These buses were conveniently parked only a few yards away from our disembarking point at the cruise terminal .We found that we could choose all 3 routes even though we only paid for the mermaid tour.The routes are denoted by colored signs on the sides of the buses which appear at the pick up and drop off points every 10-15 mins. Very friendly and helpful drivers your only limitation is how much you can cram into one day as they finish running at about 4.30 pm

Brilliant and most cost effective way to get about Oslo. Pick tickets up at the Tourist information centre a few yards from City Hall for free Oslo guides.Just using Ferry (behind City Hall)both ways to Viking Ship museum /Kon Tiki museum all of which is free using the pass more than pays for it.
