There is no beach in front of Mariposa and there never will be as long as that sea wall remains in place. That's because the retaurant at Mariposa encroaches on the natural shoreline. Such is also the case for; The Boat Bar and the gift shop there, Tony's Hut, Lazy Dayz, The bar at Tree House and the Gazebo at Tree House.
When structures encroach on the natural shoreline, they cause errosion. Just look at the sand that has been carved out in front of the Tree House Bar, it is getting almost impossible to walk around it when the tide is up.
Every time I have to detour through the bar at Tree House, and walk in the water around the other structures that jut into the sea (which is several times a day when I'm in Negril) I wonder why they are allowed to remain there - well, I guess I know: $$$
