Haena State Park and the Napali Coast State Wilderness Park will reopen on Monday, June 17.
Governor David Ige and the First Lady hiked a short section of the trail last week at a community blessing.
Some changes include an online reservation system, which will cap the number of visitors to the park.
There will also be an entry fee for non-Hawaii residents.
The parking lot will have 100 spaces and no parking will be allowed along Kuhio Highway, or people will be faced with a $200 fine.
