Venice again, no skiing, just heat
Many years ago, I tried to find some skiing inVenice. No luck, could not score any snow from local skating rinks, so was unable to plaster the Calatrava Bridge with snow... sad... or maybe good. This year we went back there.

Predjama Castle
I had only heard about the Postojna Cave before coming to Slovenia. But it turns out that there are many caves (of course) as well as many very interesting or famous cave sites. Right next to the Postojna cave, a 10 minute car ride away for instance is the Predjama Castle, which is world's largest castle built in a cave.

Walls of Piran
Piran is a medieval town on the coast of Slovenia. A wonderful town, clearly retaining its historic parts. The protective walls of the city date back to the 7th century, and can be toured for a nominal fee. Much recommended.

Northern Croatia swim
On our tour of Slovenia's Piran, we also peeked on the Croatian side, and had a swim in the Polynesia Beach in the town of Umag. Little did we know that the ruins we started our swim from were actually the ruins of the Sipar Castle from A.D. 1000 or thereabouts. Some have even called this place the Atlantis of Sipar. Interesting!

One kilometer walkway tunnel
This tunnel appeared on my walk while visiting Rotterdam. I was walking from my hotel to the conference venues, as a like to do to keep my step counts up :-) And as one expects, there are some waterways to cross in the Netherlands cities :-) I thought there'd be a bridge though. But no, it was a tunnel. It was only in the tunnel and later in Wikipedia that Maastunnel is actually 1070 meters long that crosses the Niewwe Maas.

Trust me, it is NOT a watertower
It does look very weird. For some reason I thought it was a water tower. It is in the town of Oberreid in the Black Forest area in Southern Germany, near Freiburg. But ... it is in fact a defense against against nuclear weapons and natural disasters...

Enoshima Caves
Only in Japan: They have a "candle lending service" at cave. And it is not like it is a dark, lightless place even without the candles - the Enoshima cave has lighting, but obviously the candles are a remarkable addition to the experience. On the other hand, since the candles are actual candles with actual fire, there is now a need to have a fire alarm system, if somebody accidentally sets the cave on fire...

New ZIF-25 bunker in Siuntio!
We had heard a rumor of a potentially previously unknown bunker in Siuntio. Let's call it the Hoivakodin Bunkkeri (Retirement Home Bunker). It turned out to be accessible -- if you don't mind passing through pieces of concrete hanging by rusting, twisted rebar. And it was a massive one! Another ZIF-25 model bunker, i.e., a two-floor bunker with several entrance tunnels and a side mountain gun port.

Slava Ukraini!
I saw something today that I didn't realize actually existed in our neighborhood. It takes maybe half an hour for me to get from where I live to Siuntio, and there's a nice castle, the Sjundby Castle (or Manor). It was built starting from 1417, by the rapids on the Sjundbyån river. It is not open to the public so maybe that explains why I haven't heard about it.

Tower and Cave in Alíartos
A random discovery while driving through Greece's small mountain towns. A massive hole by the road, with a tower on of the rock hill. This was so sudden that I didn't even think of registering the location or stopping. And I was in a rush to get to the ski area anyway.

Wiesliczka Salt Mines
Wiesliczka is a suburb of Krakow. Under it is a massive salt mine, extending to a depth of approximately over 300 meters, with the total length of labyrinth passages spanning over 287 kilometers. The use of the site dates back to the 13th century, where the locals would harvest salt from brine (salt concentrate) wells dug on the wetlands. Later in the same century the wells started to be extended as deeper mine shafts and tunnels. Wiesliczka is not just a mine, it is a massive underground world and site of art and history. It is also a well-deserved UNESCO World Heritage Site.

Refresher course in communism and nuclear bunkers
I've been here before, but a refresher course is always good, plus I have the next generation with me, useful course for him as well. The Prague's communism and nuclear bunker tour is a good reminder of what oppressive things went on during the eastern block years in Czechosloakia and elsewhere. Fortunately, those times are past us. But in 2022, you can still feel the nuclear-bomb threats being made ... you guessed it, from the east.

Castles, castles... Czech edition
I had an opportunity to visit castles in Czech Republic this summer. The first one we went to was Hrad Trosky, the ruins of an amazing two-tower steep clifftop castle. What a magnificent, for defense business -only castle! The second castle, Hrad Kost was a more full-service one, and was used as an administrative base. With a torture chamber, of course. (Is there any other kind of administration???)

South Czechia castles Rabí and Kašperk
Our trip to Czechia concluded with a road trip to the Kašperk and Rabí castles. Both are medieval castles, partially in ruins and partially restored. Kašperk's two-towers-on-a-steep-hill design reminded us very much of the Trosky castle that we had seen a few days earlier.

Vrnik Quarries
Otok Vrnik is a small island close to Korcula (town) and the Korcula island. Otok Vrnik's history revolves around quarries ... the whole island is a quarry. Since the activity has stopped hundreds of years ago, there's little that you can see today, but there are some places where big walls of rock are still visible.

Anna Mine
60 kilometers southwest of Prague is a historic mining area of Příbram. There's mining museum at Mine Ševčinský. There's also two mines that you can actually visit, the Hornické muzeum Příbram – Vojtěšský důl (Vojtěšský mine) and the Hornické muzeum Příbram – Anenský důl (Anna Mine). The latter involves a small train journey in mine carts...

Mali Kozjak hike
Mali Kozjak is a mountain ridge in Split, Croatia. Near the airport, in fact. I had seen this on a previous trip, and it looked interesting... was there a hike? After perusing through the Wikilocs and Starves of the world, and some (maybe not enough) local advice, it seemed like there's a nice walk up via the Planinarski Dom Putalj mountain hut. I chose to hike up a bit further north so that I could descend to the hut. But boy did that generate some headache!

Sutro Baths Tunnels
The Sutro Baths were luxurious swimming pools on the San Francisco seafront, in an almost all glass building, built in the 1890s. Complete with salt and freshwater pools, slides, and 30 swinging rings, and a springboard. It was served by two rail lines, one of these being the Sutro Railroad, another creation of Adolph Sutro, a famous engineer and industrialist and mayor of San Francisco! In the 1900s the facility fell into disrepair and it burned down in 1966. Today only ruins remain, including the pool basins, a settling pool, and tunnels.

Zagrebenje bunker maze
Croatian islands have had a military past. During World War II when Tito held his headquarters on the island of Vis. After the war, Vis was turned into a defense bastion, and only opened for foreigners as late as in 1989. Today we toured a maze of tunnels on the Zagrebenje mountains on the southeast corner of the island, connecting a number gun positions.

Apartment Carved out of Stone
Coming back from the skiing on the Mount Olympus and Troodos Mountains in Cyprus, I was driving by an area that had reported some kind of underground passage. I stopped to find out what it was about. From the map it looked like it was near a road, but it turned out to be only near some kind of agricultural path, and a kilometer or two from the drivable public roads. Well, why not walk to the darkness on the first night in a country you've never been to...

Looking for caves in Lohja's Linnanmäki in Karstu
The evening's excursion was to Lohja's Karstu area, in search of caves. The Linnanmäki is a high hill and cliff in Karstu, and the book Suomen Luolat notes that there are two caves on the hill. One was supposed to be inaccessible without climbing equipment. But as usual, the coordinates were inaccurate, so I ended up going around the entire hill, and I think found the other cave plus four other small roof/shelter caves.

Looking for bunkers and all we found was SHIT
We drove in two cars to south end of the Porkkala peninsula -- 50 minutes away -- to explore three bunkers there. The best map that we have of the abandoned Soviet-era bunkers comes from Lynx, the local orienteering club. Unfortunately, this time their map oversold what was to be found at the location.

On our search for thermal baths in Iceland lead us to Hjalteyri on the northern shores of Iceland, north of Akureyri. We found an abandoned fish factory with storage tanks for fish oil and herring. It was fun to explore, luckily there was no rotten fish smell left :-)

Deadly bunker trap
Well, that was dangerous. We're very careful when we visit blown-up bunkers. But, we did not expect intentional traps, at least not recent ones. Next to a bunker in Siuntio, Jarmo almost fell into a 5-meter deep well that was covered with fresh tree branches. Would he have hurt himself if he fell in, or even if not, would he have been able to get out if he was alone? Who does this sort of thing?!

Since my foot didn't like the walk I did few days ago, an obvious thing to do was to go try more quarries, and this time climb a fence. Without noticing that the fence would have ended if we had walked 10 meters further.

Ruins of the Dalsvik Mansion Gazebo
Today we visited the ruins of a gazebo in Laaksolahti (Dalsvik). The gazebo, or pavilion belonged to the Dalsvik Mansion. If all this sounds funny, in Finnish place was called "Laaksolahden kartanon huvimaja".

Can't find the Österbacken Quarry
There's supposed to be an old quarry in Juvanmalmi. But I kept going up and down near the coordinates, but found nothing. Wrong coordinates? As the darkness came, I did manage however to put my painful foot to a hole in the ground, have it get twisted, and stuck.

Österbacken II
In better daylight and with Jarmo's help we now found the quarry. I must have walked 20 meters from the quarry wall (a 10+ meter drop, btw) yesterday.

Kasaberget cave and abandoned concrete houses
I was searching for a place to visit this Sunday... with pretty much the only requirement being that a teenager would be interested in going. We ended up going to Kasaberget in Kirkkonummi.

Ruins of the Bemböle Watermill
Can you drive by something for 20 years, and not be aware of the wonders just few meters from the road? You can. I had not heard about the Bemböle watermill ruins.

Dead Cat Margarine
Dead cats were blended into margarine and fed to humans. We're going to a secret, abandoned tunnel to meet the ghosts of the cats. But it won't be easy to get there.

Abandoned railroad tunnel
Today's evening excursion was to an abandoned railroad tunnel. The tunnel is 600 meters long, and in the middle of everything, at a place I've been many times, but I had never heard about the tunnel before.

Monttukrouvi
This lazy Saturday's program for me and Janne was to visit some of the bunkers and moats around Helsinki's WWI defence structures. There are plenty of these structures, sadly all slowly rotting away. Historic sites, officially almost forgotten and certainly not cared for.

OpenStreetMap
When skiing or hiking at a new place, suitable maps are essential. These maps can be hard to come by, however, and most GPS maps do not contain information about walking paths, ski slopes or lifts. OpenStreetMap, however, has a lot of good information, and I have been using it in off-piste skiing, finding ski areas, and hiking around the world.

Bunker Bouldering
A blown-up bunker. Debris. Darkness. Bats. Concrete rising to the heights. Walls hanging where they should not be. An ideal climbing place, if it wasn't for the grim past of this place and the morbid pictures of soldiers.

Have ice axe. Will travel to London to go ice climbing. My cab driver thinks that is the weirdest thing he has heard his customers do. I think that if it is true, then his rides have been pretty boring.

Middle Earth
Desperation, n. Travel to the end of the world in search of snow, and then find none. Lose your favourite tools, the skis. So desperate that you consider taking up heli-biking, but end up gliding on your butt in an imaginary world instead.

Ich bin ein Berlin(ski)er
The Berg - a creation by architect Jakob Tigges - is the latest source of pride for Berliners. This artificial mountain covers almost the entire Tempelhof, an old airport. A park like no other. And I am in Berlin to make the first descent!

Midnight Sun at Riksgransen
Many of my friends are regulars at Riksgränsen. But I had never been to this place that calls itself "Sweden's most legendary ski area". The legends are true. It is an amazing place. For starters, we were there in midsummer, skiing at midnight. In bright sunshine! The ski area is far above the arctic circle, and for about two months in the summer the sun does not set.

Ice Climbing in Espoo. In June.
It is Sunday, +10 degrees, raining heavily, and it is the middle of summer in southern Finland. What should I do? Go ice climbing in Espoo, obviously.

Two Feet High
We went to Matinkylä, southern Espoo today. One of the largest shopping malls in Finland, Iso Omena ("Big Apple") is located in Matinkylä. But they are also known as the site of M2, a mountain with icy slopes even in the middle of the summer. The steep slopes of M2 rise a whopping two feet above the surrounding landscape, scaring skiers and mountaineers alike. Indeed, very few climbers have climbed it.

Moominworld Cliffs
If I have to spend eight days per year in Moominland, it is clear that I need to come up with something interesting to do there. How about skiing down the President's Cliff? Fifteen meters of near vertical rock. Too bad I forgot my ice axes, because the return was even tricker.
