We spent a couple of hours hiking on a 'medium' route at Mont Rochelle Nature Reserve. It's a few miles north of Franschoek up the pass. You need to have a ticket first before you start one of the trails, these can be bought at the main Tourist Info Office in the centre of Franschoek. Some of the trails are quite tough, so you do need decent hiking footwear, water and sunscreen. Some of the views are brilliant, and well worth the effort of the steady climbing.
