Maralnik Bloom Festival in Biryuzovaya Katun
The Maralnik Bloom Festival marks the moment Altai's hillsides flush pink-lilac each spring, as maralnik, a wild rhododendron nicknamed Siberia's cherry blossom, bursts into flower around the Biryuzovaya Katun resort zone. Now in its second decade, the roughly May Day event has drawn crowds of 40,000 or more for guided excursions to blooming groves, open-air concerts, craft fairs and outdoor games marking the start of Altai's tourist season.
For about two weeks each spring, the hills around the Biryuzovaya Katun tourism zone in the Altai foothills turn a color that looks almost unnatural against the surrounding pine and rock: a soft, saturated pink-lilac, produced by maralnik, a wild rhododendron whose short flowering window has slowly become one of the more anticipated natural events on the Siberian calendar.
