On https://thescribsandnibs.com/africa/south-africa/garden-route/robberg-nature-reserve-hikes/ there are some photos of the walkway on Trail no.1 - note there is no guardrail plus uneven surfaces. Sticking to paved areas might be safer in your case.

Definitely still worth a visit.

Just walk as far as you can then turn around.

Amazing views along the coast line. Lots of seating by the car parking area and also some seats along the pathways especially near the start.

From what I remember it can get busy with locals early morning as they walk that area regularly, but we stayed during the Christmas period.

It’s a beautiful area.

Thank you to everyone for your thoughts and the links. We are driving from Cape Town to Port Alfred with many stops in between, but have three nights in the Knysna/Plettenberg area, so wanted to be able to find places to visit in that area.

Thank you all again!

Before reaching Knysna proper, you could take the turnoff to Belvedere and visit the tiny stone church at Belvedere, it is quite historic and has a Stations of the Cross meditation garden laid out around the property, if that would interest you. Travelling further up the hill is a great viewpoint over the greater Knysna area. Up and over the top of the ridge, the road will bring you to Brenton on Sea, that has 2 restaurants and unobstructed views over the ocean and a beautiful beach that stretches 6 km all the way to Buffalo Bay. Brenton Blu restaurant is truly memorable.

Having just walked the short and the medium route yesterday I would suggest that even the short route will be challenging unless you have full mobility. There is a great view point from the car park and picnic benches behind the drinks stall and a relatively easy walk up from the drinks stall to the top of the cliff, but beyond that it would be challenging! It is an amazing place though, with awesome views, one of the best we’ve ever done!

Thank you so much for this information. It sounds just the sort of thing we would enjoy!
