Can you swim in the river of Five colors?

The River of Five Colors is a geological phenomenon located in the Jiuzhaigou National Park in Sichuan Province, China. This river earned its colorful name from its five distinct colored sections – blue, green, yellow, black, and white. The colors come from the natural minerals dissolved in the water and the river bed’s rock composition. Many visitors are awed by the river’s beauty and some may be tempted to swim in its vibrant waters. However, regulations prohibit swimming for safety and environmental reasons.

Overview of the River of Five Colors

The River of Five Colors winds through Jiuzhaigou Valley, traversing 9.3 miles through forests, lakes, and waterfalls. The five distinct sections each exhibit a different hue:

  • Blue – Caused by calcium carbonate in the water
  • Green – Due to algae on the riverbed
  • Yellow – From calcium and carbonate sediments
  • Black – From plant matter and algae on the lake bed
  • White – Due to frothy foams and waves over travertine shoals

The water transitions from one vibrant color to the next along the river. The striking color combinations make the River of Five Colors a mesmerizing sight. The natural beauty also draws millions of visitors annually to Jiuzhaigou Valley.

Reasons Swimming is Prohibited

While the multi-hued river may look appealing for a swim, regulations strictly prohibit entering the water. Here are the main reasons why visitors cannot swim in the River of Five Colors:

Preservation of Natural Environment

Jiuzhaigou Valley is a UNESCO World Heritage Site and national park. Authorities enforce measures to protect the vulnerable natural ecosystem. Human contact with the water can contaminate the river, disturb sediments, and damage the environment. Swimming also disrupts native wildlife habitats along the river’s shores.

Water Hazards and Safety

Despite its beauty, dangers lurk beneath the River of Five Colors’ surface. Strong currents and undertows can catch swimmers off guard and carry them away. The water temperatures remain near freezing year-round, risking hypothermia. Sudden dropoffs, slippery rocks, and hidden obstructions also endanger swimmers’ safety. Several fatalities have occurred from people disregarding the no swimming rules.

Overcrowding and Access Issues

Mass tourism at sites like the River of Five Colors has damaging effects. Unregulated swimming would only heighten problems with overcrowding, pollution, and soil erosion along the river banks. Prohibiting swimming helps manage visitors and maintain sustainable access to this natural wonder.

Section Length (miles) Color Cause of Color
Blue 2.1 Blue Calcium carbonate
Green 1.3 Green Algae
Yellow 1.7 Yellow Calcium and carbonate sediments
Black 1.1 Black Plant matter and algae
White 3.1 White Foams and waves over travertine

This table provides details on each colored section of the River of Five Colors, including its length, hue, and what minerals or sediments cause the color.

Enjoying the River Without Swimming

While swimming is prohibited, visitors can still enjoy the River of Five Colors through controlled activities:

  • Photography – Capture stunning photos of the multicolored water from designated lookouts and platforms.
  • Boating – Float down parts of the river on tour boats with guides.
  • Hiking – Trek along maintained trails with river views.
  • Eco-tours – Join educational tours led by park rangers.

These regulated activities allow visitors to appreciate the river’s beauty safely. By following park rules, people can help preserve the River of Five Colors for future generations.

The Importance of Preserving the River

The River of Five Colors is a natural wonder of geological processes and aquatic ecosystems at work. Preserving this site is important for scientific, economic, and cultural reasons:

Scientific Value

The river provides opportunities to study unique geological and ecological processes that produce its distinctive multi-hued waters.

Tourism Revenue

Jiuzhaigou Valley generates over $28 million annually in tourism revenue from visitors who come to see the river and surrounding nature.

Cultural Significance

The river holds cultural and spiritual importance for local Tibetan and Qiang minority groups.

Prohibiting swimming and human contact protects the integrity of this natural wonder for research, business, and cultural heritage.


The River of Five Colors is a breathtaking natural site, but its fragile ecosystem requires environmental protections like swimming prohibitions. Visitors can still immerse themselves in the river’s beauty through guided activities. By upholding park rules, we ensure this geological wonder and important ecosystem remains preserved.

Though tempting for a swim, respecting regulations at sites like the River of Five Colors demonstrates our collective responsibility to protect vulnerable natural environments. When we preserve nature responsibly, these unique sites can continue amazing and educating visitors for generations to come through controlled access. What may require self-restraint today pays dividends for the future as sustainable tourism and conservation ultimately allow more people appreciate the world’s natural wonders.
