It is the island’s best-known diving spot, with visibility that regularly beats the mainland shore and a compact set of reefs, beaches and family attractions. This article covers the Fenjiezhou Island guide essentials: how to get to Fenjiezhou Island, the best time to visit Fenjiezhou Island, the things to do at Fenjiezhou Island, the Fenjiezhou Island entrance fee, and a set of Fenjiezhou Island travel tips.

The Boundary Between Two Seas
Fenjiezhou sits on a submerged ridge where the warm, calm currents of the south meet cooler northern water — the “boundary” of its name. That meeting makes for unusually clear visibility and a richer reef than most of the Hainan shore. The island itself is a small rocky hill fringed by white-sand coves and wooden walkways, with a cable car linking it to the mainland pier.
Unlike the busier resort beaches, Fenjiezhou is managed as a marine park: the reefs are protected, the dive operators are licensed, and the water stays cleaner. It works for serious divers and for families who just want a calm swim and a dolphin show.
Best Time to Visit Fenjiezhou Island
October to April. Hainan’s dry, cool season and the prime window. Days run 22–28°C, the sea is calm, and visibility for diving peaks. This is the best time to visit Fenjiezhou Island.
May to September. Hot and humid, with afternoon rain and the occasional typhoon in July–September. Visibility dips after storms, but prices fall and crowds thin.
Chinese New Year and National Day week. Avoid if possible — the island caps visitor numbers but the ferries and roads clog.
The water is warmest in summer but least clear; spring and autumn give the best balance.
How to Get to Fenjiezhou Island
The island has no airport; you reach it by high-speed rail to Lingshui, then a short road transfer and a cable car or ferry to the island.

Most visitors come from Sanya as a day trip. Our Sanya beach travel guide covers the southern base and its other coves, while our Haikou travel guide explains the northern gateway and its old town. For more east-coast stops, our Wanning travel guide covers the surf town just south, and if you want island-hopping beyond Hainan, our Beihai travel guide and Zhuhai travel guide point to Guangxi and Guangdong coastal islands.
Staying in Sanya? Fenjiezhou is an easy morning train to Lingshui plus a cable car — book the dive pack online and beat the midday ferry rush.
Things to Do at Fenjiezhou Island
Scuba diving on the reef
The headline of the things to do at Fenjiezhou Island. Several marked sites around the islet suit beginners and certified divers, with soft coral, parrotfish and the occasional turtle. A Discover Scuba intro including gear runs about ¥400–600; certified dives are cheaper per dive if you book a pack.
Snorkelling
Shallow buoyed areas near the north cove let non-divers see the reef with a mask and fins. Gear rental is cheap; go early for calm water and light.
The beaches and cliff walk
White-sand coves linked by wooden boardwalks, plus a short climb to a hilltop sea-view pavilion. Quieter than the mainland resort strips and cleaner.
Marine shows and family zone
A dolphin and sea-lion show, a small aquarium and glass-bottom boat rides occupy the non-divers. Family-friendly without being a theme park.
Sunset from the pier
The mainland pier at golden hour, with the island silhouetted and fishing boats returning, is the easy photo finish to the day.

Lingshui county. Closer and cheaper, with a few hotels near the station, but fewer amenities and patchy foreigner registration at small properties.

Only here for the diving? Sleep in Sanya, take the morning train to Lingshui, and you can be snorkelling before the crowds arrive. A dive pack booked ahead means no waiting at the pier for your gear. Save the beach clubs for the evening — the reef is the real reason to come, and the calm morning water shows it best.
