Istria, due to its soil types (karst and limestone) has a lot of underground caves. Several of them can be visited without a lot of speleological knowledge and equipment while for a large number of them, however, You need more experience and specialized equipment. Underground chambers, lakes, streams, pits, gorges, crevices and petrifactions will surely inspire each visitor with enthusiasm. Apart from natural beauties, Istrian caves and pits are a treasury of animal and plant world (fish, frogs, dormice, crabs, bats), the most interesting among them being Proteus anguinus, endemic species that inhabits only these Karst areas. MoreBack The world-famous abyss Pazinska jama has gained popularity thanks to Jules Verne who described it in his novel 'Mathias Sandorf'. Some 1500 caves have been registered until today, and each year there are about 10 more newly discovered ones. Visit the underworld the Baredine Cave. This cave is a treasure chest of stalagmites and stalactites, underworld sculptures created through time by the patient work of water Ćićarija in the north of Istria is a separate Karst entity with the deepest Istrian pit called Rašpor, 361 m deep. Near the town of Roč are abysses Krkuž and Gragorinčići. The longest cave in flysch is Piskovica in central Istria, 1.036 m long. Nearby is also Marfanska pit, 273 m deep and with its 2,045 m of explored underground passages is the longest cave in Istria. Batluška pit has the largest chamber, 200 m long and 150 m wide, measuring a height of 60 m. The north-western areas, where flysch layers come in contact with limestone, are specific for the great number of abysses. An exceptionally picturesque one is that near Šterna, 231 m deep, and it is specially beautiful in the rainy period when a wonderful waterfall forms, creating a lovely small lake at the bottom of the valley before disappearing underground. In the vicinity is an old abandoned mill. Specially interesting is the Karst zone of western Istria covered with red soil, so that very often stalactites, stalagmites and crystals are vividly red. In addition to pits, caves are very interesting speleological sites as well. Because of its accessibility, the presence of people and animals in them goes back into the distant past so many of them are today still interesting archaeological and paleontological sites: Šandalja, Vergotinova, Romualdo's Cave, Trogrla, Mramornica cave, Feštinsko Kraljevstvo cave… are only some of them.

Istra je zbog vrste tla (krš i kras) prepuna podzemnih špilja i jama. Neke od njih moguće je obići bez većeg speleološkog znanja i opreme, dok je za velik broj njih ipak potrebno više iskustva i specijalizirane opreme. Podzemne dvorane, jezera, potoci, grotla, vrtložni lonci, pukotine i okamine oduševit će svakog posjetitelja. U istarskim spiljama i jamama osim prirodnih ljepota nalazi se i raznovrsni životinjski i biljni svjet (ribe, žabe, puhovi, račići, šišmiši), a najzanimljivija je čovječja ribica, endemska vrsta koja živi samo u ovim kraškim područjima. OpširnijeNatrag Svjetski poznata istarska jama postala je Pazinska jama koju je proslavio Jules Verne opisivši je u romanu 'Mathias Sandorf'. Dosad je poznato oko 1.500 jama, a svake godine otkriva se desetak novih. Posjetite podzemni svijet Jame Baredine. Ova je spilja riznica stalagmita i stalaktita, podzemnih skulptura realiziranih strpljivim radom vode vjekovima. Ćićarija na sjeveru Istre je zasebna kraška cjelina i tu se nalazi najdublja istarska jama, ponor Rašpor, dubok 361 metar. Kod gradića Roča su ponori Krkuž i Gragorinčići. Najduža spilja u flišu je Piskovica u središnjem dijelu poluotoka, duga 1.036 metara. U blizini se nalazi i Marfanska jama duboka 273 metra koja je sa svojih 2.045 metara istraženih kanala ujedno i najduža u Istri. Najveća dvorana krasi Batlušku jamu, dužine i širine 200, odnosno 150 metara i visine 60 metara. Sjeverozapadni krajevi posebni su po nizu ponora u pojasu kontakta flišnih naslaga i vapnenca. Vrlo je slikovit ponor kod Šterne dubok 231 metar, a posebno je lijep u kišnom razdoblju kad se stvara predivan slap koji u dnu vrtače, prije poniranja stvara slikovito jezerce. U blizini je i stari napušteni mlin. Posebno je zanimljiv kraški pojas zapadne Istre prekriven crvenicom pa su ovdje sige i kristali u podzemlju često izrazito crveni. Osim jama i spilje su vrlo interesantni speleološki lokaliteti. Zbog svoje pristupačnosti boravak čovjeka i životinja u njima seže u daleku prošlost tako da su mnoge od njih danas zanimljiva arheološka i paleontološka nalazišta: Šandalja, Vergotinova, Romualdova pećina, Trogrla, spilja Mramornica, Feštinsko Kraljevstvo… samo su neke od njih.
