Council bosses claim it will be the 'biggest and best' festival to date, with 36 activities over eight days.
Highlights include guided walks around beauty spots such as West Park, East Park, Pendeford Mill, Northycote Farm, Bantock Park and the Smestow Valley.
There is also the annual 12-mile long Walking for Health Challenge Trail.
Councillor Paul Sweet, Wolverhampton council's cabinet member for Public Health and Wellbeing, said: "The Wolverhampton Walking Festival offers a fantastic range of easy, moderate and more challenging walks to suit people of all ages and abilities.
"Walking can improve your health and happiness, so it's also a great way to get or stay in shape and also discover parts of the city you may not have seen before.
"Everyone is welcome, and best of all, the walks are totally free."
The Wolverhampton Walking Festival is organised by the council's Healthy Lifestyle Service, with support from WV Active, the British Heart Foundation, Nordic Walking UK, the Ramblers Association, Wolves Community Trust, Wolverhampton Art Gallery and Wolverhampton Civic and Historical Society. Walks take place from May 13 until May 21.
The programme features a moderate 90-minute walk over Bushbury Hill and around Northycote Farm on the opening Saturday.
