Dublin caving Portrane caves I was visiting Dublin for a conference, but managed to sneak out for an early morning exploration on one of the days. I had already skied in Dublin eleven years ago. But I had not been to a cave in Ireland! Are there any around? I found an article from the award-winning local cave photographer and author Robert Mulraney which said, "The first thing that can be said of the caves of Dublin is that, there are no caves in Dublin". However, it turns out there are some, and Robert goes through these in his article. The caves are not big.. but very interesting. And actually, they *are* big for someone coming from the land of thousands lakes and mini caves :-) Full story
Caver's X-Mas Party with Dresses I hosted the fall meeting and Christmas party for the caver's association in Kauniainen. The theme was vintage clothing... I was maybe more vintage, clothing and otherwise than the others... Full story

Latokaski mini-caves I was walking back from my car repair shop, having returned by loaner car... and they are working on my Volvo. Let's see if they can fix it. It's been there six months soon, and even under work for more than a month. But on the way back I run into small holes in a rock outcrop in Latokaski. Too small maybe to call a proper cave. But certain space where you can go under a rock. Full story

The Pitsusköngäs waterfall cave Last month Duncan, Jarmo, Kimmo and me did a cave exploration trip to the Käsivarsi wilderness area. Peeking into every hole we could see, combing through areas of limestone, etc. The most memorable for me was the Pitsusköngäs (Bihčosgorži) waterfalls, highest in Finland at 17m free fall. And there was some space underneath, maybe 10x6-8x8m. Can we classify that as a cave? Full story

The search for Toskaljärvi area caves peek into every hole In August 2024 we explored the surroundings of the Toskaljärvi lake and Doskalharj mountain. Our mission was to find caves, perhaps a desperate mission in this landscape that is mostly marked by small, broken up rock... but there are areas of limestone, larger boulder fields, canyons and cliffs all of which we wanted to check out. The mission turned then into a "walk everywhere and peek into every hole you can see". Of course, most of those holes were rather small in closer inspection. Full story

Beach cave tunnels at the Srebrna Beach The Srebrna Beach is a popular, rocky beach in the limestone layer of on the south side of the Vis island in Croatia. Beach caves are a very frequent occurrence on Croatia's coast, but for me - coming from a cave-poor country - they are always a wonder. There's a very nice straight, tunnel-like beach cave on the left side of the Srebrna beach. Full story

Worth squeezing in We stopped on a road for taking photos of the scenery. While taking the photo, I noticed that there was a small hole by the road. It looked tight and steep, uncertain if one could go in. At the bottom of the hole there seemed to be a couple of boulders. I returned a couple of days later equipped with better clothing for exploration. It turned out to be a 30m x 18m beautiful stalactite cave! Proof that it does indeed sometimes pay off to peek into every hole! Full story

Movie night geology and caves in the Vis island region Komiza is a small fishing village on the island of Vis, off the coast of Croatia. It is perhaps one of the most real feeling places that I've visited in the Croatian archipelago. The houses are old, stone-built, the streets are narrow and for walking only. The views are great. But they also have an open-air movie theater, and an information center for the UNESCO's Vis Archipelago Geopark. And I happened to hear about a movie they were premiering in the theater, about the origins of island, their caves, and geology. Including some newly published research that changes the current understanding of how the islands formed! Full story

The Secret Beach in Komiža I have been here before, but then the tide and my clothes were not suitable for exploring. Now they were! I also did not understand the naming the beaches I was at, but I do now. The cave I'm looking at is at the Dog Beach, literally the beach that the dogs (and people) can swim at. A bit further out from the Dog Beach there's the Kamenice Beach, also called the Camp Beach due to the nearby low-cost but forbidden accommodation option :-) Both beaches can be accessed easily with chairs, have a bar, etc. However, between them there's the Secret Beach. To get there you have to go through a cave and climb, wall across a part of the sea that is only passable easily during low tide (picture above), or straight out swim. Full story

Ape Cave Lava Tunnel Adventure by Mount St. Helens Ape Cave. Named after the scouts helping to explore the cave, back then called the "cave apes". One of my most amazing cave experiences. This cave is easily and safely accessible by anyone -- as long as you register yourself and your vehicle for the visit at the US Forestry Service. In the cave you can do just a small peek underground or walk 1 km to the nearest end of the cave on an easy path. Someone was even pushing strollers. And then you walk back the kilometer to exit. But you can also keep walking also to the other end of the cave, and then exit from the other exit. This is what I did, and that's a whopping 5.5 km walk underground. The cave is the third longest lava tube in North America. And with such amazing sights, e.g., the one in the picture above. Much recommended! Full story

Chilliwack River Caves Fail. I did find a cave, a small one, but I only later learned there would have been a much bigger cave higher up. And the other cave I was searching for ... I could not find. I guess the coordinates were wrong. Oh well, it was a nice outing by the riverside. Full story

Jorvi Crystal Tale There's no information about this in the Internet. But, at the Jorvi hospital in Espoo there's a display about "perhaps the largest mountain crystal deposit in Finland". The story goes that while the underground shelter for the hospital was being built, a worker drilled into an empty cave with an elf and crystal covered walls. The worked grabbed a piece of the crystals before the elf closed the hole. Full story

Bosnian Pyramid of the Sun I visited the Bosnian Pyramid of the Sun, as well as the Ravne tunnels few kilometers away. The pyramid is remarkably pyramid-looking green mountain and the tunnels are .. well, more about that later. Both are in the small town of Visoko, 35 kilometers outside Sarajevo. The claim is that the pyramid is a concrete-covered man-made structure built by an ancient civilization 29 000 years ago. And that the tunnels were also man-made network leading under the pyramids, and only later filled in. And that there are health benefits to all of this. Long story short: lots of pseudoscience, but of course a nice mountain to visit. And it is always pleasant to be wet, dark underground tunnels. Even if the the support beams are rotting... Full story

Bijambare Caves My first "proper" Bosnia and Herzegovina caves! The Bijambare caves. Wonderful karst caves, and in the largest one there are massive halls and massive tunnels. Well worth visiting if you're near Sarajevo! Full story

Through the grey stone In Finnish we have this expression, "läpi harmaan kiven". It translates literally as 'through the grey stone'. It represents sisu, another Finnish concept: going through no matter what. Even through rock. Here Harri-Pekka Pietikäinen demonstrates the concept. Full story
