Re-visiting the Vienna flak towers
​I was in Vienna already in 2018, but for 2020 Janne and I toured the Vienna museums befor e heading to the ski resorts in Austrian alps. This allowed a new visit to Haus des Meeres, the refurbished bunker-turned-into-and-aquarium, and visits to three other bunkers.

Nobel's blasting tunnels
This seemed like a good time of the year to go explore the start of Nobel industries in Vinterviken. Bunkers, tunnels, testing grounds, and simple factory buildings.

Seah Im Bunker
Once my meeting ended, I wanted to use the couple of hours I had for exploration, and got Tero to join me. I've already covered the Singapore caves and skiing... what remained was bunkers!

Moon over the missile base
I felt the urge to visit odd places, and an old Nike missile base seemed to fit the bill. But, I was quickly losing light on the only day that I could do this. Then the shortcut turned out to be non-passable, and the short hike turned into a 8-kilometre trek on steep hills. In darkness. And, somebody had removed the ruins. Trip ruined? Not quite, the moon and the sea were wonderful in the darkness.

Military tunnels deep inside Mali Hum
The taxi drivers are a great information source. This time I asked about a hole in a cliff face, and got all the information I needed to visit it later. And it should be a safe place to go to...

Siuntio bunker tips from Dutch tourists
Having researched the locations of the Russian bunkers in Porkkala for years, I was surprised to learn the location of another bunker from Dutch tourists on their first day of visiting Finland. They pointed us to a small bunker few hundred meters from the large one we had visited earlier, based on their geocaching explorations.

Hiking to the abandoned missile base
The base is not easy to find; there's a lot of tours on sale to visit the military wonders of Vis, but little actual information. I discovered the location of the base by looking at Google Maps satellite photos, but the Secret Croatia blog also helped...

Hunting for the Sarfvik Secrets
I went on a long bike trip today with Jarmo, to explore the Sarfvik area in Kirkkonummi. This large area of farms, forests and seafront is blocked for public road access by the local residents. Why? You can still explore the area on foot, but the walks are long. But in the summer biking is an option.

Corporate sauna in a Russian harbour
I attended a workshop at a private corporate facility in Kirkkonummi, and it turns out that there was both a very nice sauna, swimming place, as well as ruins from the Russian occupation times: a railroad leading to a rock, almost disappeared harbour pier. Nice surprise!
