Harrison Cave is one of Barbados most famous landmarks. It has been known about the cave since the 18th century, however, several expeditions, which went to the central mountainous part of the island, could not find and explore it. The cave remained an unsolved mystery until 1970. Danish caver Ole Sorensen, at the invitation of the Barbados National Foundation, along with Tony Mason and Ellison Thornill began exploring the cave. They were faced with the task of conducting a survey, mapping the cave and assessing its potential. Since 1974, the government of Barbados has been initiating and financing the improvement of the cave in order to attract tourists. The cave was opened to the public in 1981. Entrance to the cave begins with the Noel Boyce Tunnel, one of the pioneers of the construction team. On a sightseeing tram, visitors drive through an extensive cave system to the lowest point of its level. Here you can get out of the tram and go to the amazingly beautiful waterfall that fills the underground lake with clear water. The cave is at least 2.3 km long. On the route of the tourist tram, the galleries of stalactites and stalagmites succeed each other. By geological standards, the growth of stalagmites in a cave is considered to be very fast - every year they add in growth "by the thickness of a sheet of paper." The largest hall is about 15 meters high. The Harrison Cave tourist center has professional guides who conduct not only fascinating tours of the cave, but also accompany tourists on an eco-adventure tour of the inaccessible paths of the area and the labyrinths of the cave left untouched by man. The center has souvenir shops, an exhibition of artifacts found by archaeologists in Barbados, and restaurants and bars.
