Today’s the one where it all properly begins. Grab breakfast on the go, throw on something beach-ready and get set for your first real taste of island life. First stop: the marina. Think cafes, shops and polished harbour views as you board the ferry. Then it’s out onto open water, cruising towards the Mamanuca Islands with nothing but blue in every direction. We'll touch down and step straight into beach club mode. Spend the morning swimming, snorkelling or drifting between the infinity pool and the sea. In the afternoon, a local marine biologist will give us the lowdown on reef conservation before your chance to try out your snorkelling skills in the water. The rest of the time is yours—food, drinks and extras on hand if you like. Next, we'll transfer across to South Sea Island and settle in for our overnight stay. Spend the the rest of the day however you like—kayak, paddleboard, snorkel or jump on the glass-bottom boat to see what’s beneath the surface. And once the day visitors head off, and the island becomes your space—just our Contiki crew and the ocean all around. Dinner’s on us, as we wrap up the evening with a fire dance performance.
