Going beyond recreational limits can be, in almost every occassion, incredibly thrilling. The depths of the Sea of Cortez remain always unspoilt and unexplored and very often will reward us with unexpected landscapes and life forms. From solitary sharks amd thick black coral forests to deep walls and formidable pinnacles. Technical diving in Baja is barely developed, but counts with a small but dedicated community that is determined to bring you the best that the Cortez has to offer.

Ask us!

There are several good spots for technical divers around the three main islands of the Loreto Bay National Park.

There are deep walls and pinnacles, black coral forests and deep seamounts among other attractions. Many dives can be enjoyed within recreational depth limits but for an extended bottom time. The underwater scenery gets incredibly variated here, making long and deep drift dives totally worthwhile.

Deco shouldn’t be boring neither! The shallows offer an unmatched life diversity and plenty of shelter for an effective decompression.

The trip also includes a short tour around the Park where we can stop and relax with some snacks after the dive, or even do some snorkeling.

*Please note that tech dives must be booked with at least 48 hours in advance.
