Loreto & Bahía Concepción
Puerto Escondido's snug harbour, the Loreto islands, and Concepción's long, sheltered bay.
Bahía de los Ángeles
Remote Midriff anchorages among scattered islands — few services, strong currents and big whales.

The mainland side's boatyards and summer storage — the usual jump-off for crossing to Baja.

Cruising Sea of Cortez
The Sea of Cortez is desert cruising at its purest: volcanic islands, turquoise coves and whale-rich channels running up the inside of Baja, with more anchorages than boats. It is remote and short on services, winter northers blow down the Sea for days, and summer brings heat, sudden squalls and hurricane risk. Depth comes from GMRT bathymetry, with community-mapped navaids, hazards and marinas — offline, where the fuel docks are far apart. This region covers the Baja California peninsula, the Sea of Cortez, Pacific Baja and the crossing from Cabo San Lucas to Mazatlán.

Questions
When is the Sea of Cortez season?
Most cruisers sail the Sea from late autumn to early summer. Hurricane season, roughly June to November, sends many boats to haul out at San Carlos or Guaymas, and winter northers mean picking anchorages with good northern shelter.
Does it cover the crossing to Mazatlán?
Yes — the Cabo San Lucas to Mazatlán crossing sits inside this region and overlaps the Mexico — Pacific region, so either chart carries you across.
Will it work in remote anchorages with no signal?
Yes — fully offline once downloaded, which is the reality across most of the Sea.
