The road leading into the base is open. You can just driven in. As I was leaving a crowd of locals showed up in several vehicles. Sunday outing? I waved and drove past. They waved back. Friendly enough. However a visit here should not be taken lightly. It is a dangerous, as in life threathening, place.
According to accounts on the internet, visitors are tolerated. The border police show up sometimes and will stop you and ask for your papers. They will probably take down your details but apparently will allow you to carry on with a warning about the land mines.
The base featured in Aband0ned Arch1tecture on TV. There are also a few websites about it including a w1k1page.
This is a sat image of the base from g00gle earth - credits to g00gle.
You can see where the runways and taxi ways lead into the mountain in the image.
The border is not accurate on the image above so watch where you go. As far as I know the ends of at least one of the two main runways crosses the border. The other gets extremely close to it, so steer clear of there.
Road access to the 4th tunnel shows up as passing through Bosnia on some maps - not so above. I would suggest against verifying this on the ground. Access to this entrance through the network is dangerous as there have been cave ins at this end. This really is not a place you want to be calling for help from, not that you can make a call when you are underground ... its a bit like space ... no one can hear you scream!
Funnily enough, there are two aircraft flying over the base in the above image, but perhaps its not so strange as it must be a highly visible waypoint from the air, even if it isnt an official one.
Oh, and over on the top right of the image is the M5
Maybe I was just west of Birmingham after all
