Hello fellow travelers,
Please excuse my ignorance in this post, I am fairly new to venturing out and want to get ideas from those with more experience.
I am planning a two week holiday with my parents (mid 50-60s) in summer of 2025 and we have always wanted to visit Switzerland for it's nature and beauty. We all love the sun and prefer to stay away from the cold. My father loves taking long walks, caves, gorges, and I prefer 2-4 mile hikes along with biking. My mother enjoys getting her feet wet in lakes/streams. We prefer to have a quiet time with lots of outdoor explorations. We were originally planning on visiting Lauterbrunnen but I'm having some hesitations due to it being a popular tourist spot, being 2 hours drive from Zurich and I've heard it receives less sunlight in the valley due to it's location.
I am now thinking on going somewhere in eastern Switzerland so that we can also make drives to the western part of Austria, maybe south to Tirol and then up through Lichtenstein and Lake Constance. That way we can experience a little bit of Switzerland, Austria, Tirol in Austria if possible, Lichtenstein and Germany. We might change the duration of our trip once we have more solid plans of our route and which places to visit.
So my question is, what are some good places to visit in east part of Switzerland that will fulfill our outdoor hobbies? I'm also open to recommendations for around western Austria, through Lichtenstein, lake Konstance as well? We will be renting a car so can visit areas within 2-3 hours of each other. We prefer to have a quiet time and refresh our minds for the time we spend in Switzerland. Shopping (except groceries) is not important but if castles, caves, waterfalls, historic sites are nearby then we would visit.
Anything else that you think I should know, I greatly welcome the suggestions and insight.
EDIT: To add, I don't like driving much, since it's holiday I wan to spend the maximum time enjoying nature and castles etc. That is also one of my reasons for choosing a place where I can drive 2 hours at a time to explore the next spot. I know trains are good in Europe, but since it will be our first time there, I want to have some control over where we go, and at what times.
