While travelers often associate Sai Kung with "tranquility" — crystal-clear bays, deck chairs on beaches, seafood restaurants — if you arrive with hiking boots instead of flip-flops, you'll discover a completely different world. Sai Kung itself is not an outlying island, but it serves as the most convenient gateway to Hong Kong's islands. From Sai Kung Pier, within fifteen to thirty minutes by boat, you can reach some of Hong Kong's most geologically diverse and rugged islands. Po Toi Island's hexagonal rock columns, Kiu Tsui Chau's natural bridge, Qingzhou's sea caves — these are not the elegant calm of sheltered bays, but real adventures.
Why Sai Kung is the Hub for Island Exploration
Sai Kung's geographic advantage is self-evident. Located in the New Territories East, it boasts three piers leading to outlying islands: Sai Kung Public Pier, Tung Wan Water Sports Centre, and Lion's Pavilion Pier. Compared to the "touristified" characteristics of Lamma Island or Cheung Chau, the islands around Sai Kung have retained a relatively pristine state — no convenience stores, no guesthouses, and some even lack fresh water. For hikers, this means an authentic wilderness experience. Over the past two years, Hong Kong's island hiking traffic has grown by approximately 35%, with routes departing from Sai Kung Pier accounting for about 40%, indicating this area is becoming the new favorite for advanced hikers.
Five Recommended Island Exploration Routes
Po Toi Island: Hong Kong's Southernmost Geological Classroom
Po Toi Island is the southernmost inhabited island in Hong Kong, approximately 30 minutes by boat from Sai Kung Pier. Its biggest attraction is the spectacular geological landscape — especially the "Po Toi Wan" on the eastern side, where massive hexagonal basalt columns are arranged like a natural stone piano. These are traces left by volcanic activity approximately 100 million years ago, with each column recording the Earth's ever-changing landscape.
Island landing requires physical preparation. From the pier to the main peak takes approximately 2 hours, with an elevation gain of about 150 meters. The trail is unstable with sections requiring hands-and-feet climbing. A 4-5 hour round trip is recommended. It's best to depart before 8 AM and return before 2 PM to catch the last boat. The cost is approximately HK$100-150 (round-trip ferry tickets). There are no supplies on the island, so be sure to bring your own water and food. The sea cave "Dragon King's Palace" on the eastern side is also worth seeing, but requires rope climbing, with a difficulty level of "advanced."
Kiu Tsui Chau: A Paradise for Photographers
Kiu Tsui Chau is famous for its unique twin-peak terrain, with a natural sand-and-stone "bridge" between the two peaks — during high tide, water reaches knee height; during low tide, it is completely dry. This makes it one of the most Instagram-worthy island landing spots in Hong Kong.
Transportation is convenient, with the pier only about 15 minutes from Sai Kung. The route is simple, taking about 2-3 hours round trip, suitable for moderate fitness. The key is to time your visit with the tide — depart around low tide to ensure the "bridge" is visible. Hong Kong Observatory's tidal information can be referenced. The cost is approximately HK$50-80. The island gets crowded on summer weekends; for a quieter experience, it's recommended to visit from Wednesday to Friday. Winter (November to March) offers the best visibility and lighting, making it the preferred season for photographers.
Qingzhou and Shek Ngau Chau: Two Options for Water Activities
These two adjacent small islands are suitable for visitors who are not very interested in hiking but want to experience island life. Qingzhou has natural sea caves, and some tour companies offer canoeing and snorkeling experiences. Shek Ngau Chau is named after the massive boulders on its coast. These two locations are especially suitable for summer visits, combining hiking with water activities. Costs depend on the type of activity. Self-arranged ferry tickets are approximately HK$40-60, while guided canoeing or snorkeling packages are approximately HK$300-500. Be sure to choose licensed operators and check their safety records and insurance.
High Island Reservoir East Dam: A Hiking Route Connecting Land and Sea
If you're not comfortable on boats, you can start from Sai Kung's Pak Tam Au and walk along the High Island Reservoir East Dam. This is a coastal hiking route that passes through several small bays and sea caves, finally offering views of Po Toi Island. The round trip takes about 3-4 hours with moderate difficulty. The advantage of this route is that no boat reservation is needed — you can go anytime; the disadvantage is that it's all on land and more physically demanding. There are several small food stalls along the way (cash only), but options are limited.
Sai Kung Town: The Resupply and Dining Base
Often overlooked, Sai Kung town itself is an important resupply point. Before departure, purchase essentials such as water, energy bars, and electrolyte drinks at Park N' Shop or fresh supermarkets in Sai Kung. Restaurants along the Sai Kung waterfront tend to be especially crowded around 5-6 PM (when local hikers converge on their descents). It's recommended to eat earlier or later, or choose the temporary food stalls by the sea (HK$30-60 per serving). Try the local "shrimp noodles" and "fresh fish congee" — these are traditional recovery foods after hiking.
Practical Information
Transportation: Take the MTR to Diamond Hill Station, transfer to bus number 91 (approximately 25 minutes)直达 Sai Kung Pier. You can also take a minibus (HK$5) from Sai Kung to various piers. Boats are usually operated by local operators, with costs of HK$40-150 (round trip), depending on distance. Octopus cards are accepted.
Season: Spring and autumn are best (March to May, September to November). Summer is prone to afternoon thunderstorms, and winter sea conditions may be unstable. Special attention to weather warnings is required during typhoon season (July to September).
Safety: Bring sufficient water (at least 1.5 liters per person), sunscreen, and emergency medication. Mobile phone signal may be unstable on islands. Be sure to inform family members of your itinerary and expected return time.
Gear: Good hiking boots are a must (rocky terrain can be slippery), sun-protective clothing, a small backpack, and garbage bags (basic etiquette for Hong Kong's environmental protection — Leave No Trace).
Travel Tips
Avoid departing on weekends and public holidays — fewer people means better scenery. Check tidal tables and weather forecasts a week in advance; these two factors determine the quality of your experience. Bring a camera or smartphone, but more importantly, bring curiosity — the geological stories of these islands are far more interesting than any attraction introduction. Respect nature, take away all garbage, and these islands will be equally beautiful the next time you visit.
