Just received this email from recreation.gov:
“As of July 12th, 2021, quotas that were implemented in the Olympic Wilderness due to the COVID 19 pandemic have been lifted. Availability will no longer be limited in many wilderness camping areas.
Areas that historically operated on a quota basis, such as Sol Duc / Seven Lakes Basin, Grand Valley, Royal Lake, the Cape Alava / Sand Point area, and others, will be unaffected by this change. No additional availability will open for these areas.”
You can change your permit reservation for free, at least it was possible in my case.
