This trail is a world-class visual feast that showcases Hong Kong’s unique geological wonders and stunning coastlines. Starting from the 【East Dam (東壩)】, you first ascend to the 【Biu Tsim Kok • Viewing Platform (標尖角 • 觀景台)】 for a panoramic view of the High Island Reservoir and the vast seas of Leung Shuen Wan. Afterwards, stroll along the 【High Island Geo Trail (萬宜地質步道)】 to get an up-close look at the magnificent hexagonal rock columns. Along the way, you’ll witness nature’s craftsmanship, including the profound 【Kwun Mun Hole • Sea Cave (官門遺洞 • 海蝕洞)】 and the massive 【Breakwater (防波堤)】 made of giant dolos blocks, offering a striking contrast between human engineering and natural forces. The second half of the journey takes you into more rugged and pristine territory. You’ll pass the tranquil 【Chicken Leg Wan (雞脾灣)】 and the hidden, mystical 【Kim Chu Wan (撿豬灣)】, where you can enjoy crystal-clear waters and rocky shores. The adventure culminates at the iconic 【Po Pin Chau (破邊洲)】, a sea stack that looks as if it were split from the mainland by a giant axe. Looking out at its unique tubular rock columns provides the most breathtaking finale to this journey through the Global Geopark. The entire route covers approximately 12 km and takes about 5 hours to complete. This scenic trail is packed with stunning geological wonders and natural landscapes, making it a perfect choice for intermediate hikers looking for a rewarding challenge.

Route Overview
East Dam (東壩) → Biu Tsim Kok • Viewing Platform (標尖角 • 觀景台) → High Island Geo trail (萬宜地質步道) → Kwun Mun Hole • Sea Cave (官門遺洞 • 海蝕洞) → Dolosse / Breakwater (防波堤) → Chicken Leg Wan (雞脾灣) → Kim Chu Wan (撿豬灣) → Po Pin Chau (破邊洲)
【Start】 Setting off from the 【East Dam (東壩)】, you’ll first walk along a flat concrete path. This section is well-shaded and very easy to tackle. Shortly after starting, you’ll pass the 【East Dam • Pavilion (東壩 • 涼亭)】, which is a great spot to take a breather. Continuing on, you will reach the 【Biu Tsim Kok • Viewing Platform (標尖角 • 觀景台)】, which offers a stunning 270-degree panoramic view. From here, you can overlook the entire East Dam and 【Long Ke Wan (浪茄灣)】, while spotting 【Tsang Pang Kok Tsui (罾棚角咀)】 and 【Po Pin Chau (破邊洲)】 in the distance.
【Mid-Section】
Moving on from the viewing platform, you’ll arrive at the 【High Island Geo Trail (萬宜地質步道)】. This is one of Hong Kong’s most famous geological landmarks, where you can see world-class hexagonal rock columns, fault breccia, and S-shaped curved columns. These spectacular wonders were formed by a super-volcano eruption 140 million years ago. Following the trail leads you to the 【Kwun Mun Hole (官門遺洞)】 and the 【Sea Cave (海蝕洞)】. The Kwun Mun Hole is a well-preserved relic from the Qing Dynasty (清朝), offering a glimpse into Hong Kong’s history, while the Sea Cave — formed by relentless wave erosion—features amazing natural echoes that are truly impressive.
Continuing past the cave, you’ll reach the 【Breakwater (防波堤)】. Composed of thousands of massive dolos blocks, it is incredibly grand and serves as an ideal photo spot to capture the majestic sea views and the sheer scale of the engineering.
【Finish】
Next, follow the trail to 【Chicken Leg Wan (雞脾灣)】, a beautiful beach equipped with camping facilities that makes for a perfect rest stop. Keeping along the path, you’ll hit 【Kim Chu Wan (撿豬灣)】, another scenic beach where you can relax and enjoy the natural surroundings.
Finally, a short trek from the beach leads you to the iconic 【Po Pin Chau (破邊洲)】. This unique geological site features breathtaking sea cliffs and extraordinary rock formations. After taking in the sights of Po Pin Chau, head back the way you came to the 【East Dam • Pavilion (東壩 • 涼亭)】 to wrap up your hiking adventure.

Additionally, there are marine sandstone and mudstone from the 【Permian Period (二疊紀)】 (approx. 280 million years ago) outcropping at 【Ma Shi Chau (馬屎洲)】, as well as Early Jurassic marine sandstone and siltstone (approx. 180 million years ago) on both sides of the 【Tolo Channel (赤門海峽)】.
The red sandstone, siltstone, conglomerate, and breccia (approx. Late Cretaceous) found at 【Port Island / Chek Chau (赤洲)】, 【Double Haven / Yan Chau Tong (印洲塘)】, and several islands in 【Mirs Bay / Dapeng Wan (大鵬灣)】 indicate an arid terrestrial geological environment at that time. Finally, the siltstone and shale exposed at 【Tung Ping Chau (東平洲)】 belong to the 【Paleogene Period (古近紀)】 (approx. 56 – 32 million years ago), making it the youngest rock formation in Hong Kong. These sedimentary rocks, shaped by varying geological and geographical conditions, have formed a diverse array of geomorphological landscapes.
