Tuần Châu Island
"We crossed a two-kilometer bridge to reach an island that felt like a departure lounge for another world."
A causeway-linked island where prehistoric settlers once lived, now the bustling harbor gateway to Hạ Long Bay's limestone karsts.
Lia and I almost didn’t stop on Tuần Châu Island at all. We’d booked an overnight cruise out of Hạ Long City and figured the island was just a logistical footnote, a place to park the car before boarding. But the causeway ride out there — a straight two-kilometer stretch of road with water on both sides — already set a different mood than the mainland traffic we’d left behind. It’s one of the few islands in the whole bay you can actually drive onto, and that alone makes it feel like a hinge point between ordinary life and the bay’s dreamlike stillness.
What surprised me most was learning that people lived on this small, roughly 2.2-square-kilometer patch of land thousands of years before anyone thought to build a harbor here. Archaeologists have traced human presence back 3,000 to 5,000 years, and later the island did a stint as a military outpost during Vietnam’s long wars. Standing at the edge of the modern marina, watching wooden junk boats queue up for departure, it was strange to think how much history had passed through this quiet spit of land before it became the launchpad for tourists like us.
We had a couple of hours to kill before boarding, so we wandered the artificial beach that’s sprung up alongside the resort development of the last two decades or so. It’s not wild or rugged — the sand was clearly trucked in, and there were beach chairs and a snack stand — but Lia loved wading in while I ate a plate of grilled squid from a stall near the pier, watching boat crews load coolers and diesel cans for the trip out. There’s a slightly surreal contrast on Tuần Châu: manicured resort landscaping on one side, and just past the marina wall, those jagged karst silhouettes rising out of the water like something from another geological age entirely.
By the time our boat’s horn sounded, I understood why nearly every cruise in Hạ Long Bay starts here. Tuần Châu isn’t the postcard moment — it’s the threshold you cross to get to it, and there’s something fitting about a place shaped by so many centuries of people arriving, staying briefly, and moving on toward the water.
When to go: We went in November, and the sky was that crisp, pale blue you rarely get in the bay’s hazier summer months — perfect for photos of the karsts before we even left the harbor. Aim for October through December if you want cooler air and clear visibility right as you board.
