Changxing Island Leisure Loop: Citrus Orchards & the Sea-Dyke

Begin at Juyuan Farm Stay (桔园农庄, 前卫支路565号), a citrus farm stay that rents mountain bikes to walk-ins, reported around ¥50–58 per session, with basic bikes whose brakes are worth checking before the saddle (confirm current policy and hours). The loop's first kilometre runs south on 前卫支路, the quiet, partly metasequoia-lined lane that links the farm stay to the island's working south: flat fields, drainage channels, citrus rows and the odd farm vehicle. This is Changxing's double character in miniature, an island that builds some of the world's biggest ships on one shore and grows oranges on the other. The shipyards along the south shore are closed industrial ground, so the loop rides the public roads and keeps the working yards at a respectful distance. The surface is sealed and smooth, and the morning light across the orange rows is the day's first proper photo stop.

Photo suggestion: The citrus rows along 前卫支路 photograph best mid-morning, before the wind picks up.

At the south corner the loop turns onto Pan Yuan Highway (潘圆公路), the island's metasequoia-lined east–west spine, smooth asphalt, few traffic lights and, on the reported ~500 m avenue stretch, little motor traffic (confirm the exact length on-site on the day). This is the loop's fast section and its shade highlight, and it carries the ride's signature moment: at the 潘圆公路立交桥 the road passes under the G40 approach, the elevated concrete of the tunnel-and-bridge system sweeping overhead on its way from the river tunnel to the cable-stayed span, the 'bridge underpass' photo stop community reports describe. Community reports call the underpass the loop's most photogenic moment, and the geometry arrives with little warning, so check the mirror and hold the line. The Yangtze River Bridge itself (上海长江大桥, the G40 span with its 90 m+ towers) stays visible to the north through the ride, a constant landmark, and the metasequoia rows resume on the far side. The avenue returns the loop to 前卫支路's junction, where the road bends south for the last kilometre back to the farm stay.

Caution: The G40 interchange carries merging motor traffic, ride single-file through the underpass and watch for cars entering and leaving the expressway approaches.

From the loop's south corner the ride can extend east onto the island's signature stretch: the sea-dyke (海堤), the continuous flood-dike road along the Yangtze, flat, open and wind-exposed, with giant white wind turbines (风力发电机组) and reed beds (芦苇荡) between the rider and the river. The dike is working flood defence first and a cycling lane second, and the wind is the day's constant companion; on gusty days the turbines' rhythm is the only sound, and the reed beds give the bank its texture, the island's quiet margin. Note: the direct dike line from 前卫支路 toward the harbour is interrupted around the shipyard zone, and the dike lane is not on AMap's routing network, most riders rejoin via 潘圆公路 and ride the best dike sections around the harbour, so the extension's exact line needs on-site confirmation (). The view faces the Yangtze and the bridge to Chongming, and the flat, open miles are the ride's emotional core.

Caution: The dike is exposed: hold the wind line on gusty days, secure hats, and expect occasional farm and maintenance traffic.

The dike extension's anchors sit at the island's south-east corner: the Changxing–Hengsha Fishing Harbour (长兴岛横沙渔港) is a working harbour of boats, nets and quayside life, with farm restaurants around 渔港环路 for the day's seafood lunch, and the First Beach of the Yangtze (长江第一滩) is the harbour's ~800 m shoreline promenade, the sunset spot community reports rank above everything else on the island, with a closing time commonly reported around 16:30 (confirm on the day, and time the dike ride so the sunset lands before the gate). The promenade's railings and benches make it a natural rest point, and the restaurant row serves the day's catch with the harbour working within sight. The harbour's activity level varies by season and its public access is, confirm on-site. Riders who come this far can return via 潘圆公路 east of the island, which is where the 50–55 km Grand Loop page takes over.

Photo suggestion: The First Beach sunset is the day's best shot, arrive before the reported ~16:30 closing and shoot into the west.

The other direction of extension is west along 潘圆公路 to the Country Park: Changxing Island Country Park (长兴岛郊野公园, 秋柑路666号) is Shanghai's largest country park, reported at nearly 30 km², free with a WeChat mini-program reservation, and pet-friendly with a pet fee commonly reported around ¥40 (confirm current). Inside, citrus groves with 50+ varieties reported, rose and lawn areas and family facilities make it the loop's natural second half for riders with children, families typically ride the park's internal paths after the small loop and let the children's facilities set the pace. The gates are the extension's water, food and toilet anchor. Just beyond, Pan Shi Park (潘石公园) is the island's western green space, themed orange after the citrus identity, 'orange Pan Shi', a short spur with lawns and orange-themed planting. The community ~14.5 km 'extended circuit' figure is this reading: the small loop plus the park leg, ridden as a half-day.

Caution: The Country Park requires advance reservation (WeChat mini-program), book before riding out on a weekend, or the gates may turn you away.
