Sorry about that - We would like it to be within the US at this time.
Man, you're making this really hard. Napa valley/northern CASedona Glacier National ParkJackson, WyomingAlaska - lots of options there Park City, UtahMaine / Bar Harbor Vermont - again, lots of options Newport RI The Catskills/Hudson Valley Asheville, NCAlso lots of options in the Blue Ridge Mountains The Hamptons/MontaukFinger Lakes region in NYI'm sure there are also a lot of great options in Colorado
H and I travel a ton and our top trips in the US are as follows: Napa/Sonoma, San Fran, skiing in Jackson Hole, New York, Seattle/Portland, Washington.
We liked all the major cities for things to do/great food options and ease for getting to/from.
Napa/Sonoma was my favourite trip because we walked/cycled between many great wineries and basically lived outside for 6 days.
Jackson Hole is a place we go back to every year for skiing. We love the layout of the mountain and the variety of food options. It is also easy to get to. I haven't been during the summer but we were told that the hiking is phenomenal.
