Today, underground caves deal with different sciences like archeology and medicine.
Because, caves give us information of the past.
They seem like a mysterious world enlightening us with underground movements, fossils, stalagmites and stalactites, plant and animal world of underground, geological knowledge, some chemical and physical knowledge hydrological and hydrogeological knowledges. Underground caves are like curing hospitals and laboratories because of the gases like carbon dioxide, oxygen, nitrogen and sulphur.
Also, mineral waters are very important for human health.
In the caves, it is possible to see and use the curing waters which cannot reach the surface.
For reaching Aslanlı Cave at Kirazlı Village, Yayla region, you have to leave the car at Derebogazı part of Kusadası-Kirazlı road and follow the 3 kms. jang soil-road on the left, on foot for half an hour; or for ten minutes by another kind of vehicle.
It is a partly perpendicular, partly horizontal type of cave, where the inhabitants know but cannot enter. The first examination was made by L. Nazik and N.Güldalı from İzmir project team of Mine Checking and Research [MTA] General Directorate, in December 1985.
GEOLOCICAL & GEOMORPHOLOGICAL STRUCTURE
It is a cave that developed inside of mezozoic age Dolomithic marbles on a big surface.
After a 6 m. long downward slope, the cave descends to the west with 26° angle, through a line which has east-west direction.
After 40 meters , it enlarges and looks like a slope-floor hall.
This part of the cave is covered with either muddy soil or big rock blocks which have fallen from the ceiling.
Also on this stack, stalagmites and stalactites have formed, and the wells were covered with curtains and flag-travertines.
It is called "Aslanlı (lion)Cave" because of the lion-like stalagmite. Hydrologically, it is a dry cave. The temperature of the cave is about 18-20 °C.
A large bat colony and other small animals have been seen here.
The cave is 110 m. long, 36 m. deep, and it is known as "Yaren [Friend] Cave" inhabitants.
Curing of asthma and chronic bronchitis with carbon dioxide, oxygen, nitrogen and radioactiveness of its hot and moist air, are possible only after touristic planning.
Though the end of 1994, the soil pathway to Yaren Cave was enlarged for large vehicles.
Inhabitants of Kirazlı, due to this situation, await the extension of the cave mouth mounting of a stairway, concrete path and stairway and illumination for sanitary tourism.
