Walking distance vs road distance on Ha Giang treks

Google Maps and most transfer quotes measure road distance — sealed or dirt roads a vehicle can follow. Trekking distance is the walking line: terrace walls, forest paths, village tracks and ridge steps. Those two numbers are not interchangeable.

A support vehicle may cover tens of road kilometres while you walk a shorter trail. The reverse is also common: a short road gap hides a long walking day. Adding them together produces a false “trip km”.

This page explains the difference. It does not publish a new surveyed kilometre table. Programme pages show operational walking figures only where we already use them, and hide elevation gain until it is verified.

Walking km — the trail you cover on foot that day. This is the figure that belongs on a trek page.

Vehicle km — transfers between town, trailhead, overnight point or the next district. On the west-to-east journey, the Nam Ai to Lo Lo Chai recovery day is this kind of distance, not a walking day.

Approach or road-access km — a public map may list Ho Thau to Chieu Lau Thi as about 12 km of mountain road. That is access, not the lodge-to-summit walk. Origin-style road tables are useful for driving, not for selling a walking day.

Luggage transfer km — the motorbike line that moves your main bag between overnight points. It may share a road with the walk for a short section, or follow a different track entirely. It is not the guest walking distance.

On the Ban Luoc traverse Day 2 (Ho Thau → Nam Ai), walkers use a paved mountain-road link between village and terrace footpath sections. That paved link is part of the walking day — it does not mean the day is only road walking, and it does not mean the published 15 km walking figure is the same as Google driving distance between two pins.

The same day illustrates why three lines must stay separate: your feet follow the walking path (including the paved link), a support motorbike may carry your main bag on a related track, and a car pin-to-pin map measures something else again.

The long traverse programme publishes operational walking distances for each day on foot: Day 1 Ban Luoc → Ho Thau about 17 km; Day 2 Ho Thau → Nam Ai 15 km; Day 3 Nam Ai → Phin Ho approximately 17 km. Treat hours as planning ranges, not surveyed GPS truth.

Those numbers are walking km only. They are not added to vehicle recovery days, Hanoi transfer km, or pin-to-pin driving estimates. After Day 3 you finish on foot in Phin Ho, rest and eat, then move Phin Ho → Tan Quang by vehicle — that onward transfer is not part of the walking distance.

We do not publish the length in kilometres of the paved link on Day 2 until it is verified as a standalone figure. The field photo above shows that walkers use the link; the 15 km day total remains the operational walking figure.

Most consumer maps snap to the road network. Village paths on terrace walls and forest shelter lines are missing or incomplete. A pin-to-pin driving time from Hanoi or Ha Giang City tells you nothing about hours on foot above Nam Hong or on the karst.

Trail apps can be closer, but only if the recorded line matches our start, finish, overnight and walking section. A Chieu Lau Thi track that starts at the highest parking stairs is not the Ta Su Choong lodge programme. A Tay Con Linh camping track from Xà Phìn is not the Tung San forest-shelter line.

When public tracks disagree — Sky Path listings from about 3 km to 7 km — the usual cause is a different trailhead, a road section left on the GPS, or a loop versus a one-way. We do not average those into a fake official kilometre.

Peak altitudes that many independent sources agree on — Chieu Lau Thi at 2,402 m — can appear as highest point. That number is the summit marker, not the ascent from the lodge.

Operational walking ranges already used on a programme page may stay visible, labelled as operational, not surveyed. New kilometres from a single blog, an unlabeled elevation widget, or a mismatched GPX stay hidden.

We do not republish proprietary GPX or competitor maps. When an operator GPX exists, a future map can be labelled for what it is. Until then, map status stays unpublished.

Can I use Google Maps to estimate a Ha Giang trek?

Use it for Hanoi or Ha Giang City road timing only. Do not treat pin-to-pin driving km as the walk. Ask the programme page for the walking line.

Why don’t you publish elevation gain for every route?

Unlabeled elevation widgets often show prominence or cumulative GPS noise. Chieu Lau Thi’s widely copied ~1,597 m figure matches topographic prominence, not a day’s ascent. We hide gain until the number is verified for our line.

Is the 7-day west-to-east journey one continuous walk?

No. Terrace and plateau walking days are on foot. The western-to-eastern connection from Nam Ai toward Lo Lo Chai is a vehicle recovery day. Those kilometres are not added to walking km.
