Diving Xiaoliuqiu: rocky entries and green turtles

Green turtles are the reason many divers come to Xiaoliuqiu, and they remain the island’s defining underwater encounter. Diving is organised from shore-based accommodation, with coastal entries and local boat trips over rocky and coral seabeds. It is a practical choice for a three- to five-day stay, allowing several chances to get in the water while leaving room for changing sea conditions. Above water, the same compact island offers coastal walks, viewpoints, villages, kayaking and turtle-focused snorkelling.

Xiaoliuqiu combines shore diving with short boat outings. The seabed is chiefly rocky and coral, and some entries are made over uneven rock rather than from a sandy beach, so getting in and out is part of the dive plan. Currents vary by sector, as do swell and visibility, and conditions can change with rain, runoff and wind. Visibility is commonly around 10 to 30 metres when the water is settled, but suspended particles can reduce it quickly. The diving suits both a relaxed coastal outing and a guided boat dive, rather than a liveaboard routine. Ask which side of the island is workable that day, especially when the prevailing wind makes one coast more comfortable than another. A useful first visit combines a boat dive with a shore dive, giving you two ways to experience the island and less dependence on one type of entry.

Green turtles are Xiaoliuqiu’s main marine attraction, and encounters are regularly reported in both diving and snorkelling. They can be seen throughout the year, with particularly frequent sightings noted from May to October. The appeal is not a long species list, but the repeated possibility of meeting a large turtle at close range in a setting where diving and snorkelling are woven into everyday island life. Keep your distance, let the turtle choose its direction and never form a swimming ring around it. Do not feed, touch or pursue it for a photograph. The quieter approach is also the more rewarding one, because the animal continues its normal movement rather than fleeing from a group of observers.

March to May and October to November are generally the most dependable periods, when the sea is often steadier and visibility more favourable. The rainy season, monsoon conditions, typhoons, strong swell and winter north-easterly winds can all disrupt individual outings, even though diving remains possible at other times of year. Spring and autumn therefore offer the best balance between comfortable access and clearer water. May to October is also a particularly promising period for green turtle encounters. Weekdays and early mornings are usually quieter than sunny weekends and holiday periods, when ferries, snorkelling spots and popular entries become busier.

The destination can suit beginners as well as experienced divers, provided a local guide assesses the entry, swell and current on the day. There is no special qualification beyond the certification appropriate to the planned dive, whether BSAC, PADI or SSI. Beginners should not treat the easy ferry journey as proof that every water entry is easy. Rocky access, changing conditions and surface movement deserve a proper briefing. More experienced divers will appreciate the flexibility of combining shore and boat diving, but should not expect a deep-profile or current-focused destination by default.

From London Heathrow, Gatwick or Manchester, the journey must be planned around reaching Donggang in southern Taiwan. Xiaoliuqiu has no airport, so Donggang is the departure point for the compulsory ferry. Donggang is generally reached by road from Kaohsiung, with the drive taking about an hour and a half depending on traffic, followed by a crossing of roughly 20 to 30 minutes. Build generous connection time into both directions: weather and sea conditions can delay or cancel departures. Do not put an international flight immediately after the planned return crossing. Once on the island, accommodation and dive centres are spread between villages, so getting about may mean walking, using a scooter or arranging a centre shuttle. Check the departure port and return quay on the ferry ticket.

Bring proper water shoes or boots. Several entries are rocky, and ordinary beach footwear is not a substitute when carrying kit over uneven ground. Ask about the day’s wind before settling on a site, rather than choosing by name alone, and favour a morning dive when visibility is often better and popular spots less crowded. If possible, avoid weekends and holidays. Keep a buffer around the ferry on both sides of the stay, with a full spare day before an international flight if the connection matters. Do not plan the whole visit around one busy snorkelling location, because a crowded entry can spoil the experience. In the water, never stand on coral or coral rock, and never swim directly at a turtle, cut across its path, chase it or surround it. Check the ferry quay again before travelling, and combine a boat dive with a shore dive so one changing access route does not determine the entire trip.

Most visits are arranged as a land-based stay of three to five days. Accommodation and diving are spread through the island’s villages, so the right base depends on where you plan to spend your time and whether a shuttle is available. Leave mornings for diving, keeping flexible time for the sea and ferry schedule. Non-divers can join turtle snorkelling, walk the coast, visit viewpoints and villages, or kayak when conditions allow. A quiet final day on land is sensible before an international flight.
