I recommend visiting Switzerland. I went a few years ago and I would certainly go again.

Some ideas:

- Visit Geneva and take a tour of CERN. It is home to the first web server.

- Bern has a lot of great things as well, from the Einstein Museum to being the home of the first cafe, Energy Kitchen, to have a Bitcoin Lightning Network self service kiosk.

- Kunstmuseum Basel has a lot of great modern art.

- And ofcourse, lots of skiing/snowboarding, snowshoeing and sledding.

There were bitcoin ATMs everywhere and were very simple, quick and easy to use. And travelling by train everywhere was great. And the views!
