I'm not sure from your post above if you'll have access to a car or not and that will massively impact what you can do but depending on your location if you have a few days spare it's worth heading to the White Mountains in New Hampshire. There is a huge amount of climbing here, including some excellent large cliffs of clean granite.

I've not climbed in Vermont, I'm sure what's there is good, but for a climber visiting from Europe the White Mountains would be a more spectacular location from a climbing perspective. Vermont has better beer though, don't miss anything by The Alchemist, or Hill Farmstead.
It's a year out but if you need a partner I would be down to climb.
A location and if you have to stay there or you can travel for several days climbing would help me give a recommendation. Vermont itself has an area larger than Wales, but it's narrow and has a highway running through it, so depending where you are travel times might not be too long.
