Before diving into photo tips, let's learn a bit about the zipline at Chay River - Dark Cave. Opened in 2014, Chay River zipline is one of the premier adventure activities in Quang Binh. Extending around 400m, you will be suspended on a cable, soaring across the turquoise river and admiring the Phong Nha mountains from above. There are two main options:

- Zipline from the observation deck to the entrance of Dark Cave: Ideal for capturing panoramic nature photos.
- Zipline from the boat station into the middle of the river: A bigger thrill as you plunge into the cool water.
The zipline system is modernly equipped, ensuring maximum safety, designed for participants weighing between 40kg and no more than 90kg, with a minimum height of 1.3m. The ideal time to participate and take photos is from April to July, when the weather is dry, natural light is beautiful, and the river water is crystal clear.
