I just posted this in the Lights and Nav thread. It should probably be here really.
"I've been from Mulege to about half way between La Paz and Loreto but that was in 2002 - I'm sure there are contributers with much more up to date info for that area.
As for the Midriffs, I am working with a student at Prescott College to create an information clearinghouse for small-craft users (paddlers and open boat sailors). We hope it will be up and running by December. It will probably appear as part of my website at: www.kinopangas.org
Here are the places I recommend to:
Novices (day trip experience, no roll, easy navigation)
Loreto and the Marine National Park (with a guide preferably)
San Carlos bay
Intermediate level (Some multiday experience, have roll, coastal navigation)
-Sonora coast north of Kino Bay to Isla Tiburon and around the south coast of the island
-Sonora coast from Estero Tastiota to Catch 22 beach (San Carlos)
Bahia Los Angeles and Islands
The coast from Puertocitos to Bahia Gonzaga
Baja coast from Mulege to la Paz
You name it...
That's the Sea of Cortez. I like the Yucutan coast and the fresh water lagoons towards Belize."
