I did this as a solo trip and loved it. We started off at the Chaplin House which was entertaining and informative. Followed by a short picnic with our tour guide in Vevey. After (if your purchase the boat ticket) we went on the boat to the castle. Lastly we ended the day off with some time in Montreux. Your guide will take you everywhere, explain everything thoroughly and make sure you have meeting points/times. My guide was fantastic! It’s a long day with lots of walking but I didn’t even notice because of the fun I was having! Despite it being overcast/rainy the views were still breathtaking and we made the most of the day. Highly recommend this tour.
