Families with children can take advantage of the Squid Squad Kids Club’s so parents can enjoy some adult exploration time. Savor a tropical buffet lunch onboard the catamaran midday, and recharge with afternoon tea. After approximately 3.5 hours at the reef, relax on the return ride to Port Douglas.  See Itinerary below for a complete description of all included and optional tours and activities.
