Alega (pronounced Alenga) is a small village on Tutuila's south coast, about 10 kilometres east of Pago Pago. The beach here is one of the better snorkeling spots on the island.
The beach is village-owned, and you'll need to get permission from the matai (chief) before using it — look for Tisa's Barefoot Bar at the east end of the beach, where you can arrange access. Tisa's is a well-known local institution, built from salvaged timber and natural materials, and serves drinks in a setting that feels genuinely Pacific.
Snorkeling is best at the edge of the channel that runs through the bay toward open water. There's a rope and buoy to hold — useful, since the current at the channel mouth is strong. The reef drops off sharply and the marine life is rich. Shark sightings (mostly reef sharks at depth) are not uncommon when conditions are clear.
The channel current is genuinely dangerous. Swim only when the sea is calm and stay attached to the rope when at the drop-off. Don't venture into the open channel.
Alega hosts an annual tattoo festival drawing artists from across Polynesia. Like all Samoan villages, it observes Sunday strictly — don't visit on a Sunday without a specific invitation.
