The Crimean peninsula has many natural beauties and attractions dating back to various historical periods up to Antiquity. However, tourists are inspired not only by what can be seen on the Crimean land, but also by what is hidden in its depths: the Crimean caves open to their guests fantastic pictures of fairy-tale beauty.
There are more than 800 caves in Crimea, but one of the most remarkable among them is Kizil-Koba — the largest on the peninsula, one of the largest limestone caves in Europe.
Kizil-Koba cave is located in the mountain massif Dolgorukovskaya yayla 3 km from the village of Perevalnoye, which is located northwest of Alushta. Since 1963 it has been classified as a geological natural monument of national importance.
Kizil-Koba got its name because of the reddish hue of limestone, and it is translated from Turkic as «Red Cave». Often these caves are spoken about in the plural — Red Caves, because there are a lot of underground rooms, galleries and halls here, and together they form a complex 6-storey complex, a whole underground kingdom.
The beginning of scientific research of the Red Caves was laid by the local historian S.I. Zabnin in 1914. Since then, this fantastic world continues to be discovered, and to date, the length of the explored part of Kizil-Koba is already 25 kilometers!
It was discovered that in the caves themselves and in the glades near them lived people in the VII-VI centuries BC. Archaeologists found here a lot of household items and tools, bones of sacrificial animals — in those distant times the caves were a family sanctuary of ancient people. At the beginning of our era, wine was stored in the caves, and there was a Scythian farmstead in the glade. 
Because of such important discoveries the Red Caves were also awarded the title of archaeological monument, so it will be interesting to visit here not only for connoisseurs of amazing natural pictures, but also for those who are attracted by places where ancient people lived.
The red caves in the depths of the mountain massif were formed by the underground river Kizilkobinka, whose waters ran through cracks and faults in the limestone for thousands of years. Even today the river flows through the first floor of Kizil-Koba, and going outside to the daylight, forms a beautiful vodopad Su-Uchkhan, coming off a high cliff.
The caverns are decorated with stalactites, stalagmites, corallites, carbonate concretions, columns, and draperies. Among the many halls stand out Chinese, Indian with openwork tincture decoration, Academic, Gryphon, Pigeon Cave, and the largest among the explored underground rooms — the Hall of Blue Drop, in height it is 145 meters. Many halls are impressive in their scale, reaching 70-80 meters in length and 30-40 in height. Even more impressive are the underground lakes and waterfalls formed by the waters of Su-Uchang. In some places, you can also find underground pearls in stone tubs with crystal clear water.
The equipped excursion route through the Red Caves is 500 meters long and ends near the first karst siphon — 
corridor flooded with water and separating the room from the next halls, which can be accessed by everyone, but with special equipment. For extreme lovers such a walk will be a real treasure trove of impressions. But all those who have visited only the equipped part of the route will have not much less: the cave opens its guests amazing, fantastic pictures.
All those who visited this attraction of Alushta speak about it with great delight. The Kizil-Koba cave has long been talked about as the most interesting attractions of Crimea, the most beautiful place where you can see how rich and inexhaustible is the imagination of nature.
