Kronotsky Nature Preserve
You won't just stumble upon Kronotsky Nature Preserve. Located in eastern Russia, this remote wildlife sanctuary lies in the Kamchatka Peninsula -- between the Northern Pacific Ocean and the Bering Sea on its eastern shores and the Sea of Okhotsk to the west.
If you do get to take on this adventure, count yourself among a rare number of people. Harsh weather during the winter months pretty much rules out visits during November through April. Typically, travel companies offer guided tours that involve more than 14 days of hiking and camping, so you better be at nearly peak performance to consider an excursion here. During this outdoor adventure, you can expect to see bears, foxes and more than 200 species of birds, as well as active geysers. The payoff for trekking an uninterrupted nine hours a day -- much of it at high altitude -- is a dip or two in the hot springs located throughout this mountainous region.
