Horizontal Cave
150 m
-159 m
6650 m


Location: It is located 4 km northwest of the Oymapinar Village in the Oymapinar Dam area of the Manavgat District of Antalya. It was revealed when a natural gallery was found in one of the injection galleries during the studies carried out for dam.
Structural Properties and formation : It was formed within the Miocene conglomerate. It is partly conglomerate; and partly limestone. It is an active cave which developed horizontally with a length of about 7 km. The increased water level in the cave in spring may prevent explorations. The ponds inside the cave have different elevations. There are differences in the water levels between summer and winter (ranging from 68 m to 128 m). It was observed that in winter there was a flow of 12 cubic meters/second through the entry tunnel [Chabert et al. 1978b:4-9].
Research History: It was first explored by T. Aygen together with the French Paris Speleology Club President C. Chabert; J. Chabert; E. Gilli; J. Vuillemin; and two Turkish speleologists; M. Aktar and N. Aral in August 1976. It was mapped by C. Chabert and E. Gilli to the BCRA 5b standards in 1976. Another exploration on 20 August 2003 was made by E. Gilli and his team from France along with other cavers from BUMAK. It was observed by E. Gilli that some galleries which were formed in the conglomerate following the entrance have changed by corrosion even in this short period of time. One of the most interesting findings is a few kilometers far from the entrance; in the "Hall of Castles" where the floor is completely covered with sand. Four small sand castles; built by the members of the Speleo Club de Paris during their camping in the cave in 1977 and for which the hall was named after; were still intact 27 years later. The cave almost maintains its condition as it was found. It was stated that the cave should have been visited by very few or very caring cavers during those years although it is very close to Side; a very touristic area.
