Discover the stunning Ak-Sai Canyons, where yellow-red sandstone cliffs and ancient riverbeds create a surreal landscape in Kyrgyzstan.
The Ak-Sai Canyons, located on the southern shore of Issyk-Kul Lake near the village of Ak-Sai, are a breathtaking natural masterpiece. Known as the “Valley of Forgotten Rivers,” this area is famous for its yellow-red sandstone cliffs and dried-up riverbeds hidden among ancient rock formations. Just 16 km from the village of Bokonbaevo, the canyons are a must-visit for travelers seeking dramatic landscapes and serene beauty.
The Ak-Sai Canyons cover an area of over 15 km², featuring hidden trails and remote sections. The canyon walls rise to an altitude of 1,750 meters, offering panoramic views of the valley and Issyk-Kul Lake. Over millions of years, erosion has sculpted the sandstone into incredible shapes and patterns, creating a landscape that resembles an architectural marvel. The yellow-orange cliffs, set against the backdrop of the Terskey Ala-Too Mountains, evoke a sense of grandeur and tranquility.
The name “Ak-Sai” translates to “White Valley,” a reference to the rivers that once flowed through the area. Local legends speak of ancestral spirits guarding the canyon and a giant who shaped the rocks with his hands. Other tales tell of nomads who used the canyons as a refuge from enemies and a place to worship nature. These stories add a layer of mystique to the already captivating landscape.
The canyons are situated at an altitude of 1,750 meters above sea level. The region experiences a sharply continental climate, with hot summers (+20 to +30°C) and cool winters. The best time to visit is June to September, when the weather is warm and ideal for hiking. Spring and autumn are also pleasant, though cooler.
The final stretch to the canyons is a dirt road, so a 4x4 vehicle is recommended.
