— Overview

Why this route.

Chieu Lau Thi — Kieu Lieu Ti on some maps — is the highest ground we reach at 2,402 m. You climb from Ta Su Choong, sleep at the mountain shelter near 2,000 m, and walk a short pre-dawn section to the summit ridge. Everything on the route serves that hour when cloud fills the valleys below. Choose this if a 02:30 departure from town is not for you but you still want the summit dawn. Choose the one-day sunrise ridge if your dates are tight and you can handle a single hard day without a shelter night.

— Trip highlights
  • Shelter night at 2,000 m — no 02:30 departure from Hoang Su Phi town
  • Short pre-dawn walk to the 2,402 m summit from high camp
  • Cloud sea on the eastern ridge when valley inversions align
  • Cardamom-forest descent with hot breakfast and picnic lunch

— Good to know

Before you walk.

  • Shelter sits near 2,000 m on the Ta Su Choong approach — inside temperature often 2 – 5 °C from November to March.
  • Guide field note: pre-dawn walk from shelter to the 2,402 m crest is 20 – 30 minutes; if cloud fills the valleys, guides wait at the marked standing lines rather than the windiest summit knob.
  • Choose the one-day sunrise ridge if your dates allow only a single calendar day.
  • Main bag stays in Hoang Su Phi with our driver — daypack only to the shelter.
  • No departures June – September — storm season on Tay Con Linh.

— FAQ

Common questions.

  • Q · 01

    Is altitude a concern?

    At 2,402 m, acute altitude sickness is unlikely for healthy adults. Drink steadily on Day 1 and dress for cold at the shelter.

  • Q · 02

    How cold is the shelter?

    Often 2–5 °C inside in shoulder season. Sleeping bag provided; bring thermals and wear them inside the bag if you run cold.

  • Q · 03

    What if there is no cloud sea?

    Still worth the walk — ridge views, alpenglow and westward terrace country reward the climb even when valleys stay clear.

  • Q · 04

    How does this differ from the one-day sunrise route?

    Same summit. This walk sleeps at the shelter and reaches the ridge after a short pre-dawn walk from high camp — no 02:30 departure from town.

  • Q · 05

    Where does my main bag go?

    It stays in Hoang Su Phi with our driver. You carry only a daypack to the shelter.

  • Q · 06

    Is there phone signal at the shelter?

    No reliable signal above 2,000 m. Your guide carries emergency contact protocol.

  • Q · 07

    What is the shelter like?

    Wooden bunks, shared room, sleeping bags and mats, squat toilet outside, wood stove in the evening.

  • Q · 08

    Do you run this in summer?

    No — June through September is storm season on Tay Con Linh.
