Ewan McGregor eat your heart out. I spent a day with Bundu and it is one of the most amazing trips I have been on. Very informal, but safety concious from the outset.
All the equipment you could need was provided, a safety breifing detailing the proposed route and a bike familiarising session.
Then it was out onto the road for a short trip on tarmac before the real riding started. We were led out by Steve, who always kept his eye on the four of us visitors and followed by Tim in the support truck. We had numerous stops for refreshments and photo opportunities during the morning before stopping at Angies G spot for lunch. This was a real gem, aptly named by Angie as a Great spot (I know what you were thinking). After this it was on to more riding over some of the great passes in South Africa including Prince Alfreds pass. Again there were plenty of stops during the afternoon, with the final one at Sedgefield, before returning back to Plettenburg for a well earned beer.
I would recommend this to anybody and will go again when I am back in the area.
Good luck to Tim and Steve with their venture, hope it all works out well.
