Will be in Geneva during August for 6 days 5 nights. Thinking to spend 1st day in town and take train to visit Montreux and Chillon for a day. another day to Interlaken and 4th day to Zermatt. Last day to see more museum in Geneva. Does that sounds too busy? I would like to see the old town, lake and mountains. Since I have hotel booked in Geneva for whole week so have to plan day trip. Is there any suggestion? Thank !
