Lachay, the oasis of mists

The hills of Lachay offer one of the favorite escape routes for the citizens of Lima. The hills are known as an 'oasis of mist' because the sea clouds reach there, flooding everything with mist and exuberant vegetation.

Lachay is actually a desert. However, as a result of the cloudy humidity, there is an immense number of plants, flowers, trees and, consequently, animals, birds and insects.

Due to all this wealth of flora and fauna, in 1977 the Lachay National Reserve was created, an area of ​​5,070 hectares protected by the Peruvian State.

This desert oasis is filled with vegetation during the months of May to October. On those days, many tourists (mainly from the city of Lima) come there to appreciate its beautiful landscapes and its endless greenery.

The authorities have established specific areas such as 'The Fox Circuit', the 'Partridge Circuit', the 'Tara Circuit'; where you can see these species of flora and fauna. In addition, the place has a beautiful viewpoint and a camping area. Likewise, the hills have puquiales (spring water source) product of the humidity condensed by the plants.

Lachay also has an interpretation center that investigates the flora and fauna of the place. Visits are allowed as long as people protect and preserve the natural beauty of the site.
