The premise of your question is incorrect. The Bermuda Triangle is not mysterious. From the Wikipedia article: Most reputable sources dismiss the idea that there is any mystery. The vicinity of the Bermuda Triangle is one of the most heavily traveled shipping lanes in the world, with ships frequently crossing through it for ports in the Americas, Europe,...

At this moment, FlightRadar24 shows more than 30 commercial flights in the area, and that's likely true at almost any time of the day. I'm betting most will survive ;)

The ocean floor. Any other unexplored spots pale in comparison with about 75% of the planet's surface covered by oceans, of which hardly anything deeper than 100m has been meaningfully explored. There are literally millions of square kilometers about which we know nothing except a very coarse-grained depth profile. There could be a hundred sunken Atlantises ...

The fascinating Confluence Project records four visits to (0,0). Visit #1 was by a US Coast Guard vessel that happened to be sailing past, and they took a (bad) photo of the buoy too. Visit #2 is not listed. Mysterious... Visit #3 was by a group of artists (!), who sailed from Hamburg, Germany to Tema, Ghana on a cargo ship. There they chartered a boat ...

There are many long (and long-ish) distance swims known around the world. If you're looking for something medium distance (i.e. not English Channel), you can try International Swim Across Dnipro River in Ukraine - it's 10km, about 4 times the distance of Escape from Alcatraz swim and about 1/3 of the English Channel. Here's the link to the last year's ...

I can answer for Palmyra Atoll, as I happend to have come across this recently. From time to time, the US Fish and Wildlife Service seeks volunteers to work on Palmyra Atoll. The last call for volunteers went out in May, and it's a bit of a commitment: "Volunteers will be expected to work 8 hours a day 6/days per week for the entire ~3-4 months on Palmyra, ...

(Almost) relevant humor - Always remember that Robinson Crusoe is the only person who has every always been able to get everything done by Friday. (1) Work your way through the incredibly long Wikipedia - uninhabited islands entry. (2) NZ uninhabited islands subset . None too tropical. Once you are legally in NZ there are some where you may just row/swim ...

The Freedom Swim is another "prison escape" swim from Robben Island (where Nelson Mandela and many other political prisoners of the Apartheid era were held) to Blouberg, near Cape Town, South Africa. The distance is 7.5km and the temperature is typically around 13°C. It takes place in the Southern Hemisphere autumn (around Freedom Day, 27 April) and is open ...

Probably Somalia. In 2010, there was a Canadian man who disembarked from his plane in Mogadishu claiming to be a tourist, and the officials were in such disbelief that Somalia had a tourist that they detained him and it made the news. An immigration official is quoted as saying that the Canadian was “the first person to come to Mogadishu only for tourism". ...

It's common practice on the iron ore train in Mauritania. The train carries iron ore in huge hoppers. There are no roofs -- passengers either ride with the ore or pay a small amount for a ticket in the passenger car. The scenery is barren desert, the ride is brutally uncomfortable, and temperatures are extremely hot. I rode last summer solo from Choum to ...

I've actually just written a book called 'How to Get to the North Pole' so may be able to help. The first thing to note is that there are several different north poles. The one most commonly referred to is the Geographic North Pole but if you consider the Magnetic North Pole as a viable alternative then that opens up a couple of other options. The North ...

Roads, pretty much by definition, are mapped somewhere. In northern Ontario there are "logging roads" which were made by the logging companies and don't have the same legality as a road made by government (municipal or otherwise.) But if someone got out some heavy equipment and made a road, there is a map somewhere that shows it. It just might not be a ...

There is definitely North America cross continent tours by Canadian Rail although to cross the entire continent you will need to do this in 2 legs. Vancouver to Toronto and Toronto to Halifax. US has similar but also in 2 Legs: LakeShore Limited which would get you from Boston to Chicago and then Empire builder which would get you from Chicago to ...

The 2017 Lake Balaton cross swimming competition is a 5.2km swim in the biggest lake in Central Europe. Registration is 30 USD. Around 10,000 people do this yearly, however very few from abroad, only a few hundred typically. There's a certain bragging right in that :)

There can't be any exact dates for when it's safe because that depends on the (highly variable) water level in the river, which depends on rainfalls. Getting there requires taking a boat, a short rocky hike and swimming through a safe part of the river before you get to the pool itself (source: a TV show I saw). You should only do it as a guided tour, in ...

Lake Ohrid in Macedonia. It's the oldest lake in Europe. There is a traditional marathon every year. It's beautiful, affordable, no sharks and lots of history. I was born there if you need any info feel free to msg me. The marathon is about ~30km and the best swimmers in the world come to compete. Ohrid Swimming Marathon (Wikipedia).

I'm really fascinated by the Vivek Express right now. From wikipedia: ... the longest running train in India, and 8th longest in the world ... runs a total distance of 4,286 km from Dibrugarh in upper Assam, to Kanyakumari at the southern tip of Indian peninsula via Trivandrum Central ... 82:30 hours (almost 4 days). There are 52 halts spanning across a ...

If you haven't had the chance to go to Sun Moon Lake in Taiwan, this could be a great reason for a first visit. It hosts an annual 3-km race across the lake, where swimming otherwise is forbidden. The lake is surrounded by mountains and the whole area is generally amazing. The only potential downside is how time-consuming it is to go there. The easiest way ...

If you're asking specifically about India, I wouldn't advise it! Indian trains that run on electricity get their power feed from overhead lines rather than a 'third-rail' running parallel and inbetween tracks. Most 'mainstream' trains in India now run on electrified tracks with only minority running on diesel locomotives. You might have gotten your idea of ...

In Australia you have The Ghan crossing the continent north-south (almost 3000km from Adelaide to Darwin), and the Indian Pacific crossing it east-west (4350km from Sydney to Perth).

Join or sponsor an Amateur Radio expedition. Many Amateur Radio enthusiasts like to collect radio contacts and postcards confirming these contacts (called QSL cards) from rare and distant locations (called DX). The richer hobbyists will sponsor or join a DX-pedition to some of the more exotic, uninhabited, locations that are rarely heard on the air. ...

Apparently some of the Venezuelan Tepui remain unexplored. Many of them are part of a national park however, and you might need permits to vist (and you couldn't leave a flag there!)

In addition to what Kate said about rivers, it's worth noting that current mapping of even oceans is subject to change, error or re-writing. Late last year a team of scientists was in the South Pacific doing a geographical survey of Sandy Island, 20 miles long and 5 miles wide. There was just one problem. The island doesn't exist. It was on Google maps ...

An other alternative is to fly to Longyearbyen in Svalbard and then use the chopper service to visit North pole from around 15000 Euros. This is cheaper than the cruise trip.

First of all, I'm not recommending visiting Chechnya either. It can be really dangerous. But the real danger is in the other republics in the region, especially Ingushetia. If you're serious in your decision to visit Chechnya - I have "good news" for you - Ramzan Kadyrov (chief of the Republic) is doing his best to attract new tourists to the reconstructed ...

In the U.S. Amtrak is the only long-distance passenger train operator, and on their site you can see a list of all of their routes. The route that looks closest to meeting your criteria is: Southwest Chief -- Runs from Chicago, Illinois to Los Angeles, California, or roughly 2/3 the width of the continent. If you add the Lake Shore Limited route (New York ...
