Cabo San Lucas, rated one of the top 5 tourist destinations of Mexico, is enriched with a wide range of beaches, scuba diving locations and is home to a myriad of marine wildlife including rays, birds, sharks, huge schools of jacks and other tropical fish.
There is a good chance of seeing Mobula rays(smaller family member of the giant manta).
We have a small sealion colony here in the local dive sites, we can see the playful Sealions in most of the months, if lucky we can even see them chasing huge schools of bait ball mackrel.
