Twenty kilometres from Nadi, the coral cays give way to four large volcanic islands making up the Malolo Group. This is the heart of the Mamanucas tourism experience, boasting the most popular and busiest resorts. Malolo, the largest island in the group at just over 2400 acres, and its little sister Malolo Lailai have a scattering of resorts, a marina and the chiefly village of Yaro. Along with beautiful Castaway Island these islands form a cluster protected to the south by the stunning Malolo Barrier Reef. Surfing in the passages is a fifteen-minute boat ride away and advanced scuba divers will enjoy the challenging wall dives on the outer edges of the reef. Six kilometres to the northwest of Malolo is Mana, the liveliest island for backpackers, with lovely beaches to explore.
