If you like musicals and you are in Thun in July/August you should visit the Thunerseespiele.
The stage is mounted in the water and therefor the ambience of the musical is unique with all the mountains in the background.
Every year there is a different musical however normally in German language.
Dress Code: Take warm clothe (multiple layers) as the lake breeze can be fresh. They wil hand out rain coats (plastic) if the weather is not good.
In Grindelwald you can go to several pubs! One of the best is the espresso-bar. This is a nice small pub. But......., very special is the 'huttefeste'. In the bushes is a small dark wooden open house. This is a nice place to have a party.
