Brit authorities are attempting to find a medic nicknamed Dr Novichok and a fourth man who helped the duo target ex-spy Sergei Skripal, it is claimed.
"Our friends had been suggesting for a long time that we visit this wonderful town", Petrov told RT.
"Salisbury?" their interviewer asked.
Another "Boshirov" said the "short 3,000 km hop from Moscow" to see the spire of the Cathedral was "well worth it".
The pair were caught on camera at Salisbury rail station on March 4, and minutes later another camera spotted them walking in the direction of Skripal's house - the opposite direction from the cathedral. Putin, speaking at an economic forum in Russia's Far East, described Petrov and Boshirov as regular citizens and definitely not "criminals".
And British journalists have been mocking the story on Twitter, highlighting the improbability of the pair's itinerary and route if they were truly tourists.
Britain has accused Russian Federation of responding with "obfuscation and lies" after the prime suspects in the Salisbury nerve agent attack claimed they visited the United Kingdom as tourists.

The Russians are accused of putting the nerve agent Novichok on the front door handle of former double agent Skripal in the poisoning attack on March 4. Sturgess later died after applying what she believed was perfume. While we were laughing at the incompetent hit men, he was surely laughing at the British, and the West more broadly, who have proved completely incapable of stopping them. While they acknowledged being the pair seen in images released by Scotland Yard, the men did not provide proof of their names.
RT ran part of the interview on Thursday morning, in which Petrov said: "We are those shown to you in the (CCTV) pictures".
Boshirov and Petrov went on to explain that they had also expected to visit other nearby attractions, but their plans were thwarted.
When RT editor Margarita Simonyan asked the pair why they travelled together, implying they might be a gay couple, the men said their private lives were off limits to the media.
Both Banister Dean and Enser said they believe RT is close to having its license revoked.
