On the 60th parallel north, the city of Saint Petersburg is below the Arctic Circle, but not by much. This location allows it to enjoy, around the June 21st summer solstice, very short nights.
A diffuse light remains around the clock as the sun barely slips below the horizon. After the long, cold, and snowy winter, and the short spring, the White Nights reawaken the population in every street of Saint Petersburg. Everything is a reason to go out and sit at cafes, stroll along the banks of the Neva River, or attend one of the many festivals or other artistic events that regularly take place. On the river, lift bridges open up to let ships back in again.
Every night, the city comes alive. This period, which lasts from late May to mid-July, is very popular with tourists who revel in this joyful atmosphere, so book your hotel and theatre tickets well in advance.
