Red Sea Lake (Hong Haizi) Travel Guide: A Hidden Alpine Lake in Sichuan
Introduction: Why Visit Red Sea Lake (Hong Haizi)?
Hidden deep in the mountains of the Western Sichuan Plateau lies Red Sea Lake, locally known as Hong Haizi. Unlike famous destinations such as Jiuzhaigou or Daocheng Yading, this high-altitude lake remains quiet, understated, and deeply personal. Sitting at 4,200 meters (13,780 ft) above sea level, Red Sea Lake is often described as a “mirror of the sky”, reflecting snow mountains, drifting clouds, and the inner calm of those who visit.
As someone who has explored Western Sichuan many times, Red Sea Lake stands out not for dramatic crowds or infrastructure, but for its stillness. This guide shares what makes Hong Haizi special, how to visit, and why it may be one of the most rewarding hidden lakes in Sichuan.

Where Is Red Sea Lake (Hong Haizi)?
Red Sea Lake (Hong Haizi) is located in Jiagenba Town, Kangding City, within Ganzi Tibetan Autonomous Prefecture, Sichuan Province. The lake is known in Tibetan as “Jia Ga La” and was formed as a glacial tarn, carved by ancient ice movement rather than river flow.
Because of its mineral-rich water and changing light conditions, the lake shifts color throughout the day—from pale turquoise under strong sun to deep jade blue on cloudy afternoons. On calm mornings, thin mist often floats above the surface, with Bijia Mountain rising quietly in the background.

What Makes Red Sea Lake Special?
Mirror-Like Reflections
The most iconic feature of Red Sea Lake is its near-perfect reflection. When the wind drops, snow mountains, clouds, and sky merge seamlessly with the water, making it hard to tell where the land ends and reflection begins.
Photography tip: A polarizing filter helps reduce surface glare and enhances reflection clarity.
Glacial Landscapes
Large glacial erratics line the lakeshore, their surfaces shaped by wind and ice over thousands of years. Touching these stones gives a tangible sense of geological time rarely felt at lower elevations.
Summer Wildflowers
From June to August, alpine meadows around the lake bloom with rhododendrons and yellow Meconopsis. During one summer visit, I met a group of Tibetan children weaving wildflowers into wreaths. They laughed and handed one to me—a small, unforgettable moment that stayed longer than any photograph.

Tibetan Culture Around the Lake
Prayer Flags and Mani Stones
Colorful prayer flags line parts of the lakeshore, fluttering constantly in the plateau wind. Nearby Mani stones, carved with the six-syllable Buddhist mantra, reflect the deep spiritual connection locals maintain with the land.
I once watched an elderly Tibetan Ama (grandmother) slowly circling the lake clockwise, murmuring prayers. Her presence felt as timeless as the lake itself.
Local Legends
Locals say Red Sea Lake was once an important gold-mining site. According to legend, gold sand at the lake bottom could cure illness. While mining is long gone, the stories add another layer of mystery to Hong Haizi.

Things to Do at Red Sea Lake
Photography
- Best viewpoints:
- East shore for Bijia Mountain reflections
- Southwest peninsula for creative wide-angle shots

During one hike, I met a French backpacker. He shared bread, I shared highland barley cake. We toasted quietly to the mountains.
For those with energy, a short hike northwest leads to visible glacial moraines and cirques.
Food and Picnic
There are no restaurants at the lake, so bring your own food or prepare meals in Xinduqiao.
- Tsampa (roasted barley flour)
- Air-dried yak jerky
- Yak butter tea (ask for less butter if new to it)
A simple picnic by the lake, with snow peaks as a backdrop, often becomes the highlight of the day.
