the peak. Trips last around five hours and leave from the Loreto marina, with guides shaping the route around that day’s sea conditions and wildlife activity. Fin whales, dolphins, sea lions and manta rays may appear along the way. Sightings are never guaranteed, so flexibility in your dates often matters more than a packed itinerary, and because the boats are small, the January-to-March weeks fill up early. Their season-by-season whale guide explains what each stretch of winter tends to bring.

The five-hour guided scuba diving tour runs every month, with two dives at sites chosen
from around Coronado, Carmen, or Danzante Island inside the national park. Divemasters
pick the island and the sites according to sea conditions and diver experience, and tanks
and weights are included.
Beginners have a narrower window. Discover Scuba Diving, a supervised PADI introduction
that needs no certification, runs from May through December and is capped at 12 metres
(40 feet). Travellers who want to leave certified can take a three-day Open Water Diver
course or an Advanced Diver course, both offered year-round on the tours page.
Many divers favour roughly August to October, when the Sea of Cortez is at its warmest and
clearest, with visibility that can top 60 feet on a good day. Winter water from December
through March is cooler and calls for a thicker wetsuit, with temperatures swinging from
the mid-60s in winter to the mid-80s in late summer. Their guide to diving the Sea of Cortez
is the place to start if it is your first time.
