There are alternative routes to get to the snow fields. Our advice is to avoid going through the town of Ceres. It is quicker (maybe not as pretty) to take the N1 through the tunnel, Worcester, De Doorns, and the Hex Rivier Pass. A few kilometers past the summit of the Hex Rivier pass, there is tar road to the left (West) marked as the R46. Take this road for approximately 30 km till you see a gravel road heading off towards a a farm on your left (South). This road will take you up a small pass (Uitkomst Pass) and deliver you just 3kms later at the entrance road to the Erfdeel farm (Matroosberg). (Read the blue hyperlinks in the text for more information on the alternative passes and routes).
Once you have finished playing in the snow, you have several options getting abck home without having to go through the traffic bottleneck in Ceres.
From Matroosberg, head South past the Klondyke Cherry farms on the Theronsberg Pass. Where this tar road forms a T-Junction with the R46, you can turn right and had up the Swaarmoed Pass and follow the road all the way back to the N1 and home.
Another alternative is to take the road to the left halfway along the Swaarmoed pass which wil take you across the Koue Bokkeveld to the tar road from the Gydo pass to Citrusdal. It's a fairly long (but beautifully scenic) drive which will take you past the Hamlet of op Die Berg, down the Middelberg Pass to Citrusdal. There you can turn left onto the N7 and drive the Piekenierskloof Pass. This routing should have much lighter traffic.
Drive safely.
