Characteristics
Oylat Cave was formed on a significant, east-west oriented fault line in the marble formation dating back to around 3 Ma. It is situated at the end of the Oylat Creek Canyon in a terrain of the Pliocene period. Fossils have been found in the cave.[1][3]
The cave's main entrance is 5–6 m (16–20 ft) above the canyon floor, where at this place the canyon walls rise up 450–500 m (1,480–1,640 ft) high. There exist three more entrances high above the cave's main entrance.[1] The cave has two interconnected levels, and has a meandering shape.[3]
Discovered in 2004, the cave has an overall length of 730 m (2,400 ft) with a 93 m (305 ft) clearance. The stalactites and stalagmites in the cave are colorful. It has a rich natural ecosystem, and is inhabitad by bats, butterflies, worms and guanobites.[3]
A large chamber is reached following a narrow gallery of 2–5 m (6.6–16.4 ft) width and around 15 m (49 ft) height after entry to the first floor cave. The chamber is occupied by dripstone ponds and gravel yards. The cave above is 25–55 m (82–180 ft) wide and 3–15 m (9.8–49.2 ft) high. It is composed of large blocks, pillars, stalactites and stalagmites as well as gravel, sand and clay layers.[3][4]
The meteorological conditions inside the cave vary according to the location. Narrow galleries and gateways connecting chambers and floors are somewhat windy. At an outside temperature of 29 °C (84 °F) and a humidity of 47%, the temperature falls to 19 °C (66 °F) and the humidity rises to 55% in the cave entrance. In the narrow gallery, the temperature decreases to 17 °C (63 °F) while the humidity goes up to 78%. Finally in the chamber, the temperature is at its lowest value of 14 °C (57 °F) and the humidity reaches 90%.[3][4]
Tourism
Located in a spa resort, the cave was opened to tourism in 2006. It is believed that the cave is capable of curing respiratory complaints, such as asthma and bronchitis. The cave is visited by domestic and foreign tourists. While domestic tourists come all around the year, foreign tourists, mostly from Kuwait and the United Arab Emirates, visit the cave during the summer season, between June and October.
Only 650 m (2,130 ft) of the cave is open to the public. Visiting the cave takes about 90 minutes.[3]
