Phong Nha-Kẻ Bàng is a UNESCO World Heritage property inscribed in 2003 for its exceptional karst landscape and cave systems. (whc.unesco.org)) Paradise Cave (Hang Thiên Đường) was first scientifically mapped by the British Caving Research Association in 2005 and the cave system explored to about 31.4 km, making it one of Asia’s longest dry caves. (phongnhadiscovery.com)) Access to Son Doong, the world’s largest cave inside the Phong Nha area, is strictly limited—operators cap visits at roughly 1,000 people per year and run pre-scheduled multi‑day expeditions. (sondoongcave.info)) Official Son Doong expeditions are sold through licensed outfitters such as Oxalis and typically cost in the ballpark of US$3,000 per person for a multi‑day trip, with seasons concentrated in the dry months. (oxalisadventure.com)) Quảng Bình province — the gateway for Phong Nha — recorded about 5.2 million visitors in 2024 as it pursues a VNĐ1,253 billion (roughly US$49 million) development plan to expand nine destinations and 11 new tourist routes through 2030. (en.vneconomy.vn)) Pu Luong Nature Reserve in Thanh Hóa was established in 1999 and covers about 17,662 hectares, two‑thirds of which is tropical forest including strictly protected and ecological restoration zones. (en.nbca.gov.vn)) Pu Luong sits roughly 130–180 km southwest of Hanoi (about a 3–4 hour drive), is served by clusters of Thai and Mường villages such as Don, Hieu and Kho Muong offering community homestays and eco‑lodges, and homestay rates commonly range from ~250,000–600,000 VND per night.
