A friend referred me to this shop as she had taken the Open Water Dive Program with them and…read morethoroughly enjoyed it. She said the instructor made her feel safe and helped her feel confident with her abilities in the water. I couldn't agree more. Steve is an excellent teacher/coach, and just a kind/patient human overall :) . I was deathly afraid of the mask removal underwater and Steve's calm approach helped me get over that fear. This shop truly puts safety as it's number one priority and I'm so glad to have found them. I'm thinking to take my advance class here as well now that I'm addicted to the sport and truly feel confident and safe in my abilities.

California Ocean Adventures is a FANTASTIC dive school and shop!!!…read more I researched a lot of dive schools before choosing this one. I was primarily looking to obtain my open water certification with a school who has a low student to teacher ratio. I also needed a patient instructor, as I was a bit challenged in the Discovery Scuba class I took in Maui. I drove down to Santa Cruz to buy the required mask, snorkel, fins, gloves, and booties for my upcoming certification. Both Brian and Steve suggested gear and gave me options that would meet my individual needs. I was very happy with my purchase. Brian, the instructor and owner exceeded my exceptions. He went above and beyond in so many ways! He was super patient, extremely encouraging, and made my dives very memorable!! Brian sets the class pace and learning to meet the students needs. Not only did we practice the skills needed for the certification, but we spent time on the dive just exploring and having fun! I highly recommend this place for all your scuba needs!!!

Everything met my expectations…read more I wanted to do a 2-tank dive at Point Lobos. I called and scheduled a dive 2 weeks early. The dive shop secured the licenses and permits to dive at Point Lobos, which is a state park. Dive masters are contracted by dive shops so they will have multiple divers diving from their shops. I rented gear from the shop and was assigned Nani as my dive master. The dive shop is conveniently located off the main road and highway. I spent more than usual, because I dove by myself, so I didn't get to split the dive master fees, buts it's all good in 2026, my resolution is to spend more time and experiences, rather than material things... so I finished my dive day experiencing diving in this iconic lagoon, I took lots of GoPro film, and free stickers compliments of the dive shop!

If you want an adventure, you want to know Captain James Moskito and Safari Monterey…read more I've known James for years and have done a few various adventures with him from whale watching to white shark adventures. I haven't been on one of his travel vacations yet, but plan on it one day. He's a class act, extremely knowledgeable about his field, the animals, the adventures, the conservation, the areas, etc etc.; Whatever adventure you decide to take with Safari Monterey, just know it'll be a great time and he'll bust his ass to make sure you get the experience you pay for. That being said, nature is nature and NOT a zoo, so you may or may not see the animal du jour, but just know that it won't be due to lack of effort On James' part. This weekend I did a whale and white shark tour; 3 hours encircled by 20+ Whales and 4 hours searching for Great Whites, all while covering 64-nautical miles and we didn't see a White Shark until 10-min before docking! Luckily, I had my camera out taking a photo of a Pelican, when James yelled "SHARK", then brought the boat to a stop... and that was it. The shark went down and didn't come back up. We estimated at 11'-13'. It was a BIG dorsal fin. There were Whales everywhere you looked all across the bay and we got our fill there. Just came up short on White Sharks, but it was a great day overall with James and Safari Monterey.
