A little over an hour east of Negril you'll find the increasingly popular tourist destination, YS Falls. Locals will tell you that 25 years ago you could have come here to enjoy the cascading falls with only the help of a guide. Nowadays, the search for the almighty dollar has turned it into an attraction in nearly every packaged tour you'll find. Such ubiquity makes us wary.
The good news about YS Falls is that they're easy to find, there are clean, functioning bathrooms, and there are even five ziplines through the forest and above the falls if you're feeling up to a spike in adrenaline. Then again, any sense of solitude and commune with a natural wonder of the world will be immediately dispelled by the dozen others seeking out the same with their kids. Sorry, but this is what Jamaica has become.
Most tour companies also provide boat rides further up the Black River, where the highlight of the trip will be the crocodiles and the other unique plant and animal life that thrives in the mangrove swamps. Just try to seek out a way to see it without being whisked off to a more contrived attraction before you've had a chance to enjoy it.
