SW Florid hasloads of great anchorages. Hear are three of my favoriites are:
Boca Grande- A bayou you enter from the bay side of the barrier island and tie stern to the mangroves with a bow anchor
out. Tie your dinghy
to the county dock
and walk a half mile to the tony little town. Might be a little tight getting in. Watch the tides.
Cayo Costa State Park in Pelican Bay- Room for a hundred boats. Tie you dinghy
to the state park dock
and walk to beach. Also tight getting in- stay close to shore.
Ft Myers Beach- A mooring
field, not an anchorage. But reasonably priced and the beach is a 1/4 mile walk away.
And the link to Southwest Florida Anchorages is great. I used the print version many years ago and the on-line version gives the same information.
