From 10th to 14th of June in the region of Kaluga the legendary open-air festival of free art “Pustie Holmi” (Hollow Hills) took place. This unusual and colorful festival was held for the traditional eighth time. We present you pictures from the festival, which were taken by photo-blogger Ilya Melnikov. Enjoy watching these amazing photos that will take you to a journey of love, music and nature. This festival looks to me like a hippie commune a little bit, but it still seems great nevertheless!
