If you are coming on foot you should find your way to the Tamula bridge. You can find this place on the map in the upper part, under the text which says "Tartu 65 km".
If you are coming by car then you should go to Valga highway. If you are coming from Valga then take a left turn to Roosisaare at the place where the sign says: "Roosisaare 5 km". The road will take you right to Kuningatalu.
If you are coming from Tartu or Põlva then you should go through Võru town and head to Valga highway. Fr.R.Kreutzwaldi street will take you to the railroad tracks. When you pass the railroad take a right turn and go out of Võru town. Right after the border of the town there will be a right turn and a sign stating "Roosisaare 5 km". This road will take you to Kuningatalu.
