The Migovec System ( Slovene: Sistem Migovec) is a 43,009-metre-long (141,000 ft) and 972-metre-deep (3,190 ft) [1] Alpine cave system within Mount Tolmin Migovec (Tolminski Migovec) in the Municipality of Tolmin in northwestern Slovenia. [2] The mountain and the cave system are part of Triglav National Park. The combined system is the longest known cave in the country, followed by the Postojna Cave System (24,340 m or 79,900 ft).

The entrances include: [5]
The majority of exploration has been carried out by the Caving Section of the Tolmin Mountaineering Club (Jamarska Sekcija Planinskega društva Tolmin), joined since 1994 by Imperial College Caving Club. [5]
Chough Cave (M2), Torn T-Shirt (M18), and M16 were connected together in 1996 [7] to form the initial Migovec System, which was then explored to an eventual depth of −970 m (−3,180 ft). [8] In 2008, exploration of Fairy Cave led to an almost immediate connection with Gardeners' World, and on 13 August 2012 Gardeners' World was connected to the Migovec System at a depth of −650 m (−2,130 ft).
Primadona and Monatip, two entrances located on the Western cliff of the Migovec plateau form a cave that was first explored in 1999. The cave was explored to a length of 2.7km before, in late 2015, being connected into the rest of System Migovec at a depth of −180 m (−590 ft).
