We used the beach for a couple of hours on a day trip to Port Antonio out of Ocho Rios. And what a stunning beach it is!
The beach is fairly small but spectacularly scenic, hemmed in between rocky shores. A lazy clean river with lots of fish empties at the beach in the sea, and you can actually choose to swim/be in the river part with calm water to which the beach extends, or in the sea water which is a bit turbulent with fairly high waves. Our small children preferred the calm river water where they could also observe the fishes, and where there was also plenty of shallow water to frolic around in.
The beach has a restaurant with service on the beach, and toilets, showers and changing facilities.
Entrance fee is expensive, $8 US for adults (half for children 4-12), but if you have a couple of hours to spend it's worth it.
