There are yellow warning signs in Estonian, Russian and English before the entry to the border area, notifying that you are about to enter the Russian Federation and that walking and stopping is prohibited there. This is monitored by the fine border guards of both countries as well as cameras. It is, in fact, prohibited to get closer than 15 metres to the border post. If you wish to do so, you can take photos with the border posts at the yard of the Saatse Museum, where it is allowed and appropriate.
As of 2019, there are only three places in Setomaa where it is possible to cross the control line: Koidula and Luhamaa border points, which are open for traffic, and the Saatse border point, where the border can be crossed only on foot or by bicycle. And even this is allowed only for Estonian and Russian citizens.
