Entering Kalat the main road passes through a long tunnel then crosses a bridge shortly before the savari and bus stands. If you double back on the north side of the river and follow it 500m southwest you'll see this iconic, round mud-brick tower rising on the rocks above. Just beyond is the Katibeh Nader, an unfinished inscription on a smoothed section of cliff-face praising Nader Shah with poetry in Turkish and Farsi.
Climb to various rocky outcrops for views across the Darban village area, ringed by bright-red laterite slopes.
