Meet your guide and driver in Sapa town in the morning. Transfer by car to the trekking starting point at the national park ranger station. Begin the trek through dense jungle, mountain trails and stream crossings inside Hoang Lien National Park. This route does not pass through villages, offering a pure nature trekking experience. Enjoy a simple picnic lunch in the forest. After lunch, continue trekking uphill through rocky slopes and changing vegetation as the altitude increases. In the late afternoon, arrive at the mountain base camp at around 2,800 metres. Rest, have dinner and stay overnight in a simple wooden mountain hut with your guide and porter team.
