Lake Saint Anne (alt. 946m) is a crater lake located in a volcanic crater of the Eastern Carpathians, unique in Central/Eastern Europe. Sometimes the weather here is changing rapidly from sun to clouds and winds and so on, however, the place is strangely peaceful, makes me to think of X-Files or Twin Peaks atmosphere.
Nearby there is a small village called Balvanyos, more or less in the middle of nowhere, few hostels and a restaurant and that's it, well, a really good place to eat, and extremely cheap, people from other counties are coming here just for that; you can hear about this place in Germany or Hungary. It is highly recommended to have a break before driving back on the winding road.
