Just started planning our excursions; these look pretty good:

Hellesylt - Overland Tour to Geiranger with the Briksdal Glacier

Longyeargen - Glacier Hike on Larsbreen

Honningsvag - Deep Sea Rafting and Ice-Bar

Gudvangen - Overland Excursion to Flam

For the cities of Tromso, Bergen, and Oslo, probably just take taxis to tour unless anyone has some good recommendations.
