Orcas and mobulas

Orcas and Mobulas Liveaboard Expedition!

In the Sea of Cortez

We welcome you to join Jim Abernethy for the journey of a lifetime into the Sea of Cortez as we experience the friendly pods of Orcas as they feed on a variety of animals, including the beautiful mobulas rays! Our small groups of 6 ensure intimate experiences with the orcas and a variety of aquatic wildlife.

During this time of year, deep upwelling ocean currents cause the Sea of Cortez to become a hive of activity. This is a true ocean safari, and aside from pods of orcas and mobula rays, there are endless opportunities to see rarely seen ocean dwellers, from blue, fin and pilot whales, sea lions and thousands of dolphins, just to name a few!

While we snorkel and free dive with the mobulas and orcas, we get plenty ocean time on these trips. The scuba diving can be a real treat as well especially for night dives and experiencing some of our favorite dive sites, including those at Cabo Pulmo UNESCO World Heritage Site and National Park. This amazing dive location is the most protected area in the sea of Cortez and the abundant marine life found there, you will never forget.

Jim Abernethy’s Scuba Adventures



The Nautilus-owned SeeCreatures Dive center is located right in the harbor in downtown Cabo San Lucas and is your home away from home. We encourage you to fly in early and allow us to arrange for some local diving.
Your trip includes a complimentary Backscatter lesson. Our photo pros will coach you on how to get that perfect underwater image, help set up, service or repair your camera gear, assist with camera rentals and accompany you on our complimentary warmup dive. You are welcome to drop your bags off and check-in whenever it’s most convenient. We ask that you please be at the dive center by 4 pm for the pre-boarding health check. This trip is predominantly focused on snorkeling and freediving, however, if you would like to dive you will need to bring your own gear.

We have full rental gear available and can get you suited and booted. Enjoy a nice evening walk, arriving back at the dive center by 7 pm for the safety video and boarding the boat at 7:30 pm. Settle into your cabin before enjoying a delicious dinner as we cruise towards the Sea of Cortez.
On your first day out at sea, we’ll be heading out in search of the mobulas. Baja Expeditions has been doing this for 47 years and our crew is comprised of pioneering old-timers who know these waters, and its wildlife, better than anyone.

Anyone who is interested can get out and have a freediving lesson; we’ll have you descending to 30-ft by the end of the day. For a more relaxed affair, you can opt to spend your time onboard relaxing on the sundeck with a good book or soaking in the hot tub. We also have kayaks and stand-up paddleboards.
For at least two days of the trip, we will be using an aircraft to provide aerial spotting to maximize your encounters with the mobulas and, hopefully, orcas. Our pilot specializes in finding orcas and is the very best in the business; he’s been working with Captain Mike for 15 years. The best place to find them is in the triangle between Espiritu Santo, Carpenter Rock on the west side of Cerralvo, and Las Ventanas on Baja, and we will be focusing our search on this area. Be patient, as it might take ten splashes for the mobulas and orcas to allow snorkelers and freedivers into the middle of the pack, but you’ll be rewarded with truly spectacular encounters.

We’ll take you out in groups of six for two hours at a time, before swapping with the other six guests. After a delicious lunch on the deck, we’ll head back out on the water again in the afternoon.
For the next couple of days, we’ll be back on our own again to look for mobulas and orcas. In the evening, you’ll have the chance to see the mobula rays in a different light. There will be the opportunity to go snorkeling at night in a calm, protected bay, where we will suspend lights off the bottom of the boat to attract swarms of mobulas. The mobulas come in to feed on the plankton exposed by the lights, providing a spectacular show against the inky ocean. If you’re a certified diver with your own gear, we can also arrange for you to go night diving.
On the final day, you’ll have the opportunity to dive or snorkel at Cabo Pulmo World Heritage Biosphere Reserve, home to some of the fishiest waters we’ve come across (over 6,000 species and counting, to be specific).  
After a final breakfast we’ll disembark the boat in Cabo.
