Are you going just to boulder, or to do routes and maybe some bouldering in the evenings?
If the latter, there is loads to have fun. Boulders by the beach next to Kalle campground, lots below Presten on the way down to Henningsvaer, more at the turning from the main road, on to the smaller road to Henningsvaer.
I'm not sure if there are any topos. Some photos on Ben Moon's website of his problems.
If you are going to Lofoten just
to boulder, you are beyond help and should seek professional psychiatric counselling.
