Where is the number 1 place to go in the US for about a week - anywhere, but more scenery orientated?
What sort of scenery are you looking for? The wonderful thing about America is that it is so varied. Each state is completely different, almost like traveling into different countries. From the mountains of Colorado to the historic facades of Virginia, all the way to the swampy magnificence of Louisiana, you've got so much choice.
Personally? I'm a big fan of the Pacific Northwest. Oregon and Washington are both beautiful states with big, lush forests, bustling cities (Portland and Seattle are both completely awesome), cool coastline, and a whole slew of activities that fit inbetween all of those.
If you're into the desert scene, nothing beats Moab, Utah, for it's sheer awe-inspiring beauty.
Steer clear of the Midwest (no offence meant to Nebraska, Kansas, or Oklahoma) unless you're into rolling hills and flatland. about 10 years ago
West coast - you can take your pick - iether the San Francisco Bay area - with an excursion to Yosemite park and lake tahoe. Or perhaps go to Nevada/Utah - visit Vegas with excursions to the Grand Canyon, Bryce Canyon and Zion national park - (also if you have the time go to monument valley - really cool)
A third option is to stick to Utah - you can take a loop that will include Bryce Canyon, Zion national park, monument valley, Canyonland national park and Arches national park - Absolutaly AMAZING Scenery about 10 years ago
I'm sure there are a gazillion places... but I would say San Francisco as well. Check out their great city and then head up to Napa Valley... and if you have time keep going and check out the Redwoods National Park... home of huge Redwood trees. about 10 years ago
The most dramatic mountain scenery in the States (IMO) is Glacier National Park in Montana. It's not the easiest place to get to, but it's worth it. There's heaps of hiking and river rafting among some of the most beautiful glacial formations you'll see anywhere short of the Himalaya. about 10 years ago
I would go with San Francisco Bay Area as well - partially because I'm from there. But @Scott is right, there is so much to do with in a 4 hour driving radius - beach, snow, lakes, rivers, desert, forest... And if you don't have a car you can still see a lot by taking ferries or BART (Bay Area Rapid Transit). What time of year are you going? That makes a big difference for a lot of places. about 10 years ago
