The Shangri-La Marine Sanctuary spans five hectares from the beachfront of the resort. It was formally established by the Lapu-Lapu City Council, filing it under the Lapu-Lapu City Ordinance 425-B-2006, on 26 November 2006.

The Shangri-La Marine Sanctuary Stewardship Group, composed of the resort, Scotty’s Action Sports Network, and Amores Charities, Inc., shares the responsibility of protecting the fragile coral reefs of Mactan, Cebu.

Furthermore, the hotel management and staff participate in coral recovery programmes and monthly beach cleanups.
