Once at the reef, visitors can participate in snorkeling or diving activities, depending on their experience level and qualifications. The Silversonic tour offers guided snorkeling tours led by experienced instructors and certified diving for those with a diving certification.

No prior scuba diving experience is required for an Introductory Dive (also known as a  “Resort Dive”).    Experience the thrill of scuba diving under the watchful supervision of a professional dive instructor.

Starting with a dive briefing, followed by a step-by-step procedure, guarantees your dive is comfortable and enjoyable.
