How serious is landslide risk in Vietnam in 2026?

Hải Vân Mountain between Hue and Da Nang is a documented landslide hotspot on the north–south highway and railway. Weathered granite slopes, steep cuts, and intense central-coast rain trigger shallow slides, rockfall, and debris flows that close or slow traffic: Living in Da Nang and Living in Hue. Tunnel alternatives help, but surface pass travel still needs storm caution.

Central Highlands corridors toward Da Lat and Kon Tum-style mountain districts see the same rain-triggered pattern on national and provincial roads: Highland climate and Living in Da Lat. Northern mountain routes around Sa Pa and Ha Giang add fog and cold to the same slope risk: Fog. Road authorities publicly track hundreds of vulnerable points across northern and central mountain networks during wet seasons.

Do not romanticise a cheap hillside house above a fresh cut slope or a leaking retaining wall. Ask neighbours about past road closures, walk the access after heavy rain, and keep an alternate route for airport or hospital trips. Typhoon weeks stack wind, flood, and landslide alerts together: Typhoon risk and Flood risk.

Delay non-essential mountain rides when NCHMF and local civil defence warn of prolonged rain. Scooter tourism on Hải Vân during peak wet months is a visibility and debris gamble, not a neutral photo stop: Wind and Outdoor recreation.
