This ride is a fantastic ride and only for experienced riders. The ride starts at a trail head on Sand Flats Road which is followed by 5 kilometres climbing 300 metres. Not too bad you say but when there's a ledge every few metres it makes for a tough ride. An alternative is to keep driving up Sand Flats Road to the next trailhead which basically takes you up to the mesa rim.

Once you get up to the top, you get a massive view out over Porcupine Rim that is absolutely brilliant. This is followed by a 15 kilometre downhill run over rocks, ledges, boulders, etc. Best ride I have ever done. Have a look at the video to get an idea.

Heading down the Porcupine Rim Trail - didn't take many photos. Was having too much fun on this ride.
