Well if by remote and inhospitable you understand extremes of climates and access locations – then I may count a few.

A continent and ocean “by invitation only”, Antarctica is also regulated by authority impositions regarding the number of tourists it can receive. You need to fit in some scientific experiment or so, that is the best way to visit – if you can endure the minus 40 Celsius in the Summer time, months of daylight or darkness...or 18-20 meters high ocean waves crossing the Drake or the roaring 40's and furious 50's when coming from South Africa, across the South Atlantic. You can subscribe to my Antarctica posts to keep getting more info.

Then working on the Mojave Desert, with a full body steel harness, on top of a tower telescope at 60 meters from the ground and > 40 Celsius during the day - could also be on such list.

Getting your station wagon pulled out by Park Rangers from being stuck in dry river beds of New Mexico or dancing with it across muddy “roads” in the tropical rain forest of Belize and Guatemala is already soft core – comparatively. Many can do that – as in stealing apples from your neighbors orchards :-)

I never been to the Inaccesibility Pole area in Antarctica though :-)

Joe:

Your question should have been about dowtown LA or Tijuana, not Afghanistan :-)

Good question Joe. I'm waiting to read all the comments. My travels have been pretty tame by comparison to some.

The most inaccessible place I have been to is in a ruined hotel in Paranaque area here in the Philippines. My friends and I went to the ruined hotel to have a photoshoot, but that photoshoot was cut short when an authority arrived and told us to leave. According to him, the ruins are still parts of the hotel and are private properties so we can't do anything there even just take pictures.

I've been to Downtown LA and never felt at risk. I was thinking of stuff like being deep in KR territory in Cambodia, or Area 51 type stuff. Anyone cn walk deep into the wilderness, but some of the most dangerous places are right under your nose. Here in London my friend does what he calls "3am Freak Tours" going round the most scary parts of the city filled with pimps, dealers and bottom feeders of all descriptions. It'd be cool to hear about anyone doing stuff like visiting abandoned soviet test sites, or the Chechen/Russian border. Fron line Basra for a guy looking like a rotarian would fit into that. These are the kind of stories I want to hear. Favellas in Brazil too. comebackalive.com, great website, black flag cafe too.

I really have lead a sheltered life by comparison. Then again we did have war in these parts. Thank heavens that has settled down long time ago.
As far as I am concerned, I was in New York but I really did not think it was THAT bad, I think Americans we were with we more concern what we would get up to :) There was a bit of an incident but nothing worrisome just some drunk who didnt want to leave us alone.
And apparently some parts of Budapest can be very dodgy, however as we walked around through most of them I can atest it was not that bad either. In fact we had quite a pleasant chat with some prostitutes :)

Yeah, in 2003 I worked for a company that sent me to Porec in Croatia and supposedly the owner of a local holiday parc was wanted for war crimes.
I was surprised in Budapest to see all the nazi memerobilia on sale in the army surplus stores. I almost had an incident with some Nazi-looking types when they thought I was looking at them in an aggressive way.
Lived in NYC for three years until 2001 and apart from getting into some drunken scuffles, never saw any trouble. The dealers and pimps leave you alone if you ignore them and walk like you belong there. It's different now - much different, cleaner.
Belfast was a little scary for me as an Englishman in the late 80's. I didn't speak much and grew my hair long so no one thought I was in the armed forces. My sister dated a guy who was in the UDF. Seen some MIBs out in the white sands when I was trying to get my car down a priimitive road, who told me to turn round. Had a gun waved in my face in Italy, but never had anything serious happen, hence he reason for wanting to know other people's stories.

The most dangerous place I went to was the mount Pinatubo area in the Philippines. I took a tuk tuk / rickshaw to go there and agreed a price of 300 pesos. It wasn’t exactly out of bounds, and it was certainly well worth visiting, however upon my return I had heard that taking a private tuk tuk driver could be dangerous as there is simply no one around and with such isolation comes the danger of banditry. I went very, very far from the nearest city, some 30 miles into a veritable no-man’s land. It was truly inhospitable especially when all traces of civilization disappeared beyond the horizon, yet it was also an incredible and very memorably experience. Looking back, it was possibly the most dangerous sight-seeing trip I have embarked on. Fortunately my driver was fine and didn’t turn out to be a bandit, nor did we meet any others, but it really would be something I wouldn’t do again unless I was with a group!
