Mathishof has the most amazing, Enter the labyrinth and wind your way through the maize to find 4 or 5 kids play areas that include slides, swings, trampolines and other fun things to play on. Take the zip line through the maze to cut a corner or wander around until you find the exit. The labyrinth is not so complex that you can get lost but you do need a good 30 mins to 1 hour to enjoy it fully. Be warned, I imagine many children could spend a lot longer than that though!
The Fünfschilling is a restaurant on a vineyard that is tucked away in Fischingen and small village near Binzen in Germany that is around 25 mins drive from Basel. Fünfschilling is a great place to take the entire family to have an inexpensive family meal, to buy reasonably priced wine, spirits and visit their farm shop that is packed full of seasonal fruit and vegetables and other tasty treats. They also have a wonderful playground for kids and some really yummy cakes.
