We will be arriving in Alesund on cruise ship around 8am till 5pm. Has anyone taken a bus trip on the paths of trolls? Will it be easy to walk from the dock to rent a bus tour or is there public buses that can take you there? Since weather is so unpredictable in that area we thought of waiting till we get there and maybe getting a bus. Or is it better to rent a car and do the drive ourselves? We will greatly appreciate any suggestions or tip. Thanks!
