It's then covered with a layer of leaves and steamed until ready to enjoy. Savour the earth-oven flavours as ancient stories are shared while traditional dancers and musicians perform before torchlight.

    Discover a Muri Lagoon Motu

    If you go to popular Muri Beach you're sure to notice the picturesque islands offshore. A great way to visit one of these islets, or "motu", is on a glass-bottom boat tour.

You'll disembark on tiny Motu Koromiri, where you can stroll its secluded white sands and enjoy a lunch of barbecued fish right on the beach.
