Tien Son Cave Tickets & Tours & Informataion April 2025

The Basics

Tien Son Cave, also known as the "Heavenly Son Cave," is relatively accessible compared to other caves in the Phong Nha region. The cave is approximately 2 kilometers (1.2 miles) from the main entrance of Phong Nha Cave, which is known for its large scale and boat tours. Tien Son Cave, in contrast, is more intimate and can be explored on foot. Visitors will encounter various formations such as massive stalactites, crystal-clear ponds, and an array of fascinating mineral structures. A short walk through the cave's main chamber leads to a stunning underground lake, adding to the allure of this hidden gem.

Things to Know Before You Go

Before visiting Tien Son Cave, be aware that the cave can be physically demanding, especially if you are exploring on foot. The hike to the cave involves climbing some steep terrain, so be sure to wear comfortable footwear, preferably hiking boots, to ensure a safe journey. Also, pack light but bring essentials such as water, a flashlight, and a camera. The cave is well-lit in most areas, but some parts can be dim, so extra light is handy. It’s also important to carry insect repellent as the surrounding jungle can have mosquitoes.

How to Get There

Tien Son Cave is located around 8 kilometers (5 miles) from Dong Hoi city center, making it easily accessible by car or motorbike. The quickest way to reach the cave is by driving from Dong Hoi to the Phong Nha-Kẻ Bàng National Park. From the park entrance, you’ll need to trek approximately 2 kilometers to reach the cave. If you prefer not to drive, you can also book a tour from Dong Hoi, which typically includes transportation to and from the cave, making the journey hassle-free. Tours often offer expert guides to enhance the experience and ensure you don’t miss any of the cave’s highlights.

When to Get There

The best time to visit Tien Son Cave is during the dry season, which lasts from February to August. During this period, the weather is cooler and more suitable for outdoor activities such as hiking and cave exploration. The rainy season from September to January can lead to muddy and slippery trails, making the hike to the cave more challenging. For the most enjoyable experience, visit during the dry months to avoid disruptions from the weather and to make the most of your time exploring this beautiful cave.

Day Trips from Dong Hoi

Tien Son Cave is an ideal destination for a day trip from Dong Hoi. Many local travel agencies offer guided tours that include a visit to Tien Son Cave as part of a larger package, often combined with a stop at the nearby Phong Nha Cave or other scenic spots in the area. These tours typically start in the morning and return in the late afternoon, allowing you to experience the cave and its natural beauty without requiring an overnight stay. If you prefer a self-guided experience, you can take a motorbike or taxi directly to the cave entrance and enjoy a leisurely exploration at your own pace.
