There is no guided tour, the tickets are valid for the whole day. Visitors can enter the mine by coach, the center is more than 3 km underground drive from the entrance and 136 m below the entrance.

Above ground is a swimming pool with salt water or brine from the mine. There are showers, the doctor's office, a terrace and a shop.

The Trotus mine or Troilus Salt Mine is a working mine, currently the salt is mined on the levels X and XI. The tourism activity is concentrated on the ninth level. The salt is mined in the classical mining technique. Holes are drilled into the salt and filled with explosives. After the firing the broken salt is transported away and the cycle starts over again.

One of the highlights is definitely the underground muzeului sării (salt museum) which has exhibitions on the formation of the salt deposit, the development of salt mining and processing, and the halotherapy. There is an exhibition on local history and the development of the salt mining.

Another highlight is Biserica subterană Sfânta Varvara (Underground Church Saint Barbara). It is rather young, it was built in 1992 on the initiative of the employees of the mine. Nevertheless, it is the first underground Orthodox church in Europe. And as it is inside a mine it was dedicated to Saint Barbara, the patron saint of the miners. The iconostasis in front of the altar consists of 24 icons from 1924. On the left side is the icon of Saint Barbara and on the right side the icon of Sf. Cuv. Parascheva, the protector of Moldova. All icons and other items of the chapel were handcrafted by miners. Every year on the 04-DEC, the day of Saint Barbara, a service of honor and remembrance is celebrated by the employees of the unit, their families, the founders and inhabitants of the area. Since 2016 Father Elisa Roncea was appointed priest of the church. He established the church ordinances as in any other parish church, tourists and believers can attend to the Holy Mass every Saturday, Sunday, and Holiday. The Sacrament of the Holy Anointing and the service of Aghiezma are celebrated on Wednesday or Friday.
