There is a hotel just outside Andalsnes 5 minutes from the wall, it is on the left and is called Hotel Aak. They sell some climbing stuff and have the guide called Klatring i Romsdal. It is a great gude and has english translations.
Are you sure you want to do the Troll? There are better walls in Norway, and just as high. Kjerag is a much better quality destination, plus you get to watch the base jumpers cos it is allowed there. The Troll is pretty loose and tottering! The Rimmon route is now unclimbable and the Swedish route is nasty in the lower half. I am off to Kjerag on friday, waahh!
