The numbers of North American tourists rose by one third in the year to the end of June as Scotland geared up for a bumper year of events.

The latest official figures highlight the pulling power of major festivities such as Homecoming Scotland, and the celebrations around the anniversary of Bannockburn, which included a festival of Scottish clans, with many of those visiting travelling from across the Atlantic.

But the total number of visitors to Scotland dropped as fewer tourists from the rest of the UK ventured north in the early summer, according to the Office For National Statistics.

There were 510,000 visitors from America and Canada in 2013/14, against 385,000 the previous year, up 32 per cent.

The increase contributed to an 18 per cent overall rise in overseas holidaymakers, up from about 2.2 million to 2.6m, but domestic visitor numbers declined 7 per cent.

Taking domestic and overseas travellers together, the total number of visitors to Scotland dropped 4 per cent.

Spending by tourists from abroad increased from almost £1.5 billion to more than £1.6bn, while spending by UK visitors stayed the same.

Tourism Minister Fergus Ewing hailed the "impressive" North American figures and said the Year Of Homecoming campaign and the promotion of Scotland as the "home of golf" ahead of the Ryder Cup at Gleneagles had encouraged more visitors to enjoy Scotland and contributed to the overseas visitor boost.

He said: "The people at Scottish tourism's frontline, the staff in our hotels, cafes, restaurants and tourist attractions, are delivering results and providing a memorable experience for visitors from home and abroad."

Malcolm Roughead, chief executive of tourism agency VisitScotland, said: "2014 is the year we predicted Scotland would welcome the world. With a significant increase in overseas visitors, it seems we have done just that.

"This year has taken Scotland's profile and reputation to great heights and we are determined to make the most of this for the future.

"As we head into the 2015 Year Of Food And Drink and beyond, we will look to develop and build on all we have achieved. It is our turn to get out there and take Scotland to the world and ensure every single corner of the globe has heard of all we have to offer from innovative venues and hotels to breathtaking scenery and adventurous opportunities."

In recent years efforts to boost the lucrative American and Canadian market have included opening new air routes and marketing Scotland abroad.

Since 2012, development efforts have delivered more than 80 new routes to Scottish airports, including Chicago, Philadelphia, and Doha, the capital city of Qatar, with more announced for 2015.

In the last year alone, major inbound routes will have delivered hundreds of thousands of additional seats bringing visitors to Scotland, according to officials.

l The National Trust for Scotland's Battle of Bannockburn Visitor Centre has celebrated its 50,000th visitor since opening in March.

Lynn Forney Young, from Texas, was crowned 50,000th visitor to the site yesterday as the centre celebrates the year of the 700th anniversary of the 1314 battle.

Ms Young was visiting as part of a Daughters Of The American Revolution tour group.
