What makes Big Blue Diving Different?

  • With 4 large diving vessels, Big Blue Diving can ensure customers of various levels and disciplines can train at different sites at the same time. 
  • Trips leave directly from Sairee Beach, so there is no need for taxi rides or long climbs over other boats at the pier to reach the dive vessels. 
  • Big Blue Diving is passionate about getting involved in community projects. They have lent their bar and restaurant to many fundraisers and community events over the years, and host the ever-popular Swim for Sharks event every August. 
  • With a broad range of courses and well-qualified staff, Big Blue Diving offers certification through a range of many agencies, including SSI, PADI, BSAC, TDI, and SDI
