While weather on Mt. Huangshan is not a problem, space can be. On May Day and National Day, legal holiday for the whole nation, swarms of people travel to Mt. Huangshan, putting severe strains on accommodation and restaurants. Tourists are advised to avoid Mt. Huangshan on these holidays.

Beautiful scenery all year round
The Yellow Mountains change their color and appearance with the alternation of seasons.
In spring blooming flowers decorate the slopes in a riot of color and fill the valleys with fragrance.
In summer you see verdurous peaks rising one upon another and near springs gurgling merrily.
Autumn dresses the mountains in red and purple, as maples are all blazing-red.
Winter turns them into a world of frost and ice with silver boughs and rocks everywhere.
