# Dadonghai Bay, Sanya > Dadonghai is Sanya's city beach, about 3 km from downtown: a crescent of sand roughly 3 km long, free and open around the clock. Swim in the daytime, inside the netted zone watched by lifeguards. Cafés, bars and shops line the streets behind it. Allow 2 hours; the dry winter season is the most comfortable time to go.

Yes — as a base, and for an easy beach day with dinner afterwards. Dadonghai is the only Sanya bay where you can walk from the sand to noodle shops, malls and bars without a taxi, and the beach is **free, around the clock**. It is not Sanya's best water. The sea is cloudier than at [Yalong Bay](https://yesgo.io/china/sanya/yalong-bay), boats and jet skis work the middle of the bay, and in high season the sand is packed. If clear water is the whole point of your trip, stay or spend a day at Yalong Bay; if you want the beach and the city together, Dadonghai is the practical choice. > **Swim only inside the buoys** This is a working city bay: speedboats, jet skis and banana boats run along the shore. Swim inside the roped-off zone, where lifeguards sit on the tower. If they whistle you out or close the water, get out — rip currents form near the shore when the waves pick up. Don't swim after dark. ## Dadonghai beach and swimming The beach is a crescent of about 2.8–2.9 km with a gentle sandy slope into the **South China Sea**; near the rocks at each end the bottom turns stony. Entry is free and the sand is open 24 hours. One guide gives the swimming zone hours as 8:30–18:30 — check the signs on the beach. Sunshades, loungers and showers belong to the beach cafés and rental stands, and prices are negotiable, so agree on one before you sit down. Mornings are cooler, calmer and less crowded — the best time for swimming with children. Don't leave bags unattended on the sand. Water sports are run from the beach: banana boats, jet skis, parasailing, boat dives and a semi-submersible for looking at the seabed. Ask what the price includes and haggle — rates are not fixed. ## How to get to Dadonghai 1. From downtown (Jiefang Road) it's about 3 km. A **taxi** takes 10–20 minutes and, unofficially, costs around 15 yuan. DiDi runs inside Alipay in English and accepts foreign Visa or Mastercard. 2. **City buses 2 and 8** run from downtown to the Dadonghai Square stop (大东海广场, Dadonghai Guangchang). Fares start at 2 yuan, paid in cash (no change) or by QR code. Sources disagree on route numbers, so check them in Alipay or Amap before you go. 3. From the stop, walk across the square to the sea — 3–5 minutes. 4. From Sanya Phoenix Airport (SYX) it's about 15 km as the crow flies: a taxi takes 30–45 minutes, unofficially 40–80 yuan; city bus 8 is cheaper and takes about an hour; some guides also list airport bus line 1 — check the numbers on arrival. 5. Carry on along the coast to Yalong Bay, about 20 km east — easiest by taxi. ## Best time to visit Dadonghai **November to March** is the sweet spot: daytime highs around 25–28 °C, little rain, and the sea about 23 °C in January and February — fresh but swimmable. It gets hot from April, and May to October is humid with heavy tropical downpours. Typhoon season runs from roughly June to October, peaking in August and September. When a storm warning is issued, the beaches close to swimmers and boat trips are cancelled, so leave a spare day in a summer or autumn itinerary. From December to April the typhoon risk is close to zero. ## Things to do in Dadonghai - **Walk the seafront** from Dadonghai Square to the eastern end of the bay — early morning or after sunset. - **Catch sunrise** from the east side of the bay; for sunset, head up to [Luhuitou Park](https://yesgo.io/china/sanya/luhuitou-park) for views over the bays and the city. - **Try a water sport** — jet ski, parasailing or a boat dive, booked on the sand. - **Spend the evening on the bar strip** along the shore, with seafood restaurants and live music. - **Day-trip to quieter bays** — Xiaodonghai, 4–6 km away, for calm swimming, or Yalong Bay for Sanya's clearest water. ## Where to eat Everything is within a few blocks: noodle shops, Chinese and Russian-menu cafés, Western bars and chain fast food in the malls. Seafront restaurants are convenient but cost more than places one street back. For seafood the local way, take a taxi to **Sanya First Market**, about 3 km north-west in downtown: you pick live fish and prawns at the stalls and a restaurant nearby cooks them for a fee. Watch the weighing and agree on the cooking price first. The small evening market in Dadonghai itself is a way to fill an hour, not a food destination. ## Money, visas and staying connected Hainan has its own visa-free scheme: ordinary passport holders from 61 countries — including the US, the UK and Russia — can stay up to 30 days for tourism or business, entering through any open Hainan port and staying within the province. China's nationwide visa-free and transit rules are separate — check your nationality before booking. Flights land at Sanya Phoenix Airport (SYX), 30–45 minutes from Dadonghai. China runs on QR payments. Link your Visa or Mastercard to **Alipay or WeChat Pay** before you fly; international cards also work at hotels and big malls but rarely at small cafés or beach stands, so carry some cash yuan in small notes. Google, WhatsApp and Instagram are blocked in China — sort out roaming or an eSIM that routes abroad before departure. ## Dadonghai vs Yalong Bay vs Sanya Bay | | Dadonghai | Yalong Bay | Sanya Bay | | --- | --- | --- | --- | | Where | ≈ 3 km from downtown | ≈ 20 km east, ≈ 30 min from downtown | Along the city, closest to the airport | | Water | Average, busy with boats | Sanya's clearest | Weakest for swimming | | Around it | City: cafés, shops, bars | Resort hotels, a drive to town | City and a long promenade | | Best for | Beach and city on foot | Swimming and snorkelling | Walks and sunsets | Base yourself in Dadonghai for convenience, give Yalong Bay a full day for swimming, and save an evening for sunset on the Sanya Bay promenade. ## Before you go: checklist - [ ] SPF 50 and a hat — the sun is fierce even in winter - [ ] Water shoes for the rocky ends of the bay - [ ] Small notes in cash yuan for loungers and the bus - [ ] Alipay or WeChat Pay set up with a working card - [ ] A translation app that works without a VPN - [ ] Weather warnings checked, if travelling in summer or autumn ## Sanya's beaches and bays compared Every bay and seaside spot in Sanya rated by YesGo. - [Phoenix Island](https://yesgo.io/china/sanya/phoenix-island) — YesGo score 43/100 (Yes, if nearby) · 45 min · Free from the shore; island by booking - [Dadonghai Bay](https://yesgo.io/china/sanya/dadonghai) — YesGo score 38/100 (Yes, if nearby) · 2 h · Free - [Yalong Bay](https://yesgo.io/china/sanya/yalong-bay) — YesGo score 24/100 (Yes, if nearby) · 3 h · Beach free; rentals extra - [Tianya Haijiao](https://yesgo.io/china/sanya/tianya-haijiao) — YesGo score 21/100 (Yes, if nearby) · 2 h · Free, advance booking required - [Nanwan Monkey Island](https://yesgo.io/china/sanya/nanwan-monkey-island) — YesGo score 20/100 (Yes, if nearby) · 2 h 30 min · ≈ ¥154 incl. return cable car - [Nanshan Buddhist Cultural Zone](https://yesgo.io/china/sanya/nanshan-temple) — YesGo score 19/100 (Yes, if nearby) · 3 h · ≈ ¥130–160 with park train - [Yanoda Rainforest Park](https://yesgo.io/china/sanya/yanoda) — YesGo score 17/100 (Yes, if nearby) · 3 h 30 min · ≈ ¥168 incl. park shuttle - [Wuzhizhou Island](https://yesgo.io/china/sanya/wuzhizhou-island) — YesGo score 16/100 (Yes, if nearby) · 4 h · 144 yuan incl. return ferry ## Three bays in a day Morning swim in Yalong Bay's clear water, lunch and the beach in Dadonghai, sunset from the Luhuitou hilltop. 1.

Sanya Bay is the long city beach on the other, western side of Luhuitou. ## Tips - Swim in the morning: calmer water, fewer boats and gentler sun. - For sunset, go up to Luhuitou Park: the hilltop looks over both Dadonghai and Sanya Bay. - Loungers, banana boats and jet skis have no fixed prices — agree before you start. - Seafood is better value bought at Sanya First Market and cooked there than ordered on the seafront. - Travelling in summer or autumn? Keep a spare day in case a storm closes the beach. ## Questions ### Is Dadonghai beach free? Yes.

Shoreline figures differ — 2.8 km (China Daily), 2.9 km (Travel China Guide, East China Trip), about 3 km (Top China Travel) — so we show a range; distance from downtown ranges from 2 to 4 km by source. Bus numbers differ between sources; routes 2 and 8 appear in several but are marked “verifying”. The swimming-zone hours (8:30–18:30) come from one source only. Sea temperatures and typhoon risk are climate averages and unofficial, as are taxi fares. ## Sources - China Daily (chinaservicesinfo.com): Dadonghai Tourism Area — free entry, shoreline length, buses, water sports - Travel China Guide: Dadonghai — shoreline, hours, buses, distances - Top China Travel and East China Trip: Dadonghai Beach — season, swimming zone hours, airport buses - travelto.ru: best beaches of Dadonghai — swimming zones, lifeguards, distances to Xiaodonghai and Yalong Bay - China Highlights: guide to Sanya's bays - Weather2Travel and seatemperature.info: Sanya climate and sea temperature - English Wikipedia: Dadonghai; Wikidata Q9857467 - National Immigration Administration of China (NIA): Regional Visa-Free Entry Policies for Foreign Nationals, 20.08.2026 — Hainan visa-free entry - Baba Goes China: where to stay in Sanya — paying by card - T—Zh (t-j.ru): paying in China — Alipay and WeChat Pay with a foreign card --- This is the Markdown version of a YesGo page for AI assistants.
