• See the House of Taga. Stand beside the massive latte stones of an ancient Chamorro chief on Tinian.
• Swim at Rota's Swimming Hole. Float in a natural ocean pool sheltered by rocks in Rota's Song Song village.
• Explore Tinian's North Field. Walk the historic runways and atomic bomb loading pits of the Second World War.
• Watch the sunset at Bird Island. Look out over a striking limestone islet that shelters seabirds off Saipan's north-east coast.
