The Ületammi cliff, better known as the Risbieter's cliff thanks to the film The Last Relic (1969), is a sandstone outcrop in the Ahja River Primeval Valley Nature Protection Area, on the Taevaskoja–Otteni–Taevaskoja hiking trail. The murder of Hans von Risbieter was filmed in this place. To the west of the cliff is the Otten's Bridge, which was also used for filming.

It is possible to grill and make a fire at the Otten's campfire site near the Ületammi clfif. Camping is also allowed there.
