There are strict regulations in force by the Russian border police which you must adhere to otherwise you will be arrested. You don't require a visa to enter this pocket of Russia but once you enter the forest gate you must travel along the 900m stretch of road at no less than 60km/h and you must not stop. Pedestrians and cyclists are not permitted, you can only travel by car.
Once you arrive in Saatse you will find a Setu museum and perhaps see one of the village's 89 inhabitants.
In 2005 the Estonian and Russian governments approved a new border treaty which is yet to be ratified. Small pockets of land will be exchanged in order to make the area through which the road passes Estonian territory.
