1. Explore Phong Nha-Ke Bang National Park Caves
Venturing into Phong Nha-Ke Bang National Park offers an unparalleled opportunity to discover some of the world's most spectacular cave systems. Paradise Cave mesmerizes visitors with its colossal chambers and intricate stalactite and stalagmite formations, resembling an 'underground palace'. Dark Cave provides an adventurous experience, inviting visitors to zipline across a river, swim into the cave entrance, and navigate through dark passages to experience a mud bath. Phong Nha Cave is unique, primarily explored by boat along its underground river, showcasing impressive rock formations. It is recommended to choose a full-day tour that often combines two of these popular caves to maximize the experience.
Cost: Entrance fees vary per cave. Paradise Cave costs 250,000 VND per adult, with an optional electric car ride for 25,000 VND (round trip per person) or 100,000 VND for a 4-seat buggy (round trip). Phong Nha Cave requires a boat fee of 550,000 VND per boat (up to 12 people), plus an individual entry fee of 150,000 VND per adult. Dark Cave's full-service combo ticket (including zipline, kayaking, and mud bath) is 450,000 VND per adult. Tour packages combining two caves typically range from $55-$89 USD (approximately 1,375,000 - 2,225,000 VND) and often include transport, guide, and lunch.
Transport: Phong Nha-Ke Bang National Park is approximately 45-70 km northwest of Dong Hoi. The most convenient way to visit is by booking a tour, which usually includes hotel pick-up and drop-off from Dong Hoi. Alternatively, a taxi ride costs about 600,000-800,000 VND one-way. Renting a motorbike for around 100,000-150,000 VND per day is another option, but international tourists are generally not recommended to drive motorbikes in Vietnam without proper licensing and experience. Local buses (Route B4) are available from Dong Hoi to Phong Nha-Ke Bang for about 35,000 VND per person.
