Pointe Vénus

Pointe Vénus is on the north coast of Tahiti, at Mahina, about a half-hour drive from Papeete. It is a long black-sand beach on Matavai Bay, with a lighthouse at the point and ironwood trees behind the sand.

The name is astronomical. James Cook anchored here in 1769 on the first of his Pacific voyages, specifically to observe the transit of Venus across the sun — an observation intended to help calculate the distance from the Earth to the sun, made simultaneously from points around the globe. The observation itself was compromised by an optical effect nobody then understood, but the voyage went on to chart New Zealand and the east coast of Australia.

The beach is black volcanic sand, coarse and warm, on a bay protected by reef. It is one of the few substantial public beaches on Tahiti itself — most of the island's shoreline is either rocky, built on, or attached to property — and it is used heavily by Tahitians rather than by visitors, who mostly transit through Tahiti on the way to Moʻorea and Bora Bora. The lighthouse was built in 1867 by the father of Robert Louis Stevenson's engineering family, which built most of Scotland's lighthouses and one here.

Facilities are a car park, snack vans, toilets and shade from the trees. The lighthouse dates from 1867 and a monument marks the observation site. Papenoo and Taharuu further round the coast are the surf beaches, and the black sand runs the length of Tahiti's north and east shores.

Cook anchored here in 1769 to watch Venus cross the sun, the observation was spoiled by an optical effect nobody then understood, and the voyage went on to chart New Zealand and eastern Australia. The beach is black basalt, shaded by ironwood, and used by Tahitians rather than by visitors, who mostly pass through Tahiti on the way to somewhere whiter.
