Worth the trek down to industrial town, even despite the odd hours, Grandmaket, or the Grand Model, is exactly that. The 800 square metre model of Russia from Petersburg to Kamchatka has been laid out in all its glory and intimate detail. Complete with vast forests and the peaks of the Urals, criss-crossed by railways and winding rivers, there are also motorized vehicles, scenes from village life and interactive buttons that allow you to do things like begin earthworks at a construction site. Way too much fun.
