“Amazing Diving– great operation”

This was my first visit to St. Maarten and we dove with Octopus out of Bobby’s Marina. We did 3 days and I was able to finish my Advanced Open Water cert thanks to my instructor Evelien and Captain Willem– they were outstanding! Very helpful, fun, thorough, safe and friendly. They took us to tremendous dive sites and we saw sharks, rays, turtles, eels, huge lobsters in a wreck. Really great experience and I would highly recommend them! Owner Sally was very helpful in accommodating our group and getting my course dives arranged. Will definitely dive with them again and I would recommend them highly!

“Highly regarded Dive Operation and Great Snorkeling Experiences!”

Octopus Diving is located in Grand Case on the French side of the island and offers Dive Tours, Dive Courses (PADI) and Snorkeling Tours, in addition to charters. Quality equipment is provided for both diving & snorkeling and their fleet of boats (see their website) is well maintained & designed for these purposes. The staff are well trained & professional (with an added bit of humour). Our trip was a half day visit to 2 sites, with a combination of divers & snorkelers & all was well organized and went very smoothly. Captain Ian & Divemaster Mike did an excellent job, with this being my 2nd year for an excursion with Octopus. If you want the best, don’t look any farther.

“Fantastic Operation!”

My wife and I recently had the pleasure of diving with Octopus Diving in Grand Case, St Maarten. Definitely one of the best operaters we’ve had the pleasure of going out with. Great boats, safe operation and processes, friendly and helpful dive masters, and convenient location. Basically – Octopus Diving is everything a quality dive operator should be…and more. I would definitely recommend them if you’re on the island and looking to do some diving. Oh yeah…and on the first dive – we saw 3 dolphins. Nice bonus.
