Spend some time exploring Phong Nha town (Sơn Trạch village) itself. While small, it serves as the main hub for visitors to the national park. Stroll along the main road flanking the Son River, enjoy the views of the karst mountains rising dramatically around the town, and check out the local restaurants and cafes.
The town has a relaxed, traveller-friendly atmosphere. It's the base for booking cave tours, renting motorbikes or bicycles, and arranging boat trips. Enjoying the laid-back vibe of Phong Nha town is part of the experience.
