Members of the Croatian Mensa Association receive 50% discount on travel in the 1st and 2nd class of regular trains in domestic traffic. The discount is available until 13 February 2026.

The approved discount does not apply to special trains and the use of beds in sleeping carriages or berths in berth carriages.

The discount is realized by presenting the Mensa membership card or by presenting the Mensa membership certificate at the HŽPP ticket office or on the train. During ticket inspections on the train, Mensa members should show the train crew a valid membership card or a certificate of Mensa membership.
