This is a fantastic dive site, and when the visibility is good, it can be one of the best dive sites in Bunaken. The word Tengah translates as in the middle as the dive site is found in the middle part of the western side of Bunaken Island. It has a varied topography and a huge number of marine species and so makes for a great dive. It is no surprise that it is one of the most popular sites in the area.
The dive site is made up of a vertical wall that provides a highly variable dive site. The plateau of the wall is found at around 5 to 10 metres and then the site slopes down to a wall that drops below 50 metres. Visibility can be poor here and be lower than 10 metres but on good days, it can extend to 35 metres. There is a good level of current but in between the tides, it is relatively calm. The current helps to make this site a great drift dive.
Divers will be able to see a large variety of marine life of all shapes and sizes. The wall is covered with corals both soft and hard and has many crevices, small holes, and nooks and crannies that house macro critters including many different types of nudibranchs. The wall is covered in schooling fish such as parrotfish, batfish, and fusiliers. There are also stingrays, eagle rays, mobula rays, black tip reef sharks, and white tip reef sharks to be spotted. Divers should also check underneath some of the corals for juvenile sharks that often congregate here.
