We are considering trip to Carinthia for a week this August, 9 people ages 7 to 75. We are looking for a place that is a) on a warm lake; b) close to scenic hikes/mountains c) close to at least 1 castle d) does not require complicated driving on a lot of mountain roads; e) not in a city. Optimal lodging would be an inexpensive rental or camping. My question is: which areas in Carinthia should we be looking at? Websites are very vague! Please help!
