Summary:
Don't think - oh it's only 13km - after negotiating lovely some singeltrack through cool (knyzna-type) forest area (fun), you start climbing on fire-road through pine-forest area - probably approx 5km of steady, never-ending, slow climbing. Once you reach the top it is easy coasting down old neglected fire-roads. Some downhill singletrack (technical) negotiation through pine-forests (fun) and a fast downhill back home. Don't expect to break your average speed records. Definatley worth it - I will be going back to do the blue, yellow and green.

Recommended Route:
You actually have a selection of 4 trails - blue, red, yellow or green. (I've only done the 13km red)
I suspect the blue is the shortest through to green being the longest - just check with reception at Merry Pebbles (Castle Rock).
Follow trail markers from the castle rock entrance. (a SAFCOL permit is required - obtainable at the Merry Pebbles reception - cost R20 pp and valid for a week.

Other recommended trails in the same area:
Enquire at the SAFCOL museum in SABI about various other trails: 1-5 day MTB trails are available.
