Hill tribes in northern Thailand take part in a festival featuring a giant swing soaring over a mountainside.

The native Akha people from more than 30 different tribal villages gathered in the Mae Sarong district of Chiang Rai for the event.

Festivities featured hill tribe costumes, shows, and activities which showed their daily life and culture.

The highlight was the 'Swing Ceremony' in which the Akha people fly through the misty mountain air on 30ft high handmade swings in order to show their thanks to the Goddess of Abundance and pray for good crop yields.

The ceremony was also accompanied by celebrations and dancing.
