Dhigali Haa

Dhigali Haa stands as one of the Maldives’ most significant Marine Protected Areas, designated by the Government of Maldives on October 21, 1999. Also known as Horubadhoo Thila, this 125-hectare protected pinnacle lies southwest of Royal Island Resort and Spa in Baa Atoll. As part of the UNESCO Baa Atoll Biosphere Reserve since 2011, Dhigali Haa represents the commitment to preserving the remarkable marine biodiversity of this globally significant region.

The Dive

The pinnacle rises from the sandy bottom with its reef top beginning at 8-16 metres, descending to depths of 30-40 metres. This long, narrow reef structure features a small canyon on the west side and another on the north, both reaching approximately 20 metres. Throughout the dive, you’ll discover passageways created by coral blocks that have separated from the main reef, along with overhangs draped in soft corals and anemones. The northern tip and western side are adorned with impressive black coral trees. The circular nature of the reef allows divers to explore the entire structure in a single dive.

Marine Life

Dhigali Haa boasts spectacular fish life throughout its protected waters. Schools of Big-Eyed Jacks hunt around the reef while Grey Reef Sharks patrol the blue and elegant Eagle Rays glide through the currents. One of the site’s most charming encounters comes from the curious Batfish that often follow divers, playfully interacting with their exhaled bubbles. The overhangs shelter Tawny Nurse Sharks resting during the day, and the beautiful garden of Sea Anemones hosts endemic Maldive Anemonefish alongside Clark’s Anemonefish. During the southwest monsoon season from May to November, Manta Rays visit the cleaning station on the reef. Hawksbill Turtles are frequently spotted, and Napoleon Wrasse cruise through the area with their distinctive presence.

Conservation

As one of the Maldives’ officially designated Marine Protected Areas since October 1999, Dhigali Haa benefits from strict conservation measures that have allowed its ecosystem to flourish. The 125-hectare protected zone became part of the UNESCO Baa Atoll Biosphere Reserve in 2011, recognising the area’s exceptional biodiversity value. Scientific studies conducted here between 1999 and 2001 documented remarkable coral resilience, with juvenile Acropora corals showing an 18-fold increase in surface area. This site represents one of the world’s eleven marine biodiversity hotspots and continues to serve as a benchmark for coral research. Visitors are encouraged to practice responsible diving to help preserve this precious marine sanctuary for future generations.

Conditions

Visibility at Dhigali Haa typically ranges from 10-30 metres, with the best conditions during the Northwest Monsoon season. Currents are generally medium at 1-2 knots but can be variable, requiring good buoyancy control. Water temperatures remain warm year-round between 28-30°C. Due to the depth profile and variable currents, Advanced certification is recommended. The site is accessible only by boat, approximately 20 minutes from Maalhos Island.
