In the morning we visit Chateau Chillon, the medieval castle on the lake of Geneva. Afterwards we pass through the Valais Valley and depending on the weather we either visit an underground lake or drive to Zermatt from where we have a marvellous view on the iconic emblem of the Swiss alps - the Matterhorn - which is said to be the most beautiful mountain in the world. While driving over a mountain pass we stop to have a look at the impressive Rhone glacier and even walk around inside the glacier.
