Dry season (February to August) — more stable weather, easier cave access and clearer river conditions. The rainy season (September to January) can bring heavy rains, swollen rivers and temporary cave closures.

Tropical monsoon climate: hot, humid summers and a distinct rainy season. Average temperatures typically range from about 20°C to 35°C; heavy rains and typhoon influence are possible in late autumn and winter months.

Cave and park fees vary by site and tour operator. Day-access caves (Phong Nha, Paradise, Dark Cave) have per-person entrance and boat/guide fees; specialized expeditions (Son Doong) require permit fees and expensive multi-day guided packages booked well in advance. Most sites operate daily, but individual cave tours have scheduled departure times — check operators ahead of arrival.

Nearest airport: Dong Hoi (Phu Bai?) — actually, the correct nearest airport is Dong Hoi (Quang Binh) Airport (VDH), about 40–50 km from the park entrance. Road access from National Highway 1A and provincial roads; regular buses and private cars run from Dong Hoi and Hue. The North–South railway stops at Dong Hoi station. Final approaches to many caves use riverboat transfers from Phong Nha village. Note: some trails and cave entrances require moderate fitness; Son Doong and multi-day treks have strict physical requirements.

2–4 days for a focused visit to Phong Nha, Paradise Cave and Dark Cave; 4–7 days to add extended treks and Hang En; 7–10+ days (and months of advance planning) if aiming for a Son Doong expedition.

Light, breathable clothing, sturdy hiking shoes, waterproof jacket for rainy season, swimwear and quick-dry towel, headlamp or flashlight, insect repellent, sun protection (hat, sunscreen), small first-aid kit. For guided expeditions bring the specialist gear recommended by operators.
