Sabie is a forestry station in the Mpumalanga province of South Africa.

• Bikers like to ride on the mountain passes (the world mountain-bike competition has been held here on at least one occasion)

With Sabie Backpackers:

• River-Tubing: ie, going down the river-rapids sitting in a hard rubber ring/tyre
• Caving: caving in the mud-caves by candlelight, DO NOT be tempted to do this without sabie backpakers as this is dangerous
• Bridge-Swing: ie, standing on the bridge at the bottom of town and jumping off (with a rope attatched of course so that you swing underneath the bridge tarzan-style and are then lowered down to the bottom for the short walk back up)
• Sabie Panorama: a tour of the surrounding views and sights to the north of Sabie including fantastic photo opportunities, waterfalls, the three rondavels and some souvenir stalls
• Paintballing
• Abseiling: including abseiling down a waterfall if you fancy something different
• Kloofing/Gorge walking: hopping between and on rocks down a river, under waterfalls etc etc...you will almost certainly get quite wet
• Mountainbiking
