Kê Gà Lighthouse stands on a small granite islet a few hundred metres off the Bình Thuận coast. The waters here were once notorious for dangerous underwater reefs that wrecked or damaged many passing ships, prompting French colonial authorities to survey the area and build a lighthouse to guide vessels safely through - designed by French engineer Chnavat, construction began in February 1897, and the lighthouse became operational in 1899.
Vietnam's Oldest Standing Lighthouse
At over 125 years old it is the oldest standing lighthouse in Vietnam, and - at 35 metres tall (65 metres above sea level, roughly equivalent to a 12-storey building) - it's also recognised as the country's tallest. The French-era granite tower, built without mortar from interlocking carved blocks shipped over from France, sits in marked contrast to the granite boulders and scrub vegetation of the islet around it.
Climbing the Tower
Climbing the roughly 183 spiral steps to the top has traditionally been free and open to visitors - the interior is narrow (under 3 metres across, narrowing further near the top), so a little dizziness isn't unusual - taking in the view through small windows along the way before reaching a 360-degree lookout at the summit. Access to the top isn't always guaranteed, though: heritage preservation rules and border-security oversight mean it can sometimes require permission from the border guard post or lighthouse station on the day, so treat the climb as likely but not certain.
The Islet
The lighthouse is reached by a short boat crossing from the mainland beach at Tân Thành, making it one of the more accessible island landmarks on the south-central coast; in March, when the tide runs unusually low, it's sometimes possible to walk across the exposed reef to the island without a boat at all, a distinctive and little-known way to make the crossing.
The surrounding water is clear enough for snorkeling and the islet itself is walkable in 20 minutes - the combination of colonial architecture, coastal scenery, and the short boat adventure makes Kê Gà a compact but rewarding stop.
