At the end of the Playa Esmeralda road is this self-guided hike, which, at USD$3 for 1km, is quite possibly Cuba's most expensive trail. Walk slowly to get your money's worth! The marked route (with several more kilometers of bushwhacking on fire trails leading to a picturesque bluff with a lighthouse) apparently has 14 endemic plant species. Inauthentic sculptures of indigenous Taínos guard the route.
The bluff was originally touted for hotel development but was saved from the bulldozers by government intervention. A model at the start shows what the hotel would have looked like.
