Dapeng Peninsula, Shenzhen tide times

The Dapeng Peninsula projects southeast from Shenzhen's eastern edge into Daya Bay, forming the only significant stretch of undeveloped coastline within an hour of one of the world's most densely built cities. Shenzhen's 17 million residents live primarily on the western side of the municipality; Dapeng, designated as the Dapeng New District in 2011, has retained its natural coast through protected status. Tidal regime is mixed semidiurnal: two unequal high waters and two unequal low waters per day. Mean tidal range at Daya Bay is approximately 1.2 to 1.5 m above chart datum.

Dongchong and Xichong beaches at the peninsula's southern tip are the destination. Neither has road access. Dongchong is reached by a 5 km hiking trail over the ridge from Nan'ao township, descending through subtropical forest to a 1.5 km crescent of white-grey sand; Xichong, 2 km further east, is accessible by boat from Nan'ao or by a separate 8 km trail. Both beaches face south into the South China Sea and are sheltered from the northeast by the peninsula ridge. The water clarity here is notably better than the Pearl River Delta coastline — Daya Bay, away from the Pearl River plume, has visibility of 5 to 10 m in winter and spring.

At low water, the rocky headlands flanking both beaches expose wide tidal reef platforms. The reef is mixed substrate — granite boulders, coralline rubite, and a sparse hard coral community in the shallow subtidal (0.5 to 2 m depth). Rock pools at low water contain mantis shrimp, small blennies, sea urchins, and banded coral shrimp. The best reef walking is at the lower of the two daily low waters, when the larger tidal inequality exposes the fullest extent of the platform — this lower low water occurs once per day and is typically 0.3 to 0.5 m lower than the higher low water.

Nan'ao township at the base of the peninsula has guesthouses, seafood restaurants, and the boat pier for water access to Dongchong and Xichong. The boat from Nan'ao to Dongchong takes 20 minutes and runs on demand when enough passengers (typically 6 to 10) are waiting; price is around 30 to 50 RMB per person. Arriving by the hiking trail and returning by boat (or vice versa) avoids retracing the same route.

The Dapeng Ancient Fortress (Dapeng Suocheng), a Ming-dynasty garrison fort built in 1394 in the township of Dapeng, is a 35-minute drive from Dongchong. The fort walls and several of the internal buildings survive largely intact — one of the best-preserved coastal military fortresses in Guangdong. General Liu Jin-Biao and General Lai En-Jue, both from Dapeng, played significant roles in the First and Second Opium Wars; the garrison's local connections to 19th-century resistance are documented in the fort museum.

Tide predictions on this page come from Open-Meteo Marine, a global ocean model. Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — model-derived, not from a local gauge.
