Dixon’s Pinnacle, Havelock: Diving the Andaman Sea's Pinpoint Reefs

Dixon's Pinnacle is defined by three prominent underwater rock formations, often referred to as Havelock's 'holy trinity' for divers. These pinnacles ascend from deeper waters, creating a unique topography for marine life to congregate. The dive profile typically begins at the uppermost sections, with the first pinnacle starting around 18 metres, the second at 22 to 23 metres, and the third similarly at 23 metres. As you descend along their slopes, you will find the vibrant yellow soft corals that blanket these structures, forming a dense and colourful environment.

The depth range across Dixon's Pinnacle extends from a minimum of 16 metres to a maximum of 35 metres, allowing for varied exploration depending on your certification and gas planning. Each pinnacle gradually slopes down, offering different ecosystems at various depths. Between 20 and 35 metres, the sheer density of coral growth is striking, creating a kaleidoscope of colour, particularly the predominant yellow soft corals which are a hallmark of this site. This provides ample hiding spots and feeding grounds for a variety of reef fish.

Life here is abundant and active. Clouds of orange anthias perpetually curtain the coral structures, a shimmering backdrop to the larger inhabitants. Barracudas, napoleons, and trevally are common sights, often observed cruising the perimeters. Look into the schooling bannerfish and red-toothed triggerfish that navigate around the pinnacles, while moray eels discreetly occupy the crevices within the coral. The first pinnacle's base is a reliable spot to find five-lined snappers congregating.

The site also acts as a cleaning station, particularly for giant groupers, giving divers an opportunity to observe this intricate behaviour up close. Pelagic encounters are a significant draw, with opportunities for sightings of manta rays (Mobula birostris) and various reef sharks. The strong currents that can define the site also contribute to drawing in these larger species, making each dive distinct and unpredictable.

While Dixon's Pinnacle is rich in resident reef fauna, it is also on the migratory path for larger ocean-going species. During the season from November to May, manta rays are frequently sighted, gliding gracefully over the pinnacles. Whale sharks (Rhincodon typus) are seasonal visitors, adding an element of rare excitement to dives during these months, moving through the stronger water movements that sweep across the site.
