The state-owned enterprise "Lensvet," responsible for lighting in St. Petersburg, has developed ten walking routes for tourists to enjoy the city after sunset. All of them are marked on an interactive map posted on the organization's website.
The routes primarily run through central St. Petersburg, covering its main landmarks, which look especially spectacular in the evening thanks to their illuminated lighting. To use the map, simply select a route number. For travelers' convenience, distances and travel times are provided along the entire route. Each point along the route is also provided with a detailed description.
