There are some people who are determined to not wear clothes in the great outdoors. There are the people who do naked rock climbing, people who hang out on a nude beach (or play volleyball in the buff on a beach like those I saw once in Greece), people who sky dive nude, dance in the nude, go on cruises in the nude, and, like this German guy I read about, people who prefer to hike in nothing but a good pair of shoes.

Even jail time is not dissuading this German fellow from his naked hiking habits, according this Reuters article. This fellow was put in jail for ten days for in the buff walkabouts, but has vowed that he will continue to hit the trails without clothes even though it is against the law. Perhaps he sees a double standard? Hiking in the nude breaks Germany's indecency laws, although nude beaching it is okay in designated areas.

Interestingly, Germany has a German Nudist Association which is part of the German Sports Association. Nudism can be traced back to Germany as a way to be healthier, so the association fits the idea of fitness. This membership has created an increase in nude hiking love. Nude jogging also has a following, but loping along in just socks and running shoes also lands a fine.

In a way, one could say that if there are nude beaches there could be nude forests and nude mountains for those who like to scale cliffs. Whatever they do, I hope they're using a decent sunscreen.

Many seasoned backpackers are aware of Bolivia's "most dangerous road" in the world. If you want that kind of excitement--and perhaps more so since this is a hiking trail--check out China's Huashan trail, a very doable itinerary if you happen to be in Beijing for the Olympics.

To do justice to the experience, see the pictures here and here. Words can't describe some of the harrowing sections of the trail--which, again, is suppose to be a hiking trail. That means no climbing gear is available. I can easily see people falling to their deaths, and apparently because of China's less-than-stellar press freedoms, many deaths are kept quiet.

To get there, fly into Xian, which can take up a whole series of posts by itself (terracotta soldiers are there, for one). Then take the minibuses that run from the train station directly to Huashan. Or you can take the train, which drops you off some 25 km east of the mountain.

Two months ago I went rappelling in the Hocking Hills State Forest with Earth, Water, Rock Adventures Ltd.

I was pretty proud of myself that all I ended up with was a scrape on my calf when I slipped on some moss on my first time down the rock face.I could have scrapped a lot more if I had followed the thrill of nude rock climbing.

There is a trend where people cast off their clothes to experience nature from high places in the buff. The trend seems to have started in California, but has been transported to Great Britain as well.

The friend who sent me the article to the naked Barbie on the dash board story sent me this article about nude rock climbing. All I could think of when I read this story was that Jerry Seinfeld episode where he had a girl friend who insisted on being nude as much as possible. Jerry wasn't too thrilled, particularly when she attempted to open a pickle jar.

Nude rock climbing would probably really set Jerry on edge. It certainly brings being naked to a higher level.

Dean Fidelman, a rock-climber and the guy who took this picture has made a calendar dedicated to this endeavor. The project is called Stone Nudes.

His work reminds me a bit of Spencer Tunick's, another artist who sees the human form as one that lends itself well to being photographed sans clothes in nature. There is a simplicity that is very alluring.

Travel health and the emerging specialty of "wilderness medicine" have obvious overlap. Dr. Paul Auerbach is one of the leaders in wilderness medicine: helping found the Wilderness Medical Society, co-author of A Field Guide to Wilderness Medicine and numerous journal articles and serving as faculty to the Stanford Fellowship in Wilderness Medicine.

His blog, Medicine for the Outdoors, is celebrating the two year anniversary. For those who haven't yet had a chance to visit, it is filled with practical information and advice for those exploring their environment and wanting to come back from the experience in good health. Travel and expedition medicine is the focus of my career and I find myself citing Dr. Auerbach's work and information, in my work. He is one of the pioneering physicians who helped elevate this field of medicine to a new and unique specialty.

A visit to his blog will allow the reader to learn about things from jellyfish stings and dislocated shoulders on the trail to malaria medications and outdoor recreation. This is truly an opportunity to read, first hand, the information from a leader in wilderness and expedition medicine. I highly recommend a visit to his blog, if you get a chance. Oh, and don't forget to congratulate him on his two-years of dispensing great advice!

Here's another version of canopy tours, much different than the ones in Hocking Hills, Ohio and near Kuala Lumpur. At the Ysterhout Gorge in Magaliesberg, South Africa, trees are sparse, but the gorge is mighty. This is a well-done edited version that shows each step of the experience. The scenery is gorgeous. The family in this video consists of a young girl as well. You really know how much you trust a tour guide when you send your child flying along a cable, feet dangling high above the rocky ground. There's a point where my heart would jump. Part with fright, part with their excitment--and I'm the one who once took my 3 month-old on long boat rides in Thailand, passing him above the water while he was strapped in a car seat carrier. Here is a resource to find canopy tours in South Africa, plus a Gadling post from former blogger Erik Olsen that presents options in other places.

Politics aside, this is actually pretty spectacular. Chinese mountaineering team, including a woman from Tibet, took the Olympic flame to the top of the world today, AP reports.

The team used torches designed by rocket scientists to take the flame to the peak of Mount Everest. Fueled by propane, the flame burned brightly in the frigid, windy, oxygen-thin Himalayan air thanks to technology that keeps rocket motors burning in the upper reaches of the atmosphere. The flame was carried most of the way in a special metal canister. As the team neared the summit, they used a wand to pass the flame to the torch.

Wow. All this effort just to say "we did it."

The Mount Everest climbers were struggling for breath in a live television broadcast as five torchbearers each shuffled a few feet before passing on the flame to the next person. The final torchbearer, a Tibetan woman named Cering Wangmo, stood silently on the peak with her torch while other team members unfurled small Chinese and Olympic flags. They then clustered together, cheering "We made it," and "Beijing welcomes you."

One would almost think that China and Tibet are best friends. Almost.

From San Francisco to London and Paris to India, protestors are taking to the streets to demonstrate against China's hosting of the Olympic Games. Angered by the Chinese government's refusal to meet with the Dalai Lama, as well as the continued suppression of human rights in potential breakaway regions, the world is seeking to punish China on the eve of its long-anticipated coming out party.

For travelers on the ground in China, independent tourism has never been more difficult, especially since parts of the country have now been entirely closed off to the outside world. Following wave of violence that commenced on March 14th, the Chinese government has entirely barred tourists from entering Tibet. As a so-called 'autonomous region,' non-Chinese nationals must obtain special entry permits for Tibet.

Sadly, it's looking like the 'Roof of the World' may remain in relative isolation until the Olympic Games have passed, which is a huge blow at a time when tourism in the region was beginning to flourishing. Here in Japan, this was highlighted recently in the news when Mr. Yuichiro Miura, the 75 year-old thrill seeker who once skied down Everest using a parachute as a brake, announced that he was changing his Everest climbing route.

Afraid of heights? Don't watch this video, shot along El Caminito del Rey, a mountain walkway near Malaga, Spain. This narrow, gut-wrenching path is only 3 feet wide, pinned along the side of a gorge, nearly 700 feet above the river below.

Originally built in 1901 to allow local workers to cross between two nearby waterfalls, El Caminito has recently fallen into a sad state of disrepair. Many parts of the walkway have completely collapsed, leaving nothing but a metal beam and a wire between you and 700 feet of nothing. Not surprisingly, there have been a number of deaths along the trail, and the local government has tried to seal it off.

But for some adrenaline junkies, a warning sign, tall fences and the prospect of a fatal slip-up is nothing but a challenge. Check out this video and watch one man laugh in the face of death.

What is it about Spain that inspires thrill-seekers to the utmost feats of poor judgment?

If you are an outdoor aficionado, you may already be familiar with Wend. The outdoor magazine based out of Portland, Oregon fills its pages with stories from around the globe that peak the interest of not only outdoor enthusiasts, but anyone with a wanderlust. The latest issue covers a trip through Iceland, volunteering in Indonesia, trekking Afghanistan and surfing the Great Lakes; that's what I call good reading material.

Being the eco-friendly souls that they are, the Wend crew finally put the magazine online, making all of the articles accessible via your computer. You can still buy the print version, but if you are out traveling -- or just want to save on paper consumption -- the new online version is just as satisfying. And it's free.

Check out the virtual version of the latest issue here. And if you are feeling truly inspired, shoot them an email and pitch a story.

Sure, we've all thought about it and some of us do it often. Getting high on your holiday trip can be pretty fun, in fact. I mean really high, above 11,500 feet (3500 m). Not everything cool is on a beach at sea-level. Ruins in the Andes, trekking in the Himalayas and chasing back country powder are a few things you have to get high, to do. These trips are all "dream vacations," so why risk a problem with altitude sickness?

High altitude is considered to be 1500 - 3500 m (4950 - 11,500 ft) while very high altitude covers 3500 to 5500 m (11,500-18,050 ft). Anything above 5500 m falls into the extreme altitude category. Altitude sickness is not related to physical fitness and can have some deadly consequences, if not recognized and treated promptly.

Accute Mountain Sickness generally includes symptoms of headache, worse at night or during straining, nausea/vomiting and dizziness. The symptoms are often described as a "bad hangover".

Some conditions associated with more severe forms of altitude sickness or AMS (acute mountain sickness) include HACE (high altitude cerebral edema) and HAPE (high altitude pulmonary edema). These conditions involve swelling and fluid accumulation in the respective tissues. Swelling of the brain, as seen in HACE, can present as marked stupor and confusion. HAPE, with fluid collecting in the person's lungs, often starts as a cough followed by progressive shortness of breath.
