People are enjoying the outdoors closer to home and getting to places on foot while making less use of cars, according to Scottish Natural Heritage.
According to the results of a survey, visits taken on foot increased from 50% in 2004 to 67% in 2011.
Where transport had been needed for a trip, car usage fell from 43% to 28% over the same period.
SNH said 83% of adults surveyed said they had made at least one trip outdoors for leisure or recreation.
The figures are contained in the newly-published Scottish Recreation Survey.
Walking was the most popular activity, with 74% of outdoor visits last year. Family outings made up 9% of activities and cycling, or mountain biking, 4%.
The report added: "Forty eight percent of outdoor recreation visits were accompanied by a dog or dogs, a similar proportion to previous years.
"Overall, 47% of visits were taken alone while 39% were taken with family members."
