One remark in advance:
All the places listed here we have not yet visited ourselves and therefore can not comment on them. This is only a link collection for all interested. By clicking on the corresponding bar you will get to the permit pages.
When we were in Hawaii in 2000, no permits were needed for either Haleakala or Kalalau Trail.
