The service area Kölliken-Nord (AG) is located on the A1 Zurich-Berne.
At the car park you will find a small cosy place with tables and benches under trees.
If you want to move around a bit with your 4-legged friend, you can go through the small gate (open all the way through), turn right at the bottom of the path and follow the cycle path.
Here also runs a stream where the dog can cool down optimally.
Unfortunately dogs are not allowed in the rest area / shop.
