Ofu Beach Walk

This is less a hike and more a pilgrimage to one of the most stunning beaches in the entire National Park system — and hardly anyone knows it exists. You'll walk along Ofu's south shore, where powdery white sand meets water so clear it looks photoshopped. The trail is dead flat, hugging the coastline with barely enough elevation change to qualify as a speed bump. The real attraction is what's just offshore: a coral reef ecosystem that marine biologists have called one of the healthiest on Earth, with brain corals the size of small cars and fish so abundant they bump into your mask. The sand can get scorching underfoot at midday, and coconut palms offer occasional shade but not much. This is paradise for snorkelers, beachcombers, and anyone who wants to feel like they've reached the edge of the map.
