If you would like to dive with sea lions and have the chance to see Mobula Rays, Scalloped Hammerheads and other sharks, huge schools of Jacks and bait balls, as well at Tuna, Wahoo, Eels, Jawfish, many Dolphins; then this trip is for you!  This is the Sea of Cortez, between the Baja California Peninsula and mainland Mexico.  Some of you joined us in the Midriff Island area in the Sea of Cortez a few years ago.  This is farther south with a special itinerary departing from La Paz.  In January 2020, a few of us went on a land based dive excursion from La Paz, and dove with the Sea Lions at Los Islotes.  It was one of my best dives ever!  We are going back to dive with the Sea Lions again and see much more from the comfort of a great live aboard!  AND in October we can see the BABY SEA LIONS, born in the summer months!  Water temps are warmer (between 79 – 81 degrees F) and air temps are in the mid 80’s during the day.  This is also the time of year the Mobula and Cow Rays migrate, we are almost guaranteed to see schools of them!  Beautiful!!

We’ll be diving from the MV Valentina Live Aboard,  a 135’ long live-aboard dive vessel based in La Paz.  She has a “superb” rating, 15 years of experience, a professional and experienced crew, delicious meals, photographer friendly, built for diving, cabins with private bathrooms, showers, and A/C.  She departs from La Paz, a 2 hour transfer from Cabo (SJD airport).  It is very easy to fly to Cabo, Mexico!

I have ALWAYS wanted to return to this area, as it reminds me of Galapagos, but not as pricey!  The Sea of Cortez is a diver’s paradise.  A unique ecosystem and overall natural beauty, it has earned status as a protected UNESCO World Heritage Site.  Come see firsthand why this sea is called the “Aquarium of the World” with all of its natural wonders!
