What to see in Phia Oac National Park

Phia Oac Peak is the highest point in the national park, offering breathtaking panoramic views of the surrounding landscape. At over 1,900 meters above sea level, the peak is often shrouded in mist, creating a mystical atmosphere. The trek to the summit is a rewarding experience for hikers, with the path winding through dense forests and past cascading streams. On clear days, the view from the top stretches out across the rugged mountain ranges, making it a photographer’s paradise.

2. Ruins of a French colonial Villa

Hidden deep within the park are the ruins of a French colonial villa, a relic from Vietnam’s colonial past. Known locally as the Red Villa, these ruins date back to the French colonial period when the villa was likely used as a retreat to escape the summer heat of Hanoi. Today, the crumbling walls and overgrown structures stand as a silent testament to a bygone era, offering visitors a glimpse into the history that shaped the region. The site is both haunting and fascinating, providing a stark contrast to the natural beauty of the surrounding landscape.

3. Phia Oac tea planations

The Phia Oac tea plantations are a must-visit for those interested in Vietnam’s agricultural heritage. These lush tea fields, spread over 30 hectares, are perched on the hillsides of the park, offering stunning views of the surrounding mountains. Visitors are welcome to wander through the fields, take photos, and even pick tea leaves with permission from the local farmers. The plantation also has a small restaurant where you can sample dishes made with Shan Tuyet tea leaves, accompanied by special cakes that pair perfectly with the farm’s many delicious teas.

4. Phan Thanh Grass Hills

The Phan Thanh Grass Hills are a series of expansive grass fields located on the rolling hills within the park. These open fields provide some of the best views in Phia Oac, particularly at sunset when the light casts a golden hue over the landscape. The grass hills are also a popular spot for camping, offering a tranquil setting to enjoy the natural beauty of the park. The wide-open spaces and panoramic vistas make this a perfect spot for a peaceful retreat into nature.

5. The Hanging rock

This natural rock formation juts out from the hillside, creating a perfect perch for taking photos against the backdrop of the park’s stunning mountain scenery. The site has become a favorite among visitors looking for that perfect Instagram shot, but it also offers a unique perspective on the park’s diverse geological landscape.

6. Thanh Cong Bamboo Forest

Located far from the park’s other attractions, this bamboo forest offers a tranquil escape into nature. The path through the forest is flanked by tall, straight rows of bamboo, creating a natural tunnel that is both peaceful and visually striking.

Accommodation around Phia Oac National Park

If you’re planning a journey from the Ban Gioc Waterfall in the northeast to Bao Lac or Ha Giang in the west (or visa versa), Phia Oac National Park makes for a perfect midway stop. However, it’s challenging to combine a visit to the park with a long drive in a single day, so staying overnight is a practical and enjoyable option.

Cao Bang City, the closest urban center, is still a 1.5 to 2-hour drive from the park, and there are no large towns nearby. However, a few homestays are available around the park, offering basic yet comfortable accommodations that allow for a more authentic, local experience. These homestays are not only a place to sleep but also a good option for meals, as restaurants are scarce in this remote area.

Best travel time

Autumn and Spring – The Ideal Seasons

The best time to visit Phia Oac National Park is during autumn (September to November) and spring (March to May). These months offer the most pleasant weather, with mild temperatures and minimal rainfall, making it perfect for hiking and exploring the park’s natural beauty. The autumn months are particularly beautiful, with the landscape adorned in golden hues, while spring brings fresh greenery and blooming flowers.

Summer – The Greenest Season

During the summer months (June to August), Phia Oac National Park is at its greenest, with lush vegetation covering the mountains and valleys. However, this season also brings more rain, which can make some trails slippery and difficult to navigate. The increased humidity can be a challenge for some travelers, but the vibrant landscapes and fewer crowds can make it a rewarding time to visit.

Winter – A Chance of Frost

Winter (December to February) in Phia Oac National Park is unique, as it’s one of the few places in Vietnam where you might see frost or even a dusting of snow on the higher peaks. The temperatures can drop significantly, especially at night, so if you’re visiting during this time, be sure to pack warm clothing. The park takes on a serene and mystical atmosphere during winter, with misty mornings and crisp air, offering a different but equally enchanting experience.

How to get there?

Visiting tips

Phia Oac National Park is a true off-the-beaten-track destination. Located in Cao Bang, which is already one of the less-traveled provinces in Vietnam, the park itself is remote from other popular sights. As a result, reaching the park is only possible by private transportation. Although it’s far from sights like Ban Gioc Waterfall, Phong Nam Valley, and Angel Eye Mountain, Phia Oac National Park makes a great stop for those traveling between the west of Cao Bang (towards Bao Lac) and further onto Ha Giang, or for those coming from Ha Giang and heading towards Cao Bang City or Ban Gioc.

Getting to Cao Bang City

Before reaching Phia Oac National Park, your first step is to get to Cao Bang City, the main hub for exploring the hidden gems of the province. Since Cao Bang lacks a train station or airport, your only option is to travel by road.

  • Sleeper Bus: These buses operate at night, allowing you to save daytime travel hours. They are a cost-effective option, but not everyone finds them comfortable for sleeping.
  • Limousine Vans: Offering more comfort and space than standard buses, these vans provide a smooth daytime journey, making them a popular choice for travelers.

From Cao Bang to Phia Oac National Park

Once you arrive in Cao Bang City, there are several options to reach Phia Oac National Park:

  • Driving Motorbike: For those seeking adventure, renting a motorbike in Cao Bang City is a popular option. The ride offers incredible views, but it’s important to have a valid license and experience in handling mountain roads.
  • Motorbike Tour: If you prefer not to drive yourself, a motorbike tour is a great alternative. You can ride on the back of a motorbike with an experienced local guide who knows the best routes and hidden spots.
  • Renting a Car with Driver: For more comfort, especially during the rainy season or colder months, renting a car with a driver is the best option. It provides protection from the elements and allows you to enjoy the scenery without the stress of navigating unfamiliar roads.
