Make some waves

This place has helped my sons go from barely swimming to serious swimmers. So grateful for their strategic approach and great teachers!

— Kristin G.

The staff at DiVentures is great and really takes time to teach each child in ways that benefit them and their capabilities! My 2 1/2 year old is always comfortable with them.  

— Terra P.

My kiddos love this place! I just wanted to mention how much it meant to me that your dedicated instructors took the extra time to make my youngest comfortable with going into the water. On the way home she told me she loves her new water friends.

Raja Ampat, Indonesia

The only way to visit all of the fantastic reefs in the large Raja Ampat region is by a liveaboard like the luxurious Aurora. The archipelago includes over 1,500 small isles, cays and shoals surrounding four main islands Misool, Salawati, Batanta and Waigeo. The area is a labyrinth of straits between small sandstone islands eroded by waves. The marine life diversity is considerably greater than all other areas sampled in the coral triangle. The moderate currents bring nutrients which means lots of healthy fish and coral. You can expect to see enormous schools of fish, sharks like wobbegongs, large groups of manta rays and turtles, pygmy seahorse, and possibly even get to snorkel with dolphins or passing whales. Advanced Open Water certification is recommended for this trip... Details


The Galapagos Islands are among the most geographically remote on earth. They are truly pristine and one of the very few geographic locations on Earth that remains untouched by man. Fifteen main islands and countless smaller ones dot the archipelago. Three major ocean currents provide the resident marine life with a constant source of nutrients and contributes to amazing biodiversity from big animals to small invertebrates. Galapagos is unquestionably the hammerhead shark capital of the world – but also home to the sleek Galapagos shark, horn sharks, white tips, silkies, and an occasional apex visitor like the tiger shark. Add whale sharks, giant manta rays, and graceful rays of many descriptions, throw in some giant schools of fish, incredible macro marine life, and now you realize just how exciting Galapagos diving can be. You’ll appreciate Trip Leader Pat Purkhiser’s extensive diving knowledge and experience. A marine biology educator and conservation advocate, Pat’s background is a real benefit to this trip.

Guadalupe Island

Join Trip Leaders Chad and Janna Binder for an exciting trip focused great white shark encounters. This small volcanic island, located 150 miles off the west coast of Mexico’s Baja California peninsula, boasts shark viewing in beautiful clear blue water with 100–150-foot visibility. There are 242 unique great white sharks in the bay, which guarantees unforgettable encounters. We offer a rich and natural shark encounter experience on these trips by descending down to 30 feet where great white sharks naturally spend their time. We don’t need to use chum at depth; the sharks are already there. We have seen up to nine great whites at once circling the cages. Without chum these great whites are more relaxed, exhibit much more curiosity, and come in much closer to the cages. It is an unforgettable rush when a great white looks at you from 50 feet away and then swims over for a closer look. We see great whites on three out of four dives... Details

Open Water Certification Course/Instructors
We took our course the beginning of July over a weekend and felt the course was well led. The instructors never made us feel rushed or under pressure, and the skills were taught at a very comfortable pace.

— Mark W.

Great facility, staff and training
My family all recently took training for our open water diving at DiVentures. The staff, instructors, sales, everyone has been so helpful and does a great job. Training is outstanding.

— James K.

What a great experience
I went to their shop being very much a novice to the scuba experience. The staff was very knowledgeable and courteous. They had me take an introduction class, and it blew me away. While I was waiting, I decided to ask the other people their impression of DiVentures, and everyone could not have been more praising.
