The season for the amazing Mobula Rays, also known as Jumping Rays or Devil Rays, begins in April and runs through the end of July each year. The season for the Giant Mantas begins in August and runs into mid December.

We frequently experience the fantastic Mobula rays, also known as Jumping Rays or Devil Rays, in the wild from around April through July. These amazing rays tend to congregate close to Espiritu Santo island. Our Expedition for Mobula Rays is an exciting journey that includes visiting beaches, bays and coves on Espiritu Santo island. Normally, there is also time for kayaking, paddle boards, snorkeling with tropical fish and exploring remote island beaches. We tend to see these wonderful creatures as they jump out of the water during their merging season into larger schools called a fever. Our estimate for seeing these remarkable animals is about 70% during the season.

The Giant Manta season typically runs from August through November concurrent with the Mobula ray season. These gentle, but massive rays, tend to be more elusive, and harder to spot. They rarely jump out of the water. Instead they normally glide serenely around La Reina Reef, which is an hour or two further by boat from where the mobula rays tend to gather. As we are operating in open ocean waters, predicting exactly where the rays will be at any given time is a best guess based on years of experience in local waters. Thus, this experience tells us where to expect rays will likely be traveling and gathering at certain times of the year, but it is no guarantee that we will find them on any given day. Our estimate for seeing these mysterious gentle giants is about 40% on any given day during the season.

As a surprise to almost everyone, the last two years in a row, several giant mantas visited the whale shark park filtering plankton right alongside the whale sharks. This suggests that giant mantas may be expanding their cruising grounds into swaths of water closer to where the mobula rays tend to merge into mega schools called a fever in the months just prior to when the giant mantas arrive.

We provide a large and spacious sailing catamaran, or a 96’ Cruising Yacht, with one or more licensed and certified snorkel boats, licensed captains, and certified guides, typically a marine biologist.

Ground transportation is included along with, wetsuits, snorkel gear, a separate snorkel boat or boats, snorkel vests, towels, private bathrooms, private fresh-water showers, and reef-friendly sunscreen.

An onboard chef prepares meals, which are also included. We provide an array of beverages, snacks, and an open bar. We typically provide a marine biologist as your teacher and instructor. There are excellent areas to lay-out on board and enjoy your cruise. For service quality reasons, we self-restrict on board guest count to well below our licensed capacity.

We are NOT a cattle-car style tour company!

Ground transportation is included. We pick up guests at the lobbies of all hotels in the greater Cabo and San Jose areas. 

On average, we take out six to eight guests per trip. We are NOT a cattle-car style tour company!
The 96' Pacifica is a large spacious yacht licensed to carry fifty day-time guests, but we restrict guests count to a maximum of twenty for service quality reasons. We restrict overnight guests to a maximum of eight guests.

The sailing catamaran is the largest, and certainly the nicest of the vessels doing this activity, second only to Pacifica. It is licensed to carry 30 guests in open water, but we self-restrict this particular activity to no more than twenty guests as well, and only average six to eight per day. We have lots of space and are virtually never crowded. We provide a chef, meals, beverages, an open bar, a marine biologist as hostess and snorkel leader, certified guides as required with separate snorkel boats, depending on how many persons are on board.
