Guizhou: The World's Largest Eye — 5 Days
A telescope that listens to the edge of the universe
In a natural sinkhole in the mountains of Guizhou, China built something bigger than 30 football fields: the Five-hundred-meter Aperture Spherical Telescope (FAST).
It’s the largest and most sensitive radio telescope in the world. It has already discovered hundreds of new pulsars and detects signals that traveled for billions of years. Nothing else built by humans listens this deeply.
What makes this trip unique
- FAST — see the world’s largest single-dish radio telescope up close
- Karst landscape — the surreal limestone scenery that made the site possible
- Miao villages — traditional ethnic culture, largely unchanged
- Big science — understand China’s growing role in fundamental astronomy
Why few foreigners come here
Guizhou is remote, mountainous, and not on most tourist routes. That’s exactly why it’s special. You’ll see a China that the package tours skip — wild, rural, and home to one of humanity’s most ambitious scientific instruments.

Frequently asked questions
What is FAST and why is it important? +
FAST (Five-hundred-meter Aperture Spherical Telescope) is the world's largest and most sensitive single-dish radio telescope, completed in 2016. It detects pulsars, fast radio bursts, and potential extraterrestrial signals. Its sensitivity exceeds the Arecibo telescope that collapsed in 2020.
How close can we get to FAST? +
All electronic devices must be powered off within 5km (to prevent radio interference). You view the telescope from a dedicated observation deck on the mountain above. The scale is hard to convey until you see it.
Is Guizhou worth visiting beyond the telescope? +
Absolutely. Guizhou has some of China's most dramatic karst landscapes, extensive cave systems, and ethnic-minority villages (Miao, Dong, Bouyei) where traditional life continues. It's far less touristy than the east coast.
Is this tour suitable for children? +
Yes for ages 10+. The telescope fascinates kids interested in space, and the caves and villages add adventure. Younger children may find the travel distances long.
