Prahova saline grandeur stuns everyone who visits.
Otopeni Airport can be reached by car in about 60-80 minutes. Unfortunately, during the summer, the large number of visitors, the waiting time for the descent into the mine can be up to 2 hours. Therefore, everything must be planned ahead to make the most of your valuable time.
Near the mine is Mount Green (tuff, a rock formed by the accumulation and consolidation of ash from volcanic eruptions) and you can take a dip in the saltwater lake. I believe that for a lightning trip to Romania a few days, these places can be seen in one dayg, especially if you combine sightseeing with a visit to Prahova Valley mine.
