Thuringia (Thüringen) is a state of Germany.
Thuringia is one of the least known German provinces amongst foreign travelers but enjoys a good reputation with local vacationers.
A predominantly mountainous and forested region, Thuringia is also known for a quartet of beautiful ancient cities and the Wartburg Castle - regarded by Germans as the most important castle in the country.
Thuringia's boundaries are Bavaria (specifically Franconia) to the south, Hesse to the west, Lower Saxony to the northwest, Saxony-Anhalt to the north, and Saxony to the east.
The most common language in Thuringia is German with its slight regional accent.
Public transport is for the most part good fast and reliable. If you plan to do a day trip the "Thüringen-Ticket" might just be what you are looking for. It costs 22€ for one person plus 4 € for each additional up to five and covers all regional trains in Thuringia, Saxony-Anhalt and Saxony plus public transport in Erfurt, Gera, Weimar, Jena, also Halle and Leipzig (not Dresden though). Validity is from 9 am on working days (all day on weekends) until 3 am the following morning.
The state of Thuringia is generally safe. However, never leave your belongings such as wallets, luggage, and any other bags off you on the streets, you might get them stolen. And the polizei at the police station don't speak English well so they won't be too helpful even if you face the trouble.
