For road bikers, the Clarens to Fouriesberg route is particularly scenic and there is a wide shoulder. Some nice flowing bends and steady climbs plus fairly quiet.
The route from Clarens to Golden Gate is a fantastic fast ride of about 30 kms but do it when the traffic is minimal as the shoulder is not wide or even non existent which is not fun. To make it interesting, take the Blesbok and Oribi loops in Golden Gate which makes the ride about 80 plus kms. Golden Gate trails are good for climbing and wind training. One rider did the Clarens to Golden Gate entrance … 60.8 kms in 2.30.10 with a headwind all the way back. Think that is called flying!
A challenging and very scenic ride is by MTB from Clarens to Calendonspoort border post. Do this in a group. You can mountain bike midway between Clarens and Golden Gate, up the dirt road to Bokpoort game farm and on to Rebellie game farm and then up the 4×4 trail to the top of the hills overlooking the Caledon river. From there you can take the trail to Camelroc, quite technical and the climb to the top is tough to near the Calendonspoort border post with Lesotho. Maybe tough but the 30 km trail is a very rewarding experience.
Another good ride is out of Clarens on MTB towards Bethlehem and just after the top of the climb turn right onto a dirt road that has a wooden sign that says “Toeka” – Ride it for plus minus 15-20 kms and and take a right turn. T junction right again and follow that road – it will eventually come out on the other side of the Golden Gate park.
Bokpoort Game Farm has good blue trails and it is just a 15 km ride out of Clarens.
