Southwest-coast day-boat diving, guided reef snorkeling and a river-mouth resort base.
Overview
Bentota, Aluthgama and Beruwala join riverfront resorts to seasonal Indian Ocean diving. Local scuba operators advertise introductory training and guided offshore day trips, with the clearest planning case from November to April. Guided snorkeling is separately advertised at Beruwala reefs and on operator-selected Bentota outings; river watersports do not automatically mean safe snorkeling. Non-divers have mangrove cruises, gardens, beaches, temple visits and resort wellness. Offshore access depends on the monsoon, river mouth and each crew's daily decision. No dedicated freedive program or local liveaboard itinerary was verified. Confirm schedules, actual entry site, certification limits and emergency procedures before paying.
Bentota and Beruwala operators market ordinary local dive boats and training rather than overnight dive-liveaboard departures.
LSR and other local listings point to November-April for offshore diving; December-March is the more conservative weather-first plan.
There is direct evidence for guided snorkeling from Malu Banna and near Beruwala Lighthouse, but entry conditions and water quality must be checked for each outing.
