Before You Go
Book Hang En or Tu Lan with Oxalis at least 4–8 weeks ahead — spots sell out, especially Nov–Apr peak season.
Son Doong requires booking 12+ months in advance and costs ~$3,000 USD — contact Oxalis directly for permit allocation.
Train fitness before arrival: the Tu Lan and Hang En routes require 6–8 hours of hiking with river crossings.
Pack quick-dry clothing, a headlamp with spare batteries, and water shoes — Oxalis provides helmets and life jackets.
Purchase travel insurance that explicitly covers cave trekking and adventure activities before departure.
Good to Know
Oxalis Adventure is the only operator licensed for most caves here — don't book through third-party resellers, always go direct.
Hang En suits first-time cave campers (moderate fitness); Tu Lan is wetter and harder; Son Doong is a full expedition requiring peak fitness.
The best season is February to August — avoid September to November when flooding closes most cave systems entirely.
Carry your camera in a fully waterproof dry bag — every Tu Lan route involves full submersion multiple times.
Phong Nha Village is tiny — everything is walkable, and most lodges are within 500 m of the Oxalis office.
Local SIM cards work in the village but go completely dead once inside the national park — download offline maps beforehand.
Tipping porters and guides is expected and meaningful — 100,000–200,000 VND per day per guide is standard.
