Wrong...2d1n for the summit climb. At least 2 nights in Malaysia
actually.
Assuming u reach the day before the climb, u stay 1 night at the
nearby hostel. Early morning transfer on day 2 to Mt K. Start the
climb and reach the lodging at 3,000+m (I think so) and stay
overnight.
Before dawn, at around 3am, people will start scaling Mt K with
their guides in the dark. Bring headlights and torches, scarves,
food, drinking water etc... the rest can store in the lodging as u
would be going down for brunch. Then after the sunrise-summit
climb, return to lodging for brunch, and all the way down.
But I think you guys should stay longer la...no point gg there just
for the mountain. Try the WWR
