Vulcanii Noroiosi

I’ve been there two times.
First time it was very difficult to find them… There is an sign on the road that says “Vulcanii Noroiosi” but once you get there, there’s nothing telling you to stop and climb the hill next to you. We just drove back and forth a few times until we stopped to ask the people down at the oil pumps for directions.
The second time I went (with another group), we got there with no problems… And there was no hill climbing. Road lead right in there… Very strange.
Checking out what happened, I later found out that there are two “Vulcanii Noroiosi”, the large ones and the small ones. That must be what happened: each time I went to a different place.
