Haikou or Sanya?
They are different trips. Sanya is the resort strip; Haikou is the island's lived-in capital — cheaper, quieter, and the better place to eat and understand Hainan. Most travelers do both: Haikou for a day or two, then the 90-minute train south.
How does the 59-nation visa-free actually work?
Fly directly into any Hainan port with an ordinary passport from one of the 59 countries, and you get 30 days for tourism, business, family visits, medical care, expos or sports — no consulate visit. The two catches: entry must be direct into Hainan, and you cannot continue to the mainland on it.
Is the volcano worth half a day?
Yes if you like your geology walkable — it is the rare volcanic field you can circle on a crater rim within city limits. Go early (it bakes by noon), bring water, and expect steps rather than wilderness.
How does duty-free shopping work for foreign visitors?
Duty-free prices apply when you are departing the island: shop with your passport and a confirmed departure ticket, and collect or carry per the store's rules. Buy on your last day — the discount exists because the goods leave Hainan with you.
What should I eat first?
A teahouse breakfast: 海南粉, pineapple buns and a pot of tea at a 老爸茶 house — it is the fastest way into the city's rhythm. Then Wenchang chicken for lunch and qingbuliang whenever the heat wins.
Two days enough?
For the city, yes: old town and museum on day one, volcano and coast on day two, duty-free on the way out. Add a third if you want the beach to be the point rather than the backdrop — or if a typhoon steals a day.
When is typhoon season?
The risk window is roughly July to October, peaking in August–September. Outside it, Haikou is an easy year-round destination — November to April is the dry, gentle season northerners migrate for.
