I sailed there a few days ago from MDR- the previous post is right- one long tack. I don't know how it will be from LB. The mooring at Ishmus Harbor cost $32 for one night. That was on a Sunday night. I imagine Avalon will be more costly, and I've heard it is extremely crowded on the 4th and you have to reserve a spot, unless you are anchoring somewhere. Also bring a kayak or dinghy as the water taxi is $5 per person per trip.
