Early morning and sunset tractor-rides through vineyards are the best. I've just discovered how difficult it is to find somewhere (near Cape Town) to go on a tractor-ride. But nevertheless I've managed to find a wine estate in Wellington that does just this. Diemersfontein Wine & Country Estate offers tractor-rides for 6 people at 35ZAR per person - including a glass of wine! At that price the cynic in me says that it must be a glass for everyone to share, but Kerry-Anne's convinced that it's a glass per person.
Check out Diemersfontein's website and consider doing some of the other activities, like perhaps a picnic, horse ride or short hike.
