From the forest-based retreat experience at Blue Diamond Retreat, travelers can extend their journey with outdoor activities at Ozo Park, a popular destination for exploring forest landscapes and natural streams.
Ozo Park spans approximately 5 hectares and is situated adjacent to the primary forest of Phong Nha – Ke Bang National Park. The area is shaded year-round by large forest trees and surrounded by the clear waters of Ozo Stream.
The park features various experience zones, including a continuous tree-top obstacle course among the forest canopy, zipline activities, and guided forest exploration tours. All activities are designed to be gentle and accessible, focusing on enjoyment rather than challenges. This makes Ozo Park a suitable destination for groups, families, and young travelers looking to spend a relaxing and meaningful day immersed in the green nature of Phong Nha.
Family-friendly activities at Ozo Park for children
One of the highlights of Ozo Park is its series of seven connected tree-top games set beneath the cool forest canopy. Participants wear safety harnesses and move through a range of light challenges such as hanging wooden bridges, balance ropes, horizontal climbing nets, and separate wooden steps.
The height of the course is carefully designed to create a sense of adventure without causing stress or fear. Children can take their time at their own pace, while parents can walk alongside them, offering support and encouragement. This turns each challenge into a shared experience and a meaningful moment of connection between family members.
After leaving the tree-top games area, the experience continues with a gentle zipline ride through the forest canopy. Ozo Park has a separate zipline section designed specifically for young children, with appropriate length and speed to ensure safety and comfort. Staff members are always present to guide each turn carefully, helping children feel more confident, especially if it is their first time trying a high-level activity.

When reaching Ozo Stream, the atmosphere changes into a more open and relaxing space. The water is clear and cool, with many shallow areas near the banks where children can safely play.
Families can enjoy kayaking or stand-up paddleboarding on the calm sections of the stream, moving slowly while taking time to rest and relax. This is an area where many families choose to stay longer, swimming and playing at their own pace.
In another forest area of Ozo Park, a 999-meter wooden walkway leads visitors through the tree canopy, allowing them to observe the natural ecosystem without disturbing the vegetation. Along this path, young travelers can enjoy an easy forest walk and learn about the tropical environment, where a variety of plants can be seen, including shrubs, tall trees, and wildflowers.
Ozo Park is not only suitable for a short visit but is also designed to fit easily into different travel itineraries in Phong Nha. Many families choose a day pass and spend several hours enjoying the forest, the stream, and light outdoor activities before continuing their journey to other nearby attractions.
Services and facilities at Ozo Park
Ozo Park places a strong focus on services and facilities, allowing families to comfortably spend a full day in the forest. After a morning of tree-top activities, kayaking, or ziplining, the Green Forest Restaurant, located inside the park, is a popular stop for families to recharge.
The menu mainly features local specialties such as free-range chicken, stream fish, and freshly grilled meats. Meals are served hot and attractively presented on traditional bamboo trays, accompanied by fresh vegetables, sticky rice, and seasonal fruits.
After enjoying the activities and swimming in the stream, visitors can use the shower and changing facilities and rest at the free forest shelters within the park. In addition, shuttle bus services from Phong Nha and Dong Hoi make it easier and more convenient to reach Ozo Park, especially for travelers exploring Phong Nha independently.
Location and best time to visit Ozo Park
Ozo Park is located in Phong Nha, within the buffer zone of Phong Nha – Ke Bang National Park. The park reflects the typical features of a tropical forest ecosystem, with dense greenery, natural streams, and a cool and refreshing atmosphere.
One of the advantages of Ozo Park is its location along Victory Road 20, the main tourist route in Phong Nha. This makes it easy to combine a visit to the park with other nearby attractions. Travelers can explore Phong Nha Cave, Botanical Garden, Commander Cave Museum, Paradise Cave, or Bong Lai Valley, and then spend half a day enjoying outdoor activities or even stay overnight for camping at Ozo Park.
Travelers departing from Dong Hoi or Phong Nha can book Ozo Park’s shuttle bus service, with the transfer cost included in the ticket price. For families traveling independently in Quang Tri, private car rentals or taxis are also convenient options for reaching the park.
The best time to visit Ozo Park is during the dry season, from February to August. In the early months of the year, Phong Nha transitions from the cool days of late winter into a warm spring, with gentle sunshine, lush green forests, and clear, refreshing streams. From late spring through summer is the peak travel season, when tree-top activities, zipline experiences, and stream swimming are at their most active and enjoyable.
From September to November, Phong Nha may experience short periods of rain, but on days with favorable weather, Ozo Park still operates as usual. From December to February is the cooler season, with cloudy skies and fewer visitors. Visiting Ozo Park during winter offers a slower and more peaceful atmosphere, suitable for travelers who prefer a quiet nature experience.
