Samoa offers visitors the chance to experience Polynesia at its most authentic. The capital, Apia, lies on the beautiful north coast of Upolu, the largest and most populous of the country's nine islands.
In the Aleipata district, waterfalls and white-sand beaches dominate the landscape. A 65km (40 mile) drive from Apia leads to the Falefa Falls, Mafa Pass and the Fuipisia Falls.
