Ayvaini Cave, Natural cave system in Nilüfer, Turkey
The cave extends for 4.86 kilometers through the limestone formations, featuring two separate entrances at Ayvaköy and Doğanalan villages.
Spanish speleologists discovered the cave system in 1970, leading to subsequent scientific studies of its geological composition and water patterns.
Local residents of Ayvaköy village maintain traditional connections to the cave, which influences regional folklore and natural heritage preservation efforts.
The cave requires specialized equipment for exploration, with the upper entrance beginning with a 17-meter descent into the underground network.
The cave contains 60 natural pools measuring up to 4 meters deep, with water levels changing according to seasonal snowmelt patterns.
