Thank you for reaching out to us! It would depend on what you expect from a walking trail? From Banhoek Lodge there are 5 wine estates within walking distance and so guests enjoy doing wine tasting per foot. The closest farm being 500 meters and the furthest being 3.5 km.
Otherwise there is the Simonsberg which is open to the public for hiking and this starts at the private residence of Tokara. This is a 2.5 h walk each way and climing to 1399 meters.
There is also Helena who does guided hikes into different areas of Stellenbosch. Jonckershoek is another nature reserve from which you can walk to a waterfall (does not need to be guided). R50 entrance and 13 km from Banhoek Lodge is the starting point.
Let me know if this does not answer your questions?
Yes, a lovely walk through the vineyards.
