Day 1: Canh Chao sinkhole - Ho Thang Hen

It's not easy to climb down, but you'll see the magic of water for millions of years of absorption and erosion. If you look from above, you can see an entire mountain range that seems to be gouged out by the creator with a giant hole in the middle. If you don't look up at the bottom of the Sinkhole, you'll see a magical dome of the sky. Around the Sinkhole are steep cliffs with moss and grass clinging to lush green growth. Beneath the Sinkhole are many types of trees from woody to grassy stems forming a luxuriant forest as if standing in a miniature version of Son Doong cave (Quang Binh).

A lunch right in the sinkhole is probably an unforgettable experience for anyone when joining the journey. Simple but nutritious dishes have been prepared. While having lunch, chatting and listening to the stories of the guides in the cool and majestic space of the sinkhole, feel small in front of nature.


The first day of exploration ends with a trekking trip back to Thang Hen Lake, exploring this beautiful but also mysterious lake.
