Dunn's River Falls Jamaica closeup Key Ring

Dunn's River Falls is a famous waterfall near Ocho Rios, Jamaica. It is one of the very few travertine waterfalls in the world that empties directly into the sea. Described as a living and growing phenomenon, it continuously regenerates itself from deposits of travertine rock, the result of precipitation of calcium carbonate from the river, as it flows over the falls. The small dome-shaped cataracts are usually associated with thermal spring activity found in limestone caves. This, combined with its location near to the sea, gives Dunn's River the distinction of being the only one of its kind in the Caribbean, if not the world.
