* Aland. Accessible via cheap booze-fueled ferry from Stockholm. Probably the child-friendliest area in Scandinavia. Good steep bouldering in all difficulties.

* Dalarna (Stennaset, Trollbo, etc.) Lots of established problems. Insane amount of boulders. Not described in guidebook, but a taster here:

* Plenty of bouldering around Uppsala / Stockholm. I know nothing. Look on 27crags.
* Gävle. As above
* Sundsvall. Plenty of bouldering up to 8a or so. Nothing spectacular. Easy to find info.
* Umeå. As above.
