Sweden is full of boulders, new stuff being developed all the time. I've had some good sessions around linkoping, and norkoping, plus all over dalarna (county)
For an awesome quick trip how about kjuge, the koping's then hop on the boat from stockholm to aland to finish up.
Top tip don't be shy contacting clubs/local walls for the info on the new areas, you'll probably end up with a super psyched swede as a guide
and take some good deet!
