Walking and hiking in Newlands Forest, in Cape Town, is a very popular activity. There are numerous trails to explore. The area is patrolled by both the Park Rangers and SA Police (road routes), and it is heavily used so you are usually not alone, and there is ample free and safe parking.
There are a number of geocaches also hidden along the various trails, so if that is your thing, be sure to plan ahead for this. This particular route takes about 45 minutes and has no steps. Be sure though to take water with you, and always inform someone where you intend to walk and when you expect to be back. There is cellphone coverage along the whole route.
The base itself also has a helipad landing area where the helicopters land while doing fire fighting duties on the mountain.
