Hong Kong High Island Reservoir

High Island Reservoir, set within the rugged landscapes of the Sai Kung Peninsula, is a masterpiece of engineering and nature. The reservoir is encircled by the dramatic hexagonal volcanic rock columns of the Hong Kong UNESCO Global Geopark, creating a surreal, otherworldly scenery. This area offers some of Hong Kong's most spectacular hiking and coastal views, a refreshing escape from the city's bustle.

Highlights & What to See

• Hexagonal Rock Columns: Marvel at the towering columns of volcanic tuff, formed 140 million years ago, rising from the sea like giant organ pipes.
• The East Dam: Walk along the massive dam, which features a unique 'sea gate' system and offers panoramic views of the reservoir and the South China Sea.
• Pineapple Dam: A lesser-known spot with a distinctive shape and serene waters, perfect for photos.
• MacLehose Trail Section 1 & 2: Hike this iconic trail for stunning coastal scenery, passing through Long Ke Wan beach and over hills with sweeping vistas.
• Sea Caves & Wave-cut Platforms: Explore the dramatic coastal formations created by centuries of erosion, best seen on a boat trip.

Suggested Time to Spend

Allocate a full day to truly experience the area. Start early to hike the MacLehose Trail sections, which take 4–6 hours. Spend another hour or two exploring the East Dam and rock formations. If you want to include a boat trip to see the sea caves, add another 2–3 hours. The area is remote, so bring plenty of water and snacks—the nearest shops are in Sai Kung town.
