The "isle of reefs" is considered the best lagoon excursion of all. Located about an hour due south of Avatoru, it's an area dotted with raised feo (coral outcrops), some 16 to 19 feet (5 to 6 meters) above the lagoon. These amazing formations are on the ocean side so you'll have to put on your reef shoes to explore them. They stretch about 300 feet (9 meters) and between them are pools perfect for swimming and excellent snorkeling. Picnics are usually held on one
of the larger motus.
