Arizona

Here are some links that I recommend to get a better picture:
 

Arizona and the Outdoors: Nationalparks The official site for all the great parks in the US. Grand Canyon The official (and best) GC site on the web. CanX The best rafting company for the Colorado. One of the few with oar-only trips! Arizona Guide & The American Southwest The two best guides to the state on the web. Arizona Highways Online My favorite magazine. There's the perfect mixture of high-end photography and stories for reminiscing. You can order this lovely publication even internationally! Bureau of Land Management Arizona Helpful for some inside information and the backcountry permits. Newtimes Need to check out what to do in Phoenix? This is the official "What's happening guide" to the city.

And the gear for all of that: Mountain Hardware Best stuff to wear. Gregory Best (American) stuff to put your stuff in. Deuter Better (European) stuff to put your stuff in. REI Hiking store Most complete store (online and offline) and one of the cheapest ways to get the above. The Summit Hut The easiest way to shop in AZ (or elsewhere). Located in Tucson, AZ, this on-line and catalog store's got it all! Baechli Bergsport The best place in Switzerland for moutaineering equipment. They also got stores in Zurich and other big Swiss cities.
