Wikidirections is a wiki to help you get from A to B. We're a human mapping service, but with a twist. Google Maps will give you (sometimes) precise driving directions, but they won't tell you which is the cheapest, or safest, or most scenic, or quickest way between two points. Should you take the train from Vienna to Salzburg, or is the bus cheaper? That's where Wikidirections comes in. Wikidirections is geared towards world travelers, written by world travelers. We won't tell you how to get from your house to the drug store, but we will tell you, for example, how to get from Spain to Morocco quickly, cheaply, and without getting ripped off. While Wikitravel's focus is on the destination, Wikidirections focuses on the journey itself. [more inside]
