Yalong Bay
The 'best bay under heaven' and the most polished stretch of sand in China — clear water, crescent beach and a wall of international resorts. The underwater world and butterfly valley sit at the back of the beach.

Sanya Tours & Travel Guide 2026 | Hainan Beaches, Yalong Bay | JoyoTour
Sanya is Hainan's southern resort coast — Yalong Bay, Haitang Bay, the island of Wuzhizhou and the 108 m sea Guanyin at Nanshan. Private Sanya tours from US$169 a day.
The short version
Sanya is China's tropical beach capital, on the southern tip of Hainan island, and the only place in the country with genuinely warm sea and sun in the winter. Give it 4 days: one for Yalong Bay, one for Wuzhizhou Island, one for Nanshan and Tianya Haijiao, and one for the rainforest or a hot spring. The high season runs November to April; summer is hotter, cheaper and quieter.
- Four days covers the bays, the islands and the Nanshan Buddha comfortably.
- Yalong Bay, Haitang Bay, Dadonghai and Sanya Bay are four different holidays — pick your base deliberately.
- Wuzhizhou Island's ferry and landing fee (about ¥168) is capped by boat, so go early.
- Book before November: winter is peak, and hotel prices double.
- Seafood is bought by weight at the market and cooked to order — learn the system before you sit down.
The place itself
What Sanya is actually like
Sanya sits at 18° north — the same latitude as Hawaii — on the southern coast of Hainan, and the climate does the talking. Average temperatures hover around 25°C, the coldest month still averages 21°C, and there is no winter worth the name. That is why the Chinese call it the 'Oriental Hawaii', and why it fills up the moment the mainland turns cold.
The city is really a string of bays. Yalong Bay, in the south-east, is the polished resort strip with the clearest water and the big international hotels. Haitang Bay, further east, is the newer luxury zone. Dadonghai is the lively, walkable, mid-range base with the most restaurants, and Sanya Bay, closest to the airport, is the long sunset beach with the Coconut Dream Promenade.
Beyond the sand the island throws in volcanoes, rainforest and religion: the 108-metre sea Guanyin at Nanshan, the cliff-top 'Ends of the Earth' at Tianya Haijiao, the coral diving off Wuzhizhou, and the hot springs and tropical forest parks inland. It is a resort, yes — but a resort with a working fishing port, a real market and a hinterland to escape into.
The one caveat is that Sanya is popular, and popular places attract sharp practice. Overcharging at seafood stalls is a well-documented local problem and the authorities publish price caps in response. Buy from markets, weigh in front of you, and the trip is as relaxed as it looks.

What not to miss — Sanya
Wuzhizhou Island
A small island in Haitang Bay with visibility of up to 27 m and the best snorkelling and diving on Hainan. The ferry and landing ticket is capped daily, so arrive early; the last boat up leaves at 16:00.
Nanshan and the sea Guanyin
A Tang-dynasty-style Buddhist complex built around a 108 m bronze Guanyin standing on the sea. The temple halls, the vegetarian kitchen and the sheer scale of the site make it a half-day on its own.
Tianya Haijiao
The 'Ends of the Earth' — boulders at the water's edge carved with 'Tianya' (sky's edge) and 'Haijiao' (sea's corner). Crowded and symbolic rather than spectacular, but it is the photograph everyone comes for.
Tropical forest and hot springs
The forest park above Yalong Bay was a location for the film 'If You Are the One 2', and its 20-yuan rope bridge is a rite of passage. Inland, the Nantian hot springs run dozens of outdoor pools.
The seafood market system
Buy live seafood by weight at the First Market or a fishing-port market, then hand it to a cook shop that charges a small fee per dish. It is the cheapest and most local way to eat, and half the trip for some visitors.

Getting there and away
Sanya Phoenix International Airport (SYX) sits 20 km west of the city and is Hainan's largest, with direct flights from Beijing, Shanghai, Guangzhou, Hangzhou and most provincial capitals, plus a growing list of international and regional routes. The airport bus runs down the coast; the 8 bus reaches Dadonghai and Sanya Bay for a few yuan, and a taxi to the centre is about ¥40 and 30 minutes.
By rail, the high-speed island line links Sanya to Haikou in about 1 hour 30 minutes, and the Hainan ring line ties the two together. Trains also reach Sanya from the mainland via the Guangdong–Hainan rail ferry, but the crossing is slow and irregular, so flying remains the sane option.
Inside the city, buses 2 and 4 cover the centre, and the famous route 25 threads most of the big sights. In practice most visitors move by taxi or ride-hailing, and the four bays are spread far enough apart that staying in the right one matters more than any single transport tip.

How many days do you need?
Four days is the honest minimum: a full day for Yalong Bay and its jungle park, a day for Wuzhizhou Island, a day for Nanshan plus Tianya Haijiao, and a fourth for the hot springs, the rainforest at Yanoda, or simply more beach. Five days lets you add Dadonghai's evening scene and the Sanya Bay sunset without hurrying. Less than three days and you are spending it all in transit between bays.

Frequently asked questions
When is the best time to visit Sanya?
November to April is the high season — dry, warm and sunny, with sea temperatures of 22–24°C and daytime highs near 28°C. It is also the busiest and most expensive window, especially around Spring Festival. June to September is hotter, wetter and much cheaper, and the summer holiday crowds in July and August are the trade-off.
Which bay should I stay in, Yalong Bay or Dadonghai?
Yalong Bay for polished resorts, the best sand and quiet; Dadonghai for mid-range hotels, walkable restaurants and evening life; Sanya Bay for sunsets and the shortest transfer to the airport; Haitang Bay for the newest luxury resorts and duty-free shopping. There is no single answer — the bays are 30–60 minutes apart, so choose by how you want to spend your days.
Is Wuzhizhou Island worth it?
Yes, if you want the best water on Hainan. Visibility reaches 27 m and the diving and snorkelling are the island's whole point. The ticket including the return ferry is about ¥168, boats run every 15 minutes, the last boat up leaves at 16:00 and the last one back at 17:30. Arrive by mid-morning to beat the queues.
How do I eat seafood without getting ripped off in Sanya?
Buy it yourself. Go to the First Market or a fishing-port market, choose live seafood by weight, and watch the scale — tip the basket to drain the water first. Then take it to one of the surrounding cook shops, which charge a small per-dish fee. Local authorities publish reference price caps, and the market system is both cheaper and more fun than a seafood restaurant on the beach.
Do I need a visa to visit Sanya?
Sanya is covered by Hainan's visa-free entry scheme, which lets travellers from many countries enter the province without a visa for short stays — usually 30 days. Rules and the eligible-country list change, so confirm your passport's status before booking. Within the province you move freely; leaving Hainan for the mainland resets the normal visa requirement.
Is Sanya good for families?
Very. The calm bays, warm shallow water, butterfly valley, underwater world and hot springs all suit children, and the resorts at Yalong Bay and Haitang Bay run kids' clubs. The main caution is the sun — UV is strong year-round, so hats, rash guards and high-factor sunscreen matter more here than almost anywhere in China.
