[IMAGE:flat-design-vietnam-cycling-hai-van-pass-coastal-esim-navigation-illustration]
Vietnam’s north-to-south geography makes it one of the world’s great cycling destinations — a 1,600km spine from Hanoi to Ho Chi Minh City, with options ranging from coastal Highway 1 to the mountain Ho Chi Minh Road through the Central Highlands. Coverage along these routes reflects Vietnam’s extensive coastal network.
### Main Vietnam Cycling Routes
**Hai Van Pass** (between Hue and Da Nang, 21km):
One of Southeast Asia’s most famous mountain passes — the wall between Vietnam’s north and south. Good 3G–4G throughout the pass road.
**Coastal Highway 1** (full-length north-south option):
The main coastal road has good 3G–4G coverage for the majority of its length. Urban sections (Hanoi, Da Nang, Nha Trang, HCMC): excellent 4G.
**Ho Chi Minh Road** (western inland option):
The wartime supply route through the Truong Son mountains. More remote; 2G–3G in many sections. The greater adventure; less coverage.
**Red River Delta** (north Vietnam plains cycling):
Good coverage throughout the flat agricultural delta region around Hanoi.
**Mekong Delta** (south Vietnam):
Good 3G–4G throughout the densely-populated delta region. Canal-side roads well-covered.

### Coverage at Hai Van Pass
The Hai Van Pass is Vietnam’s iconic road — cloud-covered summit, ocean views in both directions. Coverage: reasonable 3G–4G at the summit and throughout the pass road. Enough for uploading the obligatory summit photo.
