Here are a network of trails which you can walk/run. It is fairly flat and well marked. One of the routes is along the Pienaars River, birders will love this section. Your dog is also welcome. This place is popular, you can even go on your own.
This venue is also popular among mountain bikers. They do have mountain bikes for rent.
Directions: Travel east on Lynnwood Rd. Turn left in Silverlakes Rd and keep straight. After you passed the Silver lakes entrance, the road turns right. It becomes a gravel road which takes you into the parking area.
It is open 7 days a week and during weekends the Cowhouse Market is open. This is something different to experience.
Visit the website to see the different entrance fees. This is an affordable venue. Their system is cashless.
I have been there several times and have had fun and enjoyed the outing.
