[5][6] Camaderry has a subsidiary summit, Camaderry South East Top 677 metres (2,221 ft), and both lie across the deep Wicklow Gap from Tonelagee 817 metres (2,680 ft), which sits on the "central spine" of the Wicklow range.

[5][6] Between the north face of Camaderry and the east face of Turlough Hill lies Lough Nahanagan (Irish: Loch na hOnchon, meaning 'Lake of the Water Monster'), a deep corrie lake carved by a glacier at the end of the last ice age.

[8] The cliffs of the corrie around Lough Nahanagan are used by rock-climbers with single-pitch graded routes of up to VS 4c.

[9] Camaderry mountain contains the Luganure mineral vein which is a source of lead in the form of galena (PbS), and also contains traces of silver.

[10] In 1859 the Glendasan and Glendalough mines were connected with each other by a series of tunnels called adits, which are now mostly flooded, through the mountain.
