The castle can be visited 3 times a week: Friday to Sunday between 11:00 to 16:00 o'clock. There is a multilingual tour for visitors every hour.

The first major constructions were carried out in the 17th century by István Kálnoky III (judge of the Court of Appeal), who in 1648 noted in his diary the start of the building process on the "Miklósvári stone house". A rectangular, two-storey castle was built then in Late-Renaissance style. Dénes Kálnoky I (1814-1888) was the last proprietor from the Kálnoky family. As he died without descendants his sister’s son Ferenc Seethal inherited the castle. The current style of the castle and the form of the main façade are related to his building activities. At the beginning of the 20th century the castle was rebuilt in a Classicist style but the Late- Renaissance character of it was still visible. In 1939 after the death of Ferenc Seethal the castle was sold to Eugen Savu (Minister of Finance during the Goga government) but he lost it during the nationalization period. At the end of the 1990’s the descendants regained the building, which under the Kálnoky family’s care was renovated. The local government of Baraolt signed a contract for 49 years with count Kálnoky, because he intended to use the mansion in the field of tourism.

The easiest to reach the castle is by car, via the 103E road from Sfântu Gheorghe and then the 131 country road leading to Baraolt. The castle lies at a distance of 23 km from Sfântu Gheorghe. From Brașov, visitors should follow the E60 road, until the locality of Aluniș, and then turn on the 103E country road that leads to Baraolt.

The basement of the castle hosts a winery-café. Count Kálnoky's guest houses are located near the castle and offer accommodation for approximately 20 guests, ensuring meals and organizing various excursions for them.
