Peel travelled to many countries outside his home in England as part of holiday trips and his work with the BBC and other media companies, despite his fear of flying. Scotland, Wales and Northern Ireland along with England are considered countries of the United Kingdom, hence why the first three are included in the list below, as Peel's trips outside England.
- Andorra: Peel mentioned visiting the country in 2001 especially the town of Les Escalades in an article in the Radio Times (later published in the Olivetti Chronicles).
- Austria: Peel presented shows for Austria's Ö3 radio station between 1989 and 1994. On his 05 August 1991 (Ö3) show Peel relates a visit to Vienna, during which he went to see John Lee Hooker, and took exception to the contributions made by the organ player in the band, each of whose solos "in the manner of Keith Emerson" caused John to scream abuse at him. A year later he visited the country again as part of the BBC's Radio campaign on work opportunities in Europe.
- Belgium: Peel visited Brussels during the Eurovision Song Contest in 1987 and met the Royal Family at that event on Peel 060 (BFBS). He was also present at the Heysel stadium disaster in the same city in 1985.
- Bulgaria: Peel first visited Bulgaria in the summer of 1991 which was reflected in two BBC World Service programmes, devoted completely to the Bulgarian rock scene: 01 August 1991 (BBC World Service) and 08 August 1991 (BBC World Service). He also claimed on his show on 22 November 2001 to be one of the few people in the country to have visited Bulgaria twice (1991 & 1994):
"The second time I went … I gave a press conference in something like the grand hall of the congress of the people. There were about 100 journalists in there and none of us knew why we were there. And one of them said, ‘Is it perhaps because you’ve been to Bulgaria twice?’ And I said, ‘Well, that’s as good a reason as any.’ So we kind of accepted that was why it was."
- Czech Republic: Peel travelled to Prague on his European road trip, that was broadcast on 16 October 1992 as part of the BBC's Radio campaign on work opportunities in Europe.
- Denmark: Peel mentions coming back from 10 days in Denmark and Sweden on his 29 October 1993 (BFBS) show, where he was presenting a BBC Radio One documentary called John Peel In Scandinavia. On his Peel 059 (BFBS) show from 1st May 1987, Peel mentions finding his visit to Denmark a disappointment:
"As I said at the beginning of the programme, just come back from a couple of weeks or about 10 days driving around in Scandinavia. People warned me before I went there that it was very expensive, and indeed this turned out to be the case. What they hadn't warned me about too was that everything is shut, and when I say "everything", absolutely everything was shut: nothing was open whatsoever, even like the Tivoli Gardens in Copenhagen, which are world famous, Easter Bank Holiday, you think they'd be teeming with people: shut. Everything shut: quite extraordinary. Except actually there was a record shop I found that was open, but the prices in there: it was like £9 for one of those Peel Session EPs, so I didn't buy any records."
