One of the most impressive cold water springs in the world, the diameter of this spring pool is 96 meters, its depth is 56.4 meters. One of the most powerful springs in the world, its discharge has reached up to 54,226 liters per second. The water coming out of it has formed a very extensive freshwater cave system.
Jinbar Falls (Jin Bahir Falls)
Jin Bahir stream falls into a giant, 800 m deep abyss in Simien Mountains. Falls are starting from deep canyon – thus their height is less than the depth of abyss but nevertheless – more than 500 m.
