About Maribojoc Bay
Maribojoc Bay, situated on the southwestern coast of Bohol, Philippines, is renowned for its significant seagrass beds rather than traditional coral reefs. The bay was historically known as "Dunggoan," meaning "place of anchorage," due to its sheltered waters. This area is a crucial ecological zone, supporting various marine organisms that thrive within its meadows. The municipality of Maribojoc officially became a town in 1860 and holds a rich history, serving as a mother parish for nearby towns like Cortes and Antequera. Ecological studies in Maribojoc Bay, conducted from October to December, have identified seven species of seagrass, with Thalassia hemprichii being the most prevalent. While the overall diversity of seagrass species is considered low, these meadows are characterized by patchy and continuous coverage, ranging from poor to good conditions, with an average of 38.65% coverage. This environment makes it a distinctive site for divers interested in different types of marine ecosystems. While not a typical coral-dominated dive site, the seagrass meadows serve as critical nurseries and foraging grounds, attracting a specific array of marine fauna. Divers can anticipate encountering various small invertebrates, juveniles of reef fish, and other specialized species adapted to this unique habitat. The protected nature of the bay and the relatively shallow depths make it accessible for divers looking for a more relaxed and observational dive experience. The dive experience here focuses on exploring the intricacies of the seagrass community. Expect longer bottom times at shallower depths, allowing for detailed observation of macro-life. The conditions generally support comfortable diving, though specific current information is essential for planning. Maribojoc Bay offers a different perspective on marine biodiversity, highlighting the importance of seagrass ecosystems.

Conditions & Currents
Maribojoc Bay is typically sheltered, suggesting generally mild current conditions suitable for leisurely exploration of its seagrass beds. However, like any coastal area, local tidal movements can influence water flow, particularly near channel entrances or during significant tide changes. Divers should always consult with local guides for real-time current assessments, especially for specific dive spots within the bay. Visibility can be affected by sediment disturbance within the seagrass or runoff from the nearby land, so clarity may vary. The bay's sheltered nature generally provides a calm entry and exit point, but maintaining good buoyancy control is crucial to avoid damaging the delicate seagrass ecosystem and stirring up the bottom.

A typical dive in Maribojoc Bay begins with a gentle descent into the seagrass meadows, usually from a boat. The dive plan focuses on exploring the diverse life within these shallower ecosystems, often staying between 5-15 meters to maximize observation time. Divers will navigate slowly over and through the seagrass, looking for macro subjects hiding amongst the blades. The route generally follows a gentle contour, allowing for gradual depth changes. Turn points are typically dictated by air consumption or bottom time, ensuring a safe return to the ascent point. Safety stops are performed in the shallow, protected waters of the bay, providing an opportunity for a final look at the juvenile marine life often found near the surface.
Underwater photography
Maribojoc Bay is a prime location for macro photography, given its rich seagrass beds that host a variety of small, camouflaged creatures. A macro lens is essential to capture the intricate details of tiny invertebrates, juvenile fish, and unique critters that blend into the environment. Consider using a snoot with your strobes to highlight subjects against the green backdrop and minimize backscatter from any suspended particles. Good buoyancy control is paramount here to avoid disturbing the seagrass and stirring up the sediment, which can quickly reduce visibility. Patience is key, as many subjects are well-hidden, requiring careful observation.

Getting there & logistics
Access to Maribojoc Bay is typically through Tagbilaran City on Bohol. The Bohol-Panglao International Airport (BPIA) serves as the main gateway, with regular flights from major Philippine cities like Manila and Cebu. From the airport, it's a short drive to Maribojoc or other popular dive centers on Panglao Island, which often arrange day trips to the bay. Most dive operators on Bohol can facilitate dives in Maribojoc Bay, often combining it with other local sites as part of a multi-day dive package. There are no specific marine park fees mentioned for Maribojoc Bay itself, but it's advisable to confirm with your dive operator.
Safety & environment
While Maribojoc Bay is generally considered safe for diving due to its sheltered nature, standard diving safety protocols are crucial. Always dive with a reputable operator and ensure your equipment is well-maintained. The nearest recompression chamber is located in Cebu City, necessitating a boat transfer followed by land travel in case of a serious diving emergency. Therefore, comprehensive dive insurance is highly recommended. Divers should practice excellent buoyancy control to avoid damaging the fragile seagrass beds or stirring up sediment, which can reduce visibility and impact the ecosystem. Always follow your dive guide's instructions and be mindful of marine life.

Why dive Maribojoc Bay from a liveaboard?
Maribojoc Bay is one of Philippines's signature dive sites. A liveaboard sleeps you on the water and puts you in the water for three to four guided dives per day, including dawn and night dives that day-boat operators rarely offer. You skip the daily commute back to port and reach quieter, less-crowded sites in the same region on a single trip.
