Slovenia is a country full of caves, with upwards of 8,000 on record and more being reported each year. Adventurous travelers will want to take a day or more away from the beaches, skiing, and mountain hiking to explore the famous Slovenia caves. If you can imagine yourself on a small boat paddling over emerald-green water in a subterranean lake, then Slovenia cave tours might be a great activity for you. Tours of the caves in Slovenia are offered for a range of fitness levels, so whether you’re looking for a leisurely stroll or the chance to climb over piles of rocks, there is a tour for you.
Krizna Jama is one of the best-known caves in Slovenia. Translated as Cave of the Cross this cave extends more than 100 feet deep and is more than five miles long. Krizna Jama is especially known for its 22 subterranean lakes, remarkable for their emerald color. Descending into the caves by foot and continuing the tour on small boats, visitors will be introduced to an incredible amount of biodiversity by cave standards. With more than 40 species of organisms, this is the fourth most diverse cave system in the world with regards to biodiversity. There are two types of tours available: a one-hour tour that is done on a first come, first serve basis, or a three- to four-hour tour that must be booked in advance.
There are two paths to take in Krizna Jama: one branches to the north and another to the northeast. The branch to the north is considerably more difficult to traverse, and many visitors find themselves on the northeast branch instead. After the use of small boats on this itinerary, visitors will find themselves in the largest room of the Slovenia caves, called Crystal Mountain. Here, explorers can leave the boat behind to climb some of the collapsed rocks to a height considerably above the stream. First documented in the 1830s, Krizna Jama is now known internationally for its beauty, intrigue, and green waters.
Caves in Slovenia maintain a constant temperature of approximately 50 degrees, so when planning your visit, be sure to bring warm clothes. The stunning display of stalactites and stalagmites continues in other Slovenia caves as well. Planinska Jama is another popular cave attraction for visitors. One of the longest caves in Slovenia, Planinska Jama is a huge tunnel that is the subterranean bed of the Unica River. Roughly 1,600 feet from the striking entrance, the tunnel divides into two. An iron gate prevents visitors from going down one tunnel on their own, but special tours with experts can be arranged to ensure your safety. Planinska Jama is especially popular with photographers, as the way sunlight enters the tunnel is particularly beautiful.
Another striking cave system in Slovenia is the Skocjan Caves. On UNESCO’s World Heritage list, the Skocjan Caves are both beautiful and mysterious. The longest cave system in the country is the Postojna Caves. One of the top tourist attractions in the country, the caves were created by the Pivka River. Tours at all of these caves will illuminate precisely what visitors are seeing, and tour guides will reveal how the caves were created. In these places that have been explored for hundreds of years, you too can enter the dark depths beneath Slovenia for your own adventure tour.
