This is a list of the longest caves in the Dinaric Alps. This region is known for its deep caves more than its long caves, in part because of the slow progress of cave exploration and in part because the recency and severity of the uplift is less favourable for the developmet of caves with extensive accessible passages. The cumulative explored passage length of all Dinaric caves is comparable to Mammoth Cave, presently the record-holder for most explored passageway.
Slovenia, Croatia, and Serbia each had national lists of longest caves in Yugoslav times, during which they were often compared. A continuously updated list is available for Slovenia. [1] For Croatia, there is a periodically updated list of caves longer than 1 km and deeper than 250 m. [2] The Katastar speleoloških objekata Republike Hrvatske remains closed to the public, but excerpts are available at Bioportal. [3] The first list for Serbia was published in 1981, [4] followed by an online list no longer updated after 2011. [5] A list of all caves in Serbia longer than 100 m was published in 2022. [6]
This list is incomplete, missing caves shorter than 1000 m (Croatia, Slovenia), and most long caves in the remaining republics, although the coverage for Serbia could be improved from published lists. [6]
