Kitzbuhel or short and popular Kitz is very famous ski resort but you dont have to ski to experence the Alps.
We visited Kitzbuhel last week and it has been a great trip. We stayed in Q hotel Maria Theresa, hotel was Ok but nothing spectacular. Unfortunately if you want to stay anywhere close to center hotels are extremely expensive.
Driving to Kitzbuhel is as spectcular as it can be. Alpine peaks valleys waterfalls, we loved it. One great thing we did while driving there is visit to Osttirodler in Lienz.
This is an alpine coaster, it is 3,7 km long and great fun ( definitely recommend).
Main reason for our trip to Kitzbuhel was hiking. I definitely recommend, we went up to Hamenkamm and spent whole day hiking on the mountain. the view is great. There are few nice restaurants and a fun park for kids.
If you want to have a dinner in kitzbuhel center my recommendation is Huberbrau restaurant in the center ( very cheap but great food), another more expensive option is Zur Thene hotel restaurant.
