You now need to book up early if you want to do the 4 hour Krizna cave tour in Green Slovenia. We have had some guests disappointed when we phoned up for them just a few days before to see if there were any spaces and there weren't! Sometimes you can get a cancellation, but we now recommend that if you are staying here in the summer, particularly July or August, then get us to book your spaces at least a month before you arrive.

The biggest problem is that people might not have heard about this amazing cave until they reach Slovenia and then it might be too late! You won't have this problem now as you will have read this!

The Krizna cave is one of the rarest finest cave examples of an underground calcium river still forming. The location, the passion of the local guides and the underground paradise you will see are simply unmissabubble.

The cave is strictly protected and ONLY 1,000 people per year may do the 4 hour trip. Tours are for a maximum of 4 adults who go with one guide and once you get past the limit of the shorter one hour tour you have to walk exactly in the footsteps of the guide to protect the cave & river and help carry the rubber boat & paddles that you will use to explore this underground wonder of the world. You do not do this tour in flip flops and a T shirt, we wore 4 pairs of socks inside our wellington boots and for many this is about as close as you can get to being a real caver and you will have a genuine Slovenian adventure!

We were lucky enough to do the 4 hour tour and believe us, it is literally out of this world. You will see one of only 6 massive stone cave mushrooms in the world, a pirate ship, Slovenia's largest underground island and step into a wonderful underground cascade! Again just believe us that the 4 hours will absolutely fly by.

We often compare the 3 best known Slovenian caves to London, New York and Paris.. you wouldn't say, "Oh I'm not gonna see New York cos I already saw a big city in London" Nooooooooo, of course you would want to see them all as they are all big cities, but so different in character and feature.. Well, it's exactly the same for the big (by virtue of being the best known) three Slovenian caves. Skocjan is a completely different wonder to Postojna which is another completely different experience to Krizna.. Our strong advice is to see them all.

Booking a Tour at Krizna cave> for the website booking PLEASE CLICK HERE

There is a 1hr standard tour, a special 1.5hr tour, this amazing 4hr tour & the 6 hr extravagansa to Crystal mountain

The main tour for which you do not need to book for is the 1hr, available all year round and you can just turn up for that one. You get to walk down into the cave and see the river forming and also get an amazing rubber boat ride to the mouth of the second part of the cave where the 4 hour tour continues. But please do not make the mistake to think the hour tour will be in any way a compensation for the 4 hour. The one hour is fantastic and great for the family, but the 4 hour is so spectacular and unique you will never forget it.

A slightly longer 1.5 hr tour is also offered, where you get to go on the main boat and then do some exploring further along a side tunnel.. best to check directly with the website or phone if this is the tour for you.

You need to book ahead on the Krizna Cave website for the longer 4 hr tour. You will only be able to click on a day if it is available, so you will know immediatelly if you can do that tour.. Remember the 4 hour tour is for a maximum of 4 adults, or a family with older kids.

The much longer 6 hr tour to Crystal mountain also needs to be booked online and this is high on our own list of "secret places to visit" still to do!

If you think about a cave filled with water, then you might want to visit Slovenia in the summer, but this is when there is the least amount of rainfall, so there is a small chance that your tour cannot go ahead. In the same way if there is a really huge amount of rainfall, then it might not be safe to due to higher water levels. The cave staff are experts on this and it is very rare that a tour gets cancelled, but it does happen and then you are usually offered at least to do the 1.5hr tour, so at least you get a bit further down the cave.

So if you are very very excited about doing a 4hr or 6hr tour then you might want to think about visiting Slovenia outside the summer months, Slovenia is an amazing place to visit at all times of the year anyway, this is a key message that we want to get out there.

There are lots and lots of other Slovenian caves you have not even heard of.. in fact almost 15,000 have been discovered and with just a little bit of effort and help from us we can get you inside one of them with your own guide.. simply cavetastic! You can find out a bit more in our CAVES section.

Finally, one of Slovenia's most stunning castles, Sneznik (Snow Mountain) is just down the road from Krizna and is such a good combination for you to visit after the cave and warm up on the edge of the thickest and oldest forest in Europe. Pretty much all our guests who go to the cave also go to this castle and experience yet another day filled with a little bit of Slovenian magic and surprise.

And below our friend Gasper from the Krizna cave has allowed us to use some of his special photos from deep inside the cave for our gallery.. thanks Gasper!
