In August, I went to Waisijiao in Zhoushan. Beachcombing was free, and swimming crabs were 25 yuan per jin (500g).
Don’t rush to Zhujiajian South Beach in August—tickets cost 70+, beach chairs 50, and blue crabs at the scenic area stalls go for 58 per jin and are mostly half dead. The crowds are so dense it feels like jumping into the sea.
Step back to the outer ring of Shijiao Island in Shengsi, and you’ll find the true "East China Sea hidden gem" in August:
Shanghai/Hangzhou → Shenjiawan → Shijiao (Caiyuan Town), about 1 hour by car-passenger ferry (Shenjiawan → Shijiao about 1 hour, frequent departures). The outer ring of Shijiao (Jinping + Huanglong + Wulong outer edges) has public beaches with free tide pooling. Around mid to late August before the fishing season opens, blue crabs at Caiyuan Town pier/early market go for 25–30 CNY per jin (Zhujiajian scenic area charges 58+). Staying at guesthouses outside Caiyuan Town or Jihu costs 100–160 CNY per person per night, about half the price of Zhujiajian.
💡 First, clarify: Shijiao is the seat of Shengsi County government (Caiyuan Town). Many only know "Gouqi + Shengshan" (further east and wilder), but the outer ring of Shijiao Island is the entry-level option for free tide pooling, affordable blue crabs, and no crowds—Jihu/Nanchangtu are paid scenic beaches (30–50 CNY), but the outer areas of Jinping Island, Huanglong Dongjutou, and Wulong Bianjiao’ao are all public wild beaches with free access.
📍 Why is the outer Shijiao area the August hotspot?
· Where to find free tide pooling beaches:
· Jinping Island (opposite Caiyuan Town, just through the tunnel): the outer ring "Jinping fishing village → Jinping West Xiezhi" wild beach. At low tide, you’ll find clams, small crabs, and razor clams. Locals often bring buckets here. Free access.
· Outside Huanglong Dongjutou: Huanglong Township (about 20 minutes by ferry from Caiyuan to Huanglong) has a wild beach outside Dongjutou Village with many rocks and shellfish, 90% less crowded than Jihu.
· Outside Wulong Bianjiao’ao: Avoid the paid "Wulong fishing village" area and go to the outer reef beach from Bianjiao’ao to Huicheng Village. Free access.
· Blue crabs really go for 25: After the fishing season opens in mid to late August, the early market at Caiyuan Town pier (5:30–7:30 AM) and the East China Sea fish market (Caiyuan Island market) have local stalls selling blue crabs for 25–30 CNY per jin (depending on size; smaller baskets can be had for 20). Zhujiajian South Beach stalls charge 58+ and the crabs are mostly half dead. For cooking, stalls charge 10–15 CNY per serving (steamed or with scallions and ginger).
· Average temperature is 4–5℃ cooler than Hangzhou: In August, Shijiao has strong sea breezes, daytime temps of 28–30℃, and 24℃+ with a light jacket in the early morning and evening, making it more comfortable than Zhujiajian (which has no shade on the beach).
🚢 How to get there
· From Shanghai: Shanghai Nanpu → Shenjiawan (bus + car-passenger ferry combo ticket about 90–110 CNY), then Shenjiawan → Shijiao Caiyuan Town car-passenger ferry about 1 hour (about 45–60 CNY per person, car extra; pure passenger ticket about 45 CNY); or Shenjiawan → Shijiao express ferry about 45 minutes (70–90 CNY per person, fewer departures, tickets must be booked early).
· From Hangzhou: Drive about 2.5 hours to Shenjiawan, then ferry; or Hangzhou East → Ningbo → Shengsi by bus (Ningbo → Shijiao about 4 hours including ferry).
· Within the county: Caiyuan Town → Jihu/Wulong by shared car 10–15 minutes (10 CNY per person); Caiyuan → Huanglong ferry about 20 minutes.
📅 2-day 1-night tide pooling + blue crab itinerary
Day 1 | Shenjiawan → Shijiao → tide pooling outside Jinping
· Morning ferry to Caiyuan → stay at guesthouse outside Caiyuan Town or Jihu (100–160 CNY per person; inside Jihu scenic area summer rates 300+, staying 200 meters outside Jihu village saves half).
· Afternoon low tide window for tide pooling at Jinping outer wild beach (free): clams, small crabs, razor clams. Bring a small rake + bucket (buying on site is expensive; prepare a 10 CNY set from Taobao in advance).
· Evening back to Caiyuan pier early market (starts at 5:30 AM but you can catch it returning in the evening) + East China Sea fish market: blue crabs 25–30 CNY per jin. Pick live crabs with green shells, tightly closed, and spitting water. Cooking stalls charge 10–15 CNY per serving. Pair with ice-cold beer for about 50–70 CNY per person.
Day 2 | Huanglong Dongjutou → Wulong outer reef → return
· Early morning Caiyuan → Huanglong ferry 20 minutes, tide pooling at Dongjutou outer wild beach (many rocks and shellfish, wilder than Jinping).
· Morning back to Caiyuan, afternoon at Wulong Bianjiao’ao outer reef (free reef beach; if you don’t want to tide pool, walk the outer alleys of Wulong fishing village for free, avoiding the paid "colorful fishing village" area but still great for photos).
· Back to Caiyuan for Shengsi hard cake 10 CNY per box + seafood noodles 20 CNY, then return to Shenjiawan.
💡 Want to add island hopping: Shijiao → Gouqi + Shengshan (further east, bluer but more crowded and expensive), but for 2 days 1 night focusing on "outer Shijiao + blue crabs" is more relaxed. Save Gouqi for next time.
📸 Photo spots (mostly free)
1. Jinping outer wild beach: low tide shellfish + open sea, free, many local stalls.
2. Huanglong Dongjutou: rocks + old fishing village houses, free, less crowded than Wulong.
3. Wulong Bianjiao’ao outer: colorful fishing village outer alleys + rocks, free.
4. Caiyuan pier early market: blue crab baskets + fresh catch, full of local life, free (best 5:30–7:30 AM).
🍜 What to eat (Shijiao prices, not Zhujiajian)
· Blue crabs: 25–30 CNY per jin (Caiyuan pier early market/East China Sea fish market), Zhujiajian 58+
· Cooking fee: 10–15 CNY per serving (steamed/scallion-ginger), find small seafood noodle shops with cooking service
· Shengsi seafood noodles: 20 CNY per bowl (small portions of yellow croaker or pomfret)
· Shengsi hard cake: 10 CNY per box (souvenir)
· Avoid: don’t buy blue crabs for 48+ CNY inside Jihu scenic area, go back to Caiyuan pier for 25; tide pooling tools sold on site at Huanglong/Jinping wild beaches are expensive, prepare a 10 CNY set from Taobao; ferry tickets Shenjiawan → Shijiao are tight in summer, book 3 days in advance via "Shengsi Passenger Transport" WeChat, especially on weekends.
💰 Rough budget estimate (2 days 1 night per person, departing from Shanghai)
· Transport: Shanghai Nanpu → Shenjiawan bus + Shenjiawan → Shijiao ferry round trip about 200 + local shared car about 40 ≈ 240 CNY
· Accommodation: Caiyuan/Jihu outside guesthouse 100–160 CNY per night per person
· Food: daily 60–90 CNY (blue crab share + seafood noodles) ≈ 120–180 CNY
· Tide pooling free + outside Jihu free (Jihu scenic area 30+ optional) 2 days 1 night local expenses ≈ 460–580 CNY per person. Zhujiajian at the same time (stay 300+ eat 100 + South Beach 70 + blue crab 58) easily 1,028+, saving more than half.
📌 Pitfalls to avoid (East China Sea iron rules for August)
1. For blue crabs at 25 CNY, go to "Caiyuan pier early market (5:30–7:30) / East China Sea fish market." Don’t buy at Jihu scenic area or Wulong scenic area stalls (double price). Crabs only get fat after the fishing season opens mid to late August; early August is still the "end of fishing ban," crabs are skinny and expensive. For fat crabs, go between Aug 20 and Sept 10.
2. Check tide times for tide pooling: search "Shengsi tide table," arrive 1.5 hours before and after low tide at Jinping/Huanglong; retreat 20 minutes before high tide. Rocks outside Huanglong are slippery.
3. Ferry tickets are tight in summer: book 3 days in advance on "Shengsi Passenger Transport" WeChat, weekend tickets sell out instantly. Alternative: Shenjiawan → Gouqi then transfer to Shijiao, but it’s a detour.
4. August East China Sea is sunny but windy: SPF 50+ is essential, light jacket for early morning and evening; wear non-slip rubber shoes in Huanglong Dongjutou reef area, avoid holey shoes.
One last note: Zhujiajian sells "East China Sea IP + beach tax + blue crab 58," while outer Shijiao offers "free tide pooling + blue crabs at 25 + Caiyuan pier early market + guesthouses at 100 per person"—if you don’t want to get ripped off by South Beach in August, stepping back to the outer Shengsi main island is the right move. 🦀🌊
