In total, 54 routes have been devised, which span nine regions across England.
The idea was inspired by recent Oxford University research that revealed people who have a local pub are generally happier, have more friends and are better connected to their community, according to CAMRA.
“Pubs play a huge role in improving people's sense of enjoyment, relaxation and wellbeing,” CAMRA chairman, Colin Valentine said.
“Particularly at this time of year, issues around loneliness come to the fore and going for group walks and visiting your local pub is a great way to reach out to your local community and make friends.
"These excellent pub walks combine gentle exercise with an opportunity to relax and socialise in pubs serving some superb beers. We hope that the joint guides will encourage more people to go out on a pub walk this Christmas.”
Eleanor Bullimore, engagement manager at the Ramblers, added: “There’s nothing like a good walk over Christmas to blow away the cobwebs and enjoy amazing winter landscapes.
"We hope lots of people will step out on one of our special CAMRA-Ramblers routes and enjoy the walking and the chance to warm up afterwards in the pub.”
