However, you can see most of the famous sites by strolling along the 5km (3 miles) of Nevsky prospekt, from the Admiralty to Anichkov Bridge, and making small detours along the way. Along the way, you'll pass the some of the most outstanding neoclassical buildings in St Petersburg and a series of stately churches and cathedrals.

Numerous small operators run tours along the river and canals, visiting famous sights like the Church on Spilled Blood and the bridge linking the Hermitage and Hermitage theatre, but only Angloturismo (tel: (921) 989 4722) runs tours in English. The best tours start from the Griboedova canal and boats leave as soon as there are enough passengers.
