There are 3 ridge routes starting off the Peoples Path beyond the turnoff to the old Woodhead tunnel entrance at Hell's Gates.

Continue up Disa Gorge towards the Woodhead Dam wall and 3rd Ridge is the least distinct of the 3 and starts up bushy slope beyond Dingaans Ridge. Grade is A with easy scrambling.
Unfortunately the way up has become overgrown through disuse. At the top head diagonally over towards a large beacon that may be visible, on the end of the Wynberg caves ridge.
