Family from Hawaii is visiting us in North Idaho, what are some places I can suggest for them to go . It will be in June and they are in 50s?

There's a Naval History Museum at Faragat state park that's pretty cool. The park was a huge training facility for the US Navy during WW2 and has been converted to a state park since then.

Silverwood theme park is also cool - at least that's what I hear, since I've never been there.

If all of you have passports or passport cards and you live close to the border then consider a day trip to Canada, just to do it.
