The 35-mile route will take in some of London's most stunning parks, waterways and views.
Rev Canon Kevin Walton, Canon Chancellor at St Albans Cathedral said: "St Albans to London is one of the busiest commuter routes in modern Britain.
"In this route we are offering a different kind of journey - away from the stress and busyness of modern living, and rediscovering our spirit and cultural roots as we tread the way from our vibrant capital to the home of Britain's first saint."
It's hoped the route - which was designed in five stages - will "boost the physical and spiritual wellbeing of those who may struggle to find the time in their busy city lives to undertake other pilgrimages".
Each stage of the journey is easily accessible via public transport.
St Alban is said to have been a Romano-British citizen who lived in the Roman city of Verulamium.
He died for his faith around 300 AD, close to the spot where St Albans Cathedral now stands, after giving shelter to a Christian priest fleeing persecution.
Partakers of the walk will be encouraged to reflect on his positive human qualities.
