Having done the North and Southern sections of the (near) Pentlands, I was left with Hare Hill, Black Hill and Bell's Hill to do.
I started again from Silverburn, but level with the quarry I headed L on a track which joins the "Red Road" near the bottom of Eight Mile burn

The track heading L below Black Hill South is not shown on the map

The row of mature beeches beside the track were not yet in leaf

Looking directly across to my first objective Hare Hill, there is an obvious track leading to the summit: I headed straight for it crossing the footpath that leads down past the waterfalls: this area at the head of the Logan burn is drained by a fan shaped series of ditches, and found the going quite dry

I walked easily down grassy slopes with a final steep descent into Green Cleugh, crossed the Cleugh, climbed the track up the other side towards Harlaw - and branched off R just before the stile . The track climbed steeply for about 25m and then levelled off beside a fence heading roughly E . I came to an open gate and headed L up a narrow footpath through the heather which climbed gradually NE to join the big landrover track that climbs this hill. A very painless ascent

I stopped briefly at the insignificant flat summit - not even worth taking a photo - and continued down the big track that led on towards Bell's Hill. After a hundred metres or so I took a couple of pics

The track descended into Den Cleugh (I seem to be there every weekend ) and I climbed the familiar track to Bell's Hill

Harbour Hill: I found that there was a direct track to the head of Maiden Cleugh:

I took the "bypass" track - it's fine in the dry - and followed the familiar route to the "corner of Bonaly woods
The path heads north beside the woods surrounding Bonaly Reservoir
