Tourists flock to Doi Inthanon as park gets 8th hoarfrost this winter

Unlike regular frost, where water vapour first condenses as liquid water on the object and then freezes, hoarfrost forms directly from water vapour into ice crystals without going through the liquid phase.

Kriangkrai Chaipiset, chief of the Doi Inthanon National Park, said the lowest temperature on Sunday morning was measured at the front of the Kew Mae Pan nature trail.

A lot of tourists went to the Kew Mae Pan viewpoint to wait for sunrise. Most of them donned hats, gloves and scarves because of the chill.

Kriangkrai said park officials were deployed to watch over tourists on Doi Inthanon around the clock on New Year’s Eve. The park has installed 15 security cameras for surveillance.
