The Chelsea and England skipper admits that he frequently disappears for hours on end on his angling mission.
Terry told the Sunday Mirror: "I really got into fishing when I was younger and would spend hours attempting to make the elusive big catch.
"Obviously it's more difficult to find the time these days but when I get a quiet moment I tend to go off, rod in hand. I can sit there for hours, turn my mobile off and watch the world go by. I also have a great laugh and often go with Bobby Zamora from Fulham.
"My biggest catch is a 28lb carp, but over the years I've landed a few decent size fish."
Terry added: "I find when you're fishing you can escape reality and the pressures of life.
"I think it helps to have other interests and fishing in a way is like therapy to me.
"There is so much pressure in the game these days that you need to find time to shut off completely. Most of the time I'm in and around football, but I find that when I do go fishing it makes for a refreshing change from my usual environment.
"And there are moments when I sit there and think, 'This is the life'.
"It can be quite addictive, though, and as days off are so rare I probably don't go fishing as much as I like."
