Take a Boat Ride down the Negril RiverTake one evening to skip the usual beach sunset. Instead, hop on a guided glass-bottom boat and ride down the Negril River. You'll start where the river meets the sea on the edge of Seven Mile beach, and cruise down its banks. Take in the gorgeous scenery of mangroves and birds flying against a yellow sky. The ride lasts about an hour and you'll likely be the only one there, away from the clamor of tourists.
