Tutuila is the largest of American Samoa's seven islands and the main base for travelers. Nearly all flights arrive here, and Pago Pago — the capital — is on Tutuila's south coast, inside the deep harbor carved by a collapsed volcanic caldera.
The National Park of American Samoa covers a significant portion of the island's northern coast, protecting one of the last intact tropical rainforests in the American territories. Start at the visitor centre in Fagatogo before heading out. A scenic road runs from Pago Pago over to the north coast — allow a few hours, including stops at the viewpoints along Afono Pass. The Amalau Valley is one of the better spots to watch for flying foxes gliding above the canopy.
From the village of Vatia on the north coast, a trail leads toward the sea cliffs overlooking Pola Island. It's a short walk with dramatic views.
The Mount 'Alava trail follows a maintenance road to a 491-metre summit with panoramic views over the harbour and north coast. The trailhead is at Fagasa Pass, a short drive from town. For history, the Jean P. Haydon Museum in Fagatogo covers Samoan culture and the naval period, and Massacre Bay on the northwest coast marks the site of a deadly 1787 encounter between French explorers and local islanders.
