The Trans-Siberian Railway: Moscow to Vladivostok, Russia
Cost: This five-night journey will cost you around $590 in second class, which includes a bed and three meals a day. What it doesn't include is that Russian visa, the travel insurance, and tip money for the staff. Still, all in all, that's 10.5 miles to the dollar for the longest train journey you'll ever take.
At over 6,152 miles long, connecting Moscow to the Pacific port of Vladivostok, the Trans-Siberian Railway is the longest line in the world. So if you're into trains, this is the big-kahuna bucket list journey you just have to take. It spans across eight time zones, the Ural Mountains, the largest and deepest freshwater lake on Earth, desolate fields of ice, and Siberian scenery of incomparable grandness. Along with the views, an adequate amount of food is included, and you'll find extra delights like Russian vodka and beer in the railcar.
