What is the maximum weight limit for the Zipline at Chay River - Dark Cave in kg?

Chay River – Dark Cave is located in the core zone of Phong Nha – Ke Bang National Park, in Son Trach Commune, Bo Trach District, Quang Binh. This is one of the most prominent tourist destinations combining cave exploration and adventure activities in the region. The Zipline system here was put into operation in 2014, with the main zipline being about 400 meters long. This line takes visitors from the observation deck across the clear blue Chay River to near the entrance of Dark Cave. In addition, there is a shorter Zipline allowing visitors to drop themselves into the river for a swim.

The system is designed with dual cables and safety-compliant equipment, offering the sensation of gliding through the wind at speeds of around 40–45 km/h. From above, you will have a panoramic view of the limestone mountains and forests, the emerald river, and the characteristic wild nature of Phong Nha.

When participating in the zipline activity at Chay River - Dark Cave, visitors need to note the weight limits to ensure absolute safety. According to current regulations of the tourist area, the requirements for participating in the Zipline at Chay River – Dark Cave are:

• Minimum weight: 40 kg

• Maximum weight: 90 kg

• Minimum height: 1.3 m or taller (applicable to eligible adults and teenagers)

This is a mandatory regulation framework. Persons weighing under 40 kg or over 90 kg will not be allowed to participate to ensure the safety of the cable system, pulleys, and protective equipment. In addition, pregnant women, people with cardiovascular conditions, blood pressure issues, or joint problems should carefully consider and refrain from participating. Before starting the journey of "flying" across the blue river, you will undergo a health check, sign a commitment, and be fully equipped with safety harnesses and helmets by professional staff at the tourist site.

After meeting the weight and height requirements, you need to prepare thoroughly so that your zipline trip goes smoothly, safely, and completely:

• Light clothing: Wear comfortable clothes, preferably long pants and sneakers for easy movement. Women should wear bikinis and men swim trunks if combining river swimming or mud bathing in Dark Cave.
• Filming and photography gear: If you want to capture the moment of gliding on the zipline, bring a GoPro or a selfie stick, but don't forget to use a waterproof bag to protect your equipment.
• Weather check: The ideal time to try ziplining is from April to September, when the sky is blue, the water is clear, and the scenery is at its peak beauty. Avoid the rainy and stormy season (September to March) as activities may be interrupted.
• Eat before playing: Adventure activities consume a lot of energy, so have a light snack to have the energy to unleash yourself.

In addition, if you are concerned about safety, rest assured that the zipline system here is designed and constructed by experts, meeting international standards. Tour guides are always on hand to assist, from fitting protective gear to instructing proper sliding techniques.

If you choose the zipline route that ends with a drop into the river, the sensation of speeding along and then splashing into the cool water will delight many to the point of wanting to play again. However, in reality, quite a few visitors give up after just 40 seconds, because the height and speed of the game are truly not gentle at all.

After conquering the zipline, you can continue exploring Dark Cave with activities such as natural mud bathing, kayaking, and enjoying a lunch with rustic dishes like grilled chicken, stream fish, and sticky rice at the riverside restaurant. These full experiences will make your trip even more memorable.
