The south face route of ORY is best approached from the east of the hillock. The GPS Coordinates (13.425901, 77.506034) would get you close to the Makalidurga Railway station and railway line which abuts the eastern flank of the hillock. Best you drop the gear and other folks at the railway tracks and drive a kilometer to park the car at Gunjur village, and hike back. From the railway tracks, to get to ORY route, it is about two km hike. From Gunjur village, the hike is about three km. The desolate parking lot at the railway tracks is known to invite break ins.
To approach the west cliffs of Makalidurga, you would have to approach from the west. On Doddaballapur-Gauribidanur road, after Doddaballapura, take the left at the petrol bunk with signage towards Green Valley Resorts (13.372044, 77.509449). Go past Green Valley Resorts and take the right towards Gundamagere lake. Go through the village, and there is a rutted road that drives left of the bund (raised lake embankment) and get closest you can to the west cliffs of Makalidurga (13.432508, 77.493148). The hike to the west cliff climbs is frequently overgrown. Take a machete along to clear the overgrown trail.
