Located in the heart of Mongolia, Mount Khuiten is one hard mountain to get to. Straddling the border of Russia, Mongolia and China, and reaching 14,350 feet (4,374 meters), Mount Khuiten is tiny compared to Everest and K2. Still, it sits in the remotest part of Mongolia and is the tallest peak in the country. You need to be fit if you're going to climb Khuiten, although trekkers can easily explore the area around base camp. Because of its remoteness, you should keep the weight of your gear -- which should include hiking boots and mountaineering boots -- at 33 pounds (15 kilograms). Although the climb isn't difficult for the locals, it is technical, and requires some skill. The route to the top isn't exactly steep, but it is scarred with crevasses from the Potanin Glacier, so watch where you step.
Because Mount Khuiten is one of the least accessible mountains on the planet, some local adventure groups will shuttle you to the mountain using camels [source: Ke Adventure Travel].
