Packing for Lofoten Islands in 2 weeks. Any local tips on current trail conditions, midnight sun, or hidden gem hikes??

Hey! I am finally fulfilling my dream of visiting Lofoten islands. I will be there for 10 days mid-end of June.

I've already done a ton of research, and have a draft of the itinerary ready, but I would love some advice from people who have been there during midsummer. Some of the questions I'm hoping to get insight on:

1. Trail conditions and mud: I know that the weather is incredibly unpredictable. Should I expect heavy mud on trails? Any tips for packing?

2. The midnight sun: is it worth going on hikes during the night? How to best manage sleep? (sleeping in a tent).

3. Hidden gems: what are the best lesser-known hikes?

Thanks in advance!
