Asinara National Park Authority, headquarters in Porto Torres

The Park Authority's headquarters are in Porto Torres, not on the island. Its website is the reference for the park's rules, the list of authorised operators (boats from Stintino, 4x4 tours, walking guides, diving, bike hire) and the maps of the trails. If you want to walk on your own, check there first which areas are open: part of the island and of the sea is strictly protected. The park recommends visiting with authorised operators.
