I previously blogged about the Harkerville Red Route which is certainly the most spectacular MTB route I have ever experienced. The Green Route is an easier option starting and finishing at the same point.
Where: Garden of Eden on the N2 between Knysna and Plettenberg Bay
Difficulty: the majority of the route is on easy forestry roads; just the last couple of kilometers where the route joins the Red Route are on single-track.
Cost: R38 permit from SANParks
All the routes in the Harkerville Forest are well sign-posted and easy to follow.
If you are looking for a slightly more challenging workout combine this route with the Blue or Yellow Route.
