Haikou is Hainan’s capital and main northern gateway — useful for flights, culture, local food, and Free Trade Port shopping energy.
City walks, Qilou historic streets, local snacks, evening waterfront vibes, and connecting onward around the island.
Spend 1–2 nights if you arrive or leave via Haikou. Pair it with Sanya rather than treating it as the only stop on a short beach holiday.
Duty-free options and major malls sit near key transport links. High-speed rail makes Haikou–Sanya transfers straightforward.
Usually no. For beach-first trips, base in Sanya and use Haikou as gateway or contrast city.
