Did you know you can buy milk fresh from a farm within a short walk (15-20 minutes) from Nyon? The milk is for sale via a self service machine (see photo below).
You can either take your own container, or buy one at the farm. Take cash for the vending machine.
One litre of milk costs CHF 1.50 Three litres cost CHF 3.00
The farm (the Domaine de Bois-Bougy) is open 7/7 and sells other fresh produce (cheese, eggs yoghurt, home-made jams) out of a Portakabin next to the farm.
There are various walking routes to get to the farm. One of them takes you through the Sentier du Boiron lovely woods alongside the Boiron river. More details here
