Khayer is situated off the normal beaten trails of the Ghorepani trek and has to be done under canvas. The destination is a high mountain lake situated to the north of Annapurna South. The lake is popular with pilgrims at certain times of the year and the trek up provides some truly spectacular mountain views.
The area is extremely secluded hidden behind the massif of Annapurna. You trek a pattern of undulating ridges and if you are considering this particular trek it is best done in spring when there is an abundance of flowers. A lot of the trek up to the lake takes you through colorful rhododendron forest, which is also in bloom in spring.

The area holds two big festivals every year in the months of March and April and July and August when all the locals gather together on the top of the ridge (Khopra Hill).In the first case the locals slay a Yak and drink the blood hot as it is believed to be a cure for all illness.

On the occasion of sacred-thread replacement day (Full Moon of August) people believe that all their wishes will be fulfilled after a visit to the lake. People also believe that if they touch the water of Khayer Lake they will be granted salvation after death. Likewise married women who have yet to conceive visit the lake to ask for the fertility of their wombs.
