Join renowned underwater photographers and REEF Board of Trustees members Ned and Anna DeLoach for an unforgettable Field Survey Trip to one of the best yet least known dive destinations in the world, nestled in the unique, volcanic landscape of North Sulawesi, Indonesia. The 11-day adventure will begin in Lembeh Strait at Eco Divers Lembeh, a macro marine creature-lover’s paradise. On each dive day, your fully-equipped day-liveaboard will moor over shallow, black sandy slopes where a vast array of weird and wonderful fish and critters live.

Ned and Anna’s expert guidance will allow participants to experience a whole new side of muck diving. Participants will then transfer to Eco Divers Manado, for 5 days of diving Bunaken National Park. The waters of the park are home to shoals of red tooth triggerfish, bannerfish and pyramid butterflyfish, as well as reef sharks, turtles, Napoleon wrasse and eagle rays. The resort is situated in an unspoiled and serene location, far from crowds, allowing for a peaceful experience both topside and underwater. REEF’s Indonesia Field Survey offers the chance to examine the unusual, and often undiscovered, marine life found in this unique region of the Central Indo-Pacific.
