Sanya is Hainan’s main beach resort city — the best starting point for first-time visitors who want sand, sea, and easy resort days.
Yalong Bay: best beach quality and upscale resorts. Dadonghai: convenient, lively, good for short stays. Sanya Bay: airport access and value hotels. Haitang Bay: luxury resorts and the large duty-free complex.
Beach time, island day trips (Wuzhizhou / West Island), seafood dinners, and a half-day for duty-free shopping if that is part of your plan.
3–5 nights in Sanya is the sweet spot for most first trips.
Yes in designated beach areas, especially in calmer seasons. Always follow local flags and hotel guidance.
No. You can find value stays in Sanya Bay and Dadonghai, while Yalong and Haitang skew more premium.
