I had the chance to dive with Rich Coast Diving in Playas del Coco on both their 2-tank local dive trip and the Bull Shark Diving excursion to the Bat Islands, and both experiences were fantastic.
The local dives were packed with marine life. We saw eels, rays, sharks, sea turtles, and plenty more. The sites were beautiful, the water was full of activity, and the entire day was extremely well organized.
The Bat Islands trip was on another level. Diving with bull sharks in their natural environment was an unforgettable, bucket-list experience. As a PADI Divemaster with more than 100 dives, I can say this was easily one of the most memorable dives I have ever done. Seeing these huge bull sharks underwater, up close and completely in the wild, was absolutely incredible.
The Rich Coast Diving team was professional, knowledgeable, friendly, and very safety-conscious. The briefings were excellent, the crew clearly knew the dive sites, and everything ran smoothly from start to finish.
If you are diving in Costa Rica, do not skip Rich Coast Diving. I highly recommend doing the local dives and, if you are qualified and comfortable with more advanced diving, absolutely make the trip to the Bat Islands.
Five stars all the way. I would dive with them again without hesitation.
