I'm in the process of planning a trip to Norway and Ireland for mid-May through early June 2019 (3 weeks total).
I'll be travelling with a partner - we'd rather not go out of our way to visit museums, but are into beautiful scenery, easy hikes, and delicious food. We'd also love to do an (organised) glacier hike and kayak down a fjord (preferably with guides).
We won't be renting a car so will need to rely on public transport.
We'll be flying into Oslo. and will have around 7-8 days to explore from there.

At this very early planning stage, I think we'll do a DIY NiN tour from Oslo-Bergen, including Flam railway. I also want to include Alesund and a few nights at the Juvet Landscape Hotel in Valldal.

I'd love some recommendations on places to see along the way, places to stay, easiest way to get from Flam/Bergen to Alesund, and anything in between please.

Thanks in advance
