The Scots undertook a similar trip to the town of Spala before taking part in last year's Rugby World Cup in Australia.

Williams wants the trip, starting on July 27, to be an annual event.

He said: The facilities offered are second to none and the trip gives the players an intensive period to work not only on the physical aspect of their game but also concentrate on every other aspect of being a professional sportsman.

Injured internationals Andrew Mower, Euan Murray, Tom Philip and Simon Taylor will not travel.
