Big Blue’s bar provides a perfect setting for sunset drinks, post-dive socialising, and catching sporting events on the big screen, while daily football and volleyball matches are organised on the beach. Guests are free to relax beside the 12-metre saltwater pool or indulge themselves with a soothing spa treatment at the beach-front massage parlour.

The resort’s partner programme, Big Blue Conservation organises charity events to support community conservation initiatives, such as its annual Swim for Sharks fundraiser. The dive centre’s energetic team regularly leads its own beach clean-ups, coral and species surveys, and artificial reef development. Guests are invited to join in a variety of these activities, as well as marine ecology speciality courses offered by multiple diving organisations.
The resort operates with a general ethos of sustainability, limiting its ecological footprint as much as possible and encouraging sustainable practices among its guests. Its conservation programme urges guests to reduce single-use bags, straws, and bottles, offering sustainable substitutes for all on-site. The resort also supports community projects like facilitating responsible disposal of cigarette butts and upcycling single-use plastic into construction materials.
