These trails are a combination of all sorts of riding challenges for all sorts of riders. While some parts run on fitness tracks suitable for beginners, there are also many challenging rock gardens which will raise a heartbeat even for an experienced rider. The 30km trail isn't marked as a whole, so you'll need to bring ome GPS to find your way around. Some parts of the trail are running on marked loops, but it always disconnects at some point.
