Meanwhile Karen and her coach Frank Gray were plotting her next move. He set up a trip to Italy for the end of March 1966, where Karen would compete in an international event in Milan. The trip was due to an invitation from the Italian Swimming Federation, via the South African Swimming Union, who did not approve of Frank accompanying his swimmer as a coach - they always sent their own man Alex Bulley as coach. Frank made it clear that he was going anyway - with or without their approval. Funded by generous contributions from local sponsors, Frank Gray and Karen, accompanied by her mother Yvonne, set off for Milan. Coming from an Afrikaans town like Kimberley - it was to be an experience for her!
At the 33,3 metres Piscina Cozzi of Milan she was compete against swimmers like Romanian swimmer Cristina Balaban who won a bronze medal in the 100 m backstroke at the 1966 European Aquatics Championships and Russian Natalya Mikhaylova, who would finish second behind Karen in the 100m backstroke event. Frank Gray wrote from Milan - explaining how his champion was coping with the attention. In the end it was all probably a bit much, as Karen ended up in bed with a severe cold! But like any teenager, she was soon back on her feet to be a tourist in Naples and Rome, giving exhibitions to schoolchildren. Before leaving for home she made an attempt on the 200m-backstroke world record of 2:27,7, held by Cathy Ferguson. Having just seen off the American challenge in Durban, she must have fancied her chances of setting a new record. Swimming in the mosaic magnificence of the Foro Italico she had a bad start, and failed to break the world record, despite a split of 34,4 over the last 50. However - she was to break that record twice in the next few months, and again in 1968.
Returning to Kimberley again was not to be without some difficulties. In what must have involved some high-level diplomatic scrambling, the Muir's and Frank Gray were allowed to travel home - without any passports. Frank Gray wrote a report of the their trip for the people back in Kimberley, who were following Karen's travels in the Diamond Field Advertiser.

In July 1966 Karen undertook another extended Springbok tour - to France, the USA and Canada. The British ASA, probably tired of the South Africans winning all the titles at their nationals, had changed their rules to allow only British-born swimmers to swim in the ASA nationals. Instead SAASU had arranged a tour of France and the USA for July - and also to Canada to compete at the British Columbia centenary celebration gala.
In France they were to swim unofficially in an international gala involving Spain and Italy, while in the USA they would take part in the Los Angeles Invitational and the US Swimming nationals in Nebraska. The Canadian invitation would extend that trip right up until the end of August. Luckily for Karen's academic aspirations, the trip coincided (mostly) with the SA winter school holidays - certainly a factor in deciding whether to allow her so much time away from school.
At the time visiting Australian great Ilsa Konrads had written a series of swimming articles for a local newspaper, in which she criticized the arrangements made by SAASU for the trip. In particular - their continued insistence on Alex Bulley being the only coach on tour, and their refusal of permission to accompany her coach Frank Gray to London, where she would have been able to prepare for the tour in a heated pool. Friction with SAASU and the management of Karen Muir was to have a big impact on the 1967 tour.
Swimming training in cold water, which is all Kimberley could provide, was not a viable option. As a result Karen was forced to travel to Johannesburg, to train in the unfamiliar surroundings of the Summit Club in Hillbrow.
On tour, Karen accompanied by the older Ann Fairlie - once again received extensive press attention, while the swimming officials scheduled sightseeing trips, which exhausted the swimmers. Their first gala was in the French town of Beziers, where they were allowed to swim unofficially in an international event including Spain, Italy and France. Although not part of the official international competition, the South African swimmers certainly made an impact as first Ann Fairlie and then Karen Muir world backstoke records.
