We visited this natural beauty spot out of season. The cavern only recedes every 20 minutes during certain months of the year. June is sadly not one of those months. The intermittent flow rate starts in July and as such I can't comment on the inside of the cavern. The water and spring is crystal clear and perfectly safe to drink. There is a path leading into the cavern that allows you to see inside and get to the waters edge. The water is extremely cold with a temperature of less than 12°C on a 28°C day. There is a car park right next to the cavern and opposite the cafe and adventure park. There is no fees involved in visiting the site. The area is amazingly clean and has bins around the vicinity. There isn't a single piece of trash in the whole area of the cavern or in the stream. Be extremely careful near the rock face in the car park and by the cavern as there is falling rocks which are as large as bowling balls. This is my only complaint. The rocks can damage your vehicle or cause serious injury and the car park is built right under this. Your only warning is the slabs of rock lying around the place.

There is an old man that comes with his bike and waits until unsuspecting tourists get trapped in the cave when the water suddenly rises. There are signs explaining this gimmick outside but we could not bother. 10/10 would be that tourist again.

Wir haben in Fontestorbes übernachtet und sind an dieser Quelle vorbeigekommen. Es ist ein schöner Ort zum verweilen. Das besondere, die Höhle wird in einem stündlichen Zyklus mit Wasser gefüllt und kann dann begangen werden, ist nur im Sommer der Fall. Wir haben die Schuhe ausgezogen und sind durch das Wasser gelaufen. Die Strömung ist recht stark, die Steine sehr rutschig und die Eisenstangen sehr alt und verrostet. Wir sind daher nicht bis zum Ende gelaufen. Einige Routen zum wandern und ein Hochseilgarten sind auf der anderen Straßenseite. Auf dem Parkplatz können ca. 10 Autos stehen.

Interesting visit in summer when the water stops for a while

Interesting quick stop with explanations in english of a cyphon effect

Intermittierende Quelle mit einem Durchsatz zwischen 1200 und 15000 Litern per Sekunde. Das Naturphänomen ist sehenswert.

Food here is always delicious and the spot is glorious.

Not too many visitors. Clear cool water. Some explanation available on his the water appears. Interesting enough.

An extraordinary phenomenon. Unless there is a drought and if there is a massive amount of rain, this spring, which comes out of a cave beside the road, starts as a trickle and rises to a torrent then subsides to a trickle again over 40 minutes. There are various theoretical explanations given on signs there but not actual evidence as to how/why this happens.

A beautiful little cave that you can walk across stones to access. In July, the water was quite shallow and very clear.

Lovely find, walked up from Belesta, two young children enjoyed the walk. Adventure playground was closed but looked interesting and has a cafe when open. The fountain is a lovely little cave with water, stepping stones (thirty ish) rake you into the cave and then come back out the same way. Wife took a dip in the water

A modest but respectable landmark, ideal for a 5-10 minute break from your travel

Nice but nothing special to see. You see water coming out a cave this all. But on the other side of the road is a nice place te eat and they all so have a climbing rooftop forest.

Very interesting piece of nature. It is worth waiting the time until the cave inner pool fills up, it is really stunning to see the water rise in front of your eyes

Not a very big attraction, but it is a cool stop. If you have time to wait for the water level to drop, and then rise again it is a cool phenomenon.

Very interesting

Very interesting natural phenomena worth a stop and Belesta is a beautiful little town for a photo stop.

Cool to see a natural event that slows the flow of the waterfall. When it gets low enough there are steps that allow you to cross the water into the cavern (although you can't go very far in). Go in the evening when there's less people.

Lovely spot for a picnic or whatever. Not enough water this week for the Syphon.

A wonder of nature. In this fountain, the amount of water that flows changes in 60 minutes in midsummer - like on-off. The origin is a geological phenomenon
