No special access issues
The easiest way to get to this crag is with a personal vehicle. The last few kilometers of the road are unpaved. The road is slow going but not particularly difficult. Only if your car has very low ground clearance you might want to consider leaving the car where the pavement ends and hitching a ride as rocks might damage the bottom of your car.
APPROACH (see the gps trail on the map as well)
From the restaurant by the parking marker on the map, walk back down the gravel road. After some meters there is an option to go left on to a path behind some houses (this is a shortcut for a big bend in the gravel road). When the path meets the road again (at a switchback) continue straight on a trail along the edge of a field. When reaching the end of the field turn left, again walking more or less parallel to the edge of the field. From here follow the faint trail/goat tracks around the corner to your right and in a few minutes you will reach the Guri Radanis Sector.
For Koligramshia: continue along the base of the of the Guri Radanis sector, nearly to its end. From there make your way down the hill following a trail. There's a few different options; if you lose the trail, you can aim for the electricity pole at the bottom of the little valley. From the electricity pole follow the, now more clearly visible, trail down the valley and around the corner. After coming around the corner you will quickly reach the sector.
