Hi there we are planning to ride from Trondheim to Tromso between about May 29 and June 19th (we fly into Oslo May 25th and plan to take the train to Trondheim).

We would like to come back south about June 19 to ride a loop from Andalsnes to Geiranger, Strynrefjellet and Sognefjellet to Lom (if legs and weather permit). And then take the train to the airport to fly back to Canada July 4th.

Question: Should we book our transport south from Tromso ahead of time because its getting close to high season? Will ferry and train tickets sell out?
What would be your recommended way of travelling with a bike between Tromso and Andalsnes?

I am using the Entur app and found the Havila ferry option from Tromso to Molde looks the least stressful (but more expensive so maybe worth it).
Other Entur options involved trains, buses and ferries which seemed complicated with a bike!
Thank you in advance!
Julia
