How to plan to see and explore them?

• Early start: Visit early morning for better light, fewer crowds, and more comfortable temperatures.
• Guides matter: For many heritage sites (esp. ruins, intangible culture festivals), hire a local guide to give context and depth.

Pack smart:

• Modest clothing for religious/royal sites.
• Sun‑hat, sunscreen, insect repellent for nature sites.
• Good walking shoes (some terrain uneven).
• Camera/phone with extra battery.

Respect & sustainability:

• No graffiti, no picking or damaging natural/cultural features.
• Support local communities — buy from village craftsmen, attend local performances.
• Follow designated paths and boat routes; avoid venturing off‑track into sensitive zones.
• Link travel legs: Many of these sites can be combined in logical geographic routes (e.g., Hanoi → Hạ Long → Ninh Bình; or Da Nẵng → Hoi An → My Sơn → Huế).
• Check local conditions: Weather, festival schedules, opening hours, transport options — all vary by region and season.

Vietnam’s heritage is not just a travel‑add‑on: it is central to the experience.
