Indeed, this resort seems to be stuck in time, yes, you can get from Bucharest to Băile Herculane in two ways, the first way is by car, I think it's about 390-400 kilometers (you can do that in about 4-5 hours) and the second way is by train, which from what I know takes a little over 8 hours.
The location is quite far from the Romanian capital and it takes quite a while to get there.
I hope I was able to help you, if I can help you with anything else, write to me.
Thanks, car is not really and option I guess, and the train takes quite a while. Still, I have the post bookmarked ;)
Unless you opt to rent a car (that is, if you have a driver's license), and yes, the train takes forever.
If I can help you with anything else, I'm here.
Thanks, I appreciate :)
