Hi!. After 20 years diving as professional I only could say Lumba Lumba in Palau Weh, is the worse and the most dangerous place I've ever seen. In last 2 months, 6 people where to hospital. When I been there, the second day I felt strong headache. I inspect the tanks, and all of them where out of service, then when you dive there, you get air intoxication. The equipment for rent is completely out of service. A disaster. Go diving Palau Whe, is really nice place, but not in Lumba-Lumba.
