Sea of Cortez
Location: Cabo San Lucas
Cabo is home to some amazing diving. Most of the diving here is around the Land's End peninsula that pushes out into the sea of cortez. All of the sites around land's end are just a short boat ride from the Cabo marina. The water is clear and there is a huge amount of marine life. My favorite dive here was Land's end, which is the very tip of the peninsula. It's one of the deeper dives here so it's usually done first. Here you will see huge schools of fish, sting rays, as well as mobula rays. Pelican rock is another good dive site and is a little shallower so sometimes it is done as your second dive. Here you will see angel fish, sea horses, schools of bait fish, and the rock itself is covered in nudibranchs. A unique feature you will see while diving in Cabo are sand falls. Sand from the beaches and surrounding desert wash into the ocean and build up on ledges, once enough has built up it begins fall off the ledge into the deeper water and it creates an effect that looks like a water fall. It's cool to see and can be found at numerous sites around the peninsula. There are a number of dive ops to choose from, and most of them do day trips to Cabo Pulmo and the Gordo Banks as well. I would recommend skipping the Gordo Banks and doing Cabo Pulmo if you are looking for a day trip. Gordo Banks rarely has the schooling hammerheads that you are going there in hopes of seeing. It is a blue water dive where if there isn't sharks, which there usually isn't, then you end up just floating around in the water column looking at nothing. On the day I went we didn't see sharks, but we were lucky enough to see a couple of mobula rays, and a large marlin during our safety stop.
Topside: Cabo has great restaurants and is famous for it's night life. It has excellent bars and clubs. Cabo has great beaches as well. Cabo is also world famous for it's sport fishing, and fishing for a day on a panga is a must. There are few places where the fishing is so good for such a cheap price.
Cabo makes a great dive vacation. If you are looking for a good inexpensive dive trip, and are looking to change it from somewhere in the Caribbean, Cabo is a great choice.
