More than 1000 scouts from 18 countries have set up camp for the 2012 Blair Atholl jamborette.
For the next 10 days they will take part in a variety of activities and stay in a tented village.
Scouts from countries including South Africa, Brazil, Russia, and Wales are taking part in the event as well as survivors of the March 2011 Japanese tsunami, financially supported by scouts from Fife.
The camp, which runs for two weeks over the July school holidays, has a 66-year history and is staffed entirely by adult volunteers from Scotland and abroad.
Activities at the Blair Atholl camp this year include hikes, mountain and river rescue training, Canadian American craftwork, and an interactive refugee experience to highlight awareness of global development issues.
After the camp, 200 families across Scotland will welcome scouts from visiting countries into their homes for up to five days' cultural exchange.
Callum Farquhar, a Dunfermline-based scout leader said: "Blair Atholl is such a unique and enriching experience for both the scouts attending and the adult volunteers who make it possible.
"The spirit of international friendship and profound cultural exchange that takes place amongst the participants is inspiring to see. This year is particularly poignant for us as we will be welcoming our friends from Japan who have bravely endured a devastating natural disaster.
"We are privileged to be in a position to help them and know that ours is just a small demonstration of the worldwide family and support that scouting can offer."
