No reservations but If the docks are full you can usually get a slip at the Anchorage Inn Marina or anchor out in Silver Lake
Fixed docks, restrooms 1 block away, no showers or other amenities. First come/first served. Some boats have trouble tripping electric. Sandwiched between ferry docks. Large ferries park at night, blocking views. Seniors with National Park lifetime passes pay only .60/ft. Quiet. Walking distance to some restaurants...but need bikes or golf cart rental to see the attractions.
