Rose Atoll

Rose Atoll, sometimes called Rose Island or Motu O Manu ("Bird Island") by people of the Manu'a Islands, is an oceanic atoll within the U.S. territory of American Samoa. An uninhabited wildlife refuge, it is the southernmost point belonging to the United States, about 170 miles (150 nmi; 270 km) to the east of Tutuila, the principal island of American Samoa. The land area is just 0.05 km2 (12 acres) at high tide.

The total area of the atoll, including lagoon and reef flat amounts to 6.33 km2 (1,560 acres). Just west of the northernmost point is a channel into the lagoon, about 80 metres (260 ft) wide. There are two islets on the northeastern rim of the reef, larger Rose Island, 3.5 metres (11 ft) high, in the east and the non-vegetated Sand Island, 1.5 metres (5 ft) high, in the north.

The Rose Atoll Marine National Monument that lies on the two outstanding islands of the atoll is managed cooperatively between the U.S. Fish and Wildlife Service and the government of American Samoa. The nearly square atoll is one of the smallest in the world, measuring only 2.6 km × 2.7 km (1.6 mi × 1.7 mi).

Rose Atoll occupies a particular place in the imagination of American public lands. As a Park Unit in its home region, it represents a deliberate choice — by the people who advocated for its protection, and by the National Park Service rangers who maintain it — to keep this landscape available to anyone willing to make the trip. That accessibility is the quiet miracle of the park system.

The pages linked below break the visit down into the four practical questions every traveler asks: where can I hike, where can I sleep, what else is worth seeing while I'm in the area, and what should I know before I show up. Each one is written from the perspective of someone planning their first trip — assume nothing, explain what's worth explaining, and skip the marketing language. If you've been here before, treat these guides as a refresher and a way to discover the corners you missed last time.
