If it’s your first time, I’d say split it by regions: Hanoi for that chaotic old-town vibe and street food, then Ha Long Bay for the scenery; down south, Ho Chi Minh City feels more modern and busy, plus you’ve got the Mekong Delta nearby. Personally, I really like central Vietnam. Da Nang is chill, Hoi An has that beautiful lantern-lit old town, and Hue gives you a bit of history, so it depends on whether you want culture, nature, or just a relaxed trip.
