High Island Reservoir

High Island Reservoir, set in the dramatic volcanic landscape of Hong Kong's Sai Kung Peninsula, is a striking fusion of engineering and raw nature. The reservoir, completed in 1978, is surrounded by rugged hexagonal rock columns formed by ancient volcanic eruptions, creating a surreal, otherworldly terrain. This area is a paradise for hikers, kayakers, and nature lovers, offering some of Hong Kong's most spectacular coastal scenery.

Highlights & What to See

• Hexagonal Rock Columns: Marvel at the towering basalt columns along the reservoir's shore – one of the world's finest examples of volcanic rock formations.
• East Dam of High Island Reservoir: A massive sea wall where you can walk along the top, taking in panoramic views of the South China Sea and the dramatic rock formations.
• MacLehose Trail Section 1 & 2: The reservoir is a key point on this famous trail; hike Section 1 for a relatively easy walk with stunning sea views, or tackle Section 2 for a more challenging coastal trek.
• Kau Sai Chau and Yim Tin Tsai: Nearby islands accessible by kayak or small boat, offering secluded beaches and a historic Hakka village with a salt pan.
• Geopark Visitor Centre: Learn about the unique geology and ecology of the Hong Kong UNESCO Global Geopark at the centre near the Sai Kung town pier.

Suggested Time to Spend

Allocate at least half a day to explore the reservoir and its immediate surroundings. For a relaxed visit, spend 2–3 hours walking the East Dam and nearby trails, then combine with a kayak trip to the adjacent islands. If you're hiking the MacLehose Trail, plan for a full day (6–8 hours) to cover Sections 1 and 2, with stops for photos and a picnic. The area is best visited in the cooler months from October to March.
