1. Introduction to Tien Son Cave

Tien Son Cave was first found in 1935 by locals, though it wasn’t officially surveyed or opened to tourism until the 1990s. Its poetic name, “Tien Son” originates from a local myth about fairies descending from the heavens to bask in its serenity.

Geologically, Tien Son Cave stands as an extraordinary relic of the Earth’s distant past, having been shaped more than 400 million years ago through tectonic activity and erosion. While other caves in Quang Binh offer adventure and excitement, Tien Son invites visitors to admire its stillness, shimmering beauty and timeless charm. It is an ideal destination for those who appreciate geology, natural artistry, and peaceful landscapes.

1.1. Location of Tien Son Cave

Tien Son Cave is located in Phong Nha Town, Bo Trach District, Quang Binh Province, around 50 kilometers northwest of Dong Hoi City. Positioned inside the Phong Nha - Ke Bang National Park, it lies just a few dozen meters away from Phong Nha Cave, yet the two are geologically unlinked. This proximity yet separation highlights the region’s complex and multi-layered geological structure.

The cave sits at an elevation of about 200 meters above the Son River and stretches approximately 980 meters into the limestone mountains. From the Phong Nha boat station, visitors must make their way up 583 steps to access the cave.

The entrance fee is typically around VND 80,000 (USD 3) per person, with free admission for children under 1.3 meters and a 50% discount for seniors, covering entry and exploration inside the cave.

While some nearby caves, such as “Hang Toi” (Dark Cave), focus on adventurous activities like kayaking and ziplining, Tien Son Cave offers a different kind of experience.
