The window for close encounters with the region's famed filter‑feeders stretches from November to June, but the subtle differences within that span matter. Early‑season visitors (November‑January) often find the waters teeming with juvenile sharks that linger near the surface, making for calmer swims and clearer sightings. By March‑April, the larger, more seasoned individuals dominate the bays, and currents can be stronger, demanding a steadier boat and a more experienced guide. Late‑season (May‑June) offers a quieter atmosphere as the month‑long peak wanes, yet the light is softer and the surrounding mangroves are at their freshest, creating a more reflective backdrop for photography. Planning around these nuances lets travellers align their expectations with the marine choreography rather than merely showing up during the broad “season.”
While the oceanic spectacle draws most, Donsol’s modest town centre rewards a short stroll with a glimpse of Bicolano resilience. The weekly market, held every Saturday, showcases a kaleidoscope of tropical fruits—sapa, lanzones, and the fiery chilies that define the region’s cuisine. Tasting a steaming bowl of laing, a local dish of taro leaves simmered in coconut milk and pork, offers a palate‑warming counterpoint to the cool sea. For a lingering afternoon, visit the nearby Sorsogon Provincial Museum’s satellite exhibit, which presents artefacts from the town’s 17th‑century founding, linking the modern tourism boom to its colonial roots. These low‑key experiences enrich the marine adventure with a sense of place.
The surge in marine tourism has prompted local operators to adopt a code of conduct aimed at preserving the sharks’ natural behaviour. Newcomers should bring reef‑safe sunscreen, avoid flash photography, and maintain a respectful distance of at least three metres. Several dive shops now offer brief orientation sessions that explain the sharks’ feeding patterns and why sudden movements can cause stress. Participating in a community‑run beach clean‑up—often organised on the same day as the morning swims—helps offset the environmental footprint of a day’s travel. By adhering to these modest guidelines, visitors contribute to a model where the attraction remains viable for future cohorts, turning a simple excursion into an act of stewardship.

(February 2013) (Learn how and when to remove this message) Whale shark viewing[edit] Butanding whale shark in Donsol, Sorsogon Swimming with whale sharks, locally known as butanding, was featured as the Best Animal Encounter in Asia by Time magazine in 2004. Whale sharks can be seen between November and June, with presence peaking between February and May. For over a century, Donsol residents believed whale sharks were dangerous. These gentle giants, *Rhincodon typus*, were misunderstood until December 26, 1997, when diving instructor Romir Aglugub and his group encountered them peacefully while scuba diving. At first, Aglugub's fellow divers doubted the gentle nature of whale sharks. However, after swimming with them, they observed their calm behavior. Their experience, documented on video and shared with the media and WWF-Philippines, helped dispel myths and initiated scientific research in Donsol. By 1998, whale sharks became symbols of Donsol’s natural heritage and earned it the title “Whale Shark Capital of the World.” This shift spurred eco-tourism and highlighted the value of education in marine conservation, thanks to Aglugub's efforts. Interaction with the whale sharks is regulated by the local Department of Tourism (DOT) office. WWF guidelines are generally observed to protect the sharks. Rules include limiting the number of swimmers per boat to six, prohibiting scuba divers, and requiring staying farther than three meters from the sharks. In recent years the number of male sharks has out-numbered female sharks by 20:1. Generally, the females that are seen are large mature adults in the 7m ~ 9m range. Increasing numbers of sharks show propeller marks on their backs. Anecdotal evidence from local fishermen suggests that prop strikes are from fishing boats in the off-season, rather than from tourist boats during the main February–June tourist season. In 2006 five sharks were found dead on the surface of the water, within 30 miles of Donsol. They had all been shot at close range. One shark had 13 bullet wounds to the head. The locals blame this on commercial fishermen shooting the sharks if they are caught in their nets. Manta rays, which are also protected in the Philippines, are also over-fished and sold in local markets in the Sorsogon area. Groups from Singapore, Hong Kong, Taiwan, and the Philippines make up the largest groups of visitors. Most tourists book guided tours with dive centers familiar with whale shark interaction. Other attractions[edit] Donsol has a night firefly tour and shrimp-catching night tour available all-year round. Donsol also is becoming the best jump-off and base for divers to the Manta Bowl and San Miguel Island in Ticao due to the existence of better tourist facilities. Diving in Donsol itself is not allowed. Donsol also is a trekking and biking site, due mainly to the abundance of hilly areas and fields.
