I've anchored several places inside the pass but no designated anchor
areas. One likely spot is west of the ferry
launch on the north side of the river. Right west of the launch you can dinghy
ashore to a convenience store or bar/restaurant. If you go south on intracoastal to atlantic avenue bridge there is a deep finger that shoots off to the east just before the bridge. There are some private mooring
balls there that are most often empty. Toward atlantic beach provisions abound, propane
and groceries available. Lock dinghy
or have someone drop shore party off.if you wanted to go all the way to jax they have 2 locations with free 3day slips. One at riverwalk and one at jaguars stadium.
