The Ninh Binh Trang An tour, boasting the best natural scenery near Hanoi, is a healing course where you ride a sampan through caves amidst towering limestone cliffs. It's usually recommended as a day trip, combined with Hoa Lu and Hang Mua viewpoint. For 2-3 hours, a boatman rows you through caves and temples, offering a fantastic landscape that truly earns its nickname, 'Ha Long Bay on land.' There are three Trang An boat tour routes, with the one passing through many caves (usually route 2 or 3) being the most popular. A tip: it's good to give a tip (around $2-$4) to the boatman as a token of appreciation. Tour participation on March 14, 2026. The weather was cool and excellent. Guide Mr. Victor, you did a great job during the tour. Thank you.
