Two watercourses named Hidden and Finches Creeks flow to the east out of the reserve. It was dedicated as a Flora Reserve in 1963. Flora Reserve is the highest protected status for forest areas in the Australian National Parks system. Prior to 1963 the area was classified as a Forest Reserve. The fringes of the reserve were logged for red cedar, hoop pine and white beech. Bullock teams were used to drag out the logs. The reserve is composed of virgin old growth sub-tropical rain forest and hardwood species - flooded gum, tallowwood, ironbark and white mahogany.
The reserve has no formed walking tracks. It has no public access except through Lamington National Park in Queensland. On the NSW side of the border it is bounded by private landholdings. It includes an area of escarpment rising to over 1000 metres that forms part of the Queensland/NSW border. It is intended to be a place where the flora and fauna are free from interference from humans, domestic animals and feral pests.
