Lonely Planet has described the valley as the most beautiful in South East Queensland.
Compared to other areas of the Gold Coast the Numinbah Valley has remained largely undeveloped in recent decades. To the east is the Springbrook plateau. On the eastern side of the valley is the Natural Bridge in Springbrook National Park and to the west lies the Lamington Plateau and the Lamington National Park. To the south is the Tweed Valley in northern New South Wales.
