Camaderry, Mountain summit in County Wicklow, Ireland.

Camaderry is a 699-metre summit in the southern Wicklow Mountains that forms a broad horseshoe around the Glendalough valley together with Turlough Hill, Conavalla and Lugduff. It has a subsidiary south-east top at 677 metres, and its north face drops to the glacial corrie of Lough Nahanagan.

The Luganure mineral vein, carrying lead as galena with traces of silver, was worked on Camaderry; in 1859 the Glendasan and Glendalough mines were joined by adits driven through the mountain, most of which are now flooded. Mining ceased in 1957, and remains of the Miner's Village at Glendalough can still be seen.

The Irish name is Sliabh Céim an Doire, meaning 'step or pass of the oak-wood'. The neighbouring corrie lake is Loch na hOnchon, 'Lake of the Water Monster', and Irish folk-stories are attached to it. The cliffs of that corrie are climbed on single-pitch routes graded up to VS 4c.

Parking areas near Glendalough Lake and Wicklow Gap serve as starting points for different hiking routes to the summit. Weather can change quickly, so warm and waterproof clothing is advisable.

Lough Nahanagan, on Camaderry's north face, is a glacial corrie lake whose Irish name, Loch na hOnchon, means 'Lake of the Water Monster' and features in several Irish folk stories. The cliffs of its corrie are used by rock-climbers on single-pitch routes graded up to VS 4c.
