Results of the survey by the House of Commons Communities and Local Government Committee found almost 90 per cent of respondees visit parks at least once a week, with almost half visiting two or three times weekly.
Almost 90 per cent had a "very positive" impression of parks' impact on well-being and the same proportion had that feeling about parks' affect on the community.
Some 60 per cent visit for 1-2 hours.
Two-thirds walk to the park, a quarter drive and the rest bike. Some 70 per cent of walkers live within 10 minutes of the park, while 90 per cent of overall visitors take less than 20 minutes to get to the park.
The July-September survey found the most popular uses for parks in order were to walk, for nature, to run, for peace, children, to see friends, for organised exercise, community events, to use a cafe, to bike, to picnic and for pets.
They found out about events through notice boards, word of mouth, Facebook, local press and friends' websites, in that order.
The Parks Inquiry sits again on 5 December with parks minister Andrew Percy MP the sole witness listed.
