Families who walk, cycle, scoot or skate to visitor attractions in and around Dacorum Borough have the chance to win prizes.
Since April, Dacorum Borough Council has been running the Active Explorer challenge, in partnership with the sustainable transport charity Sustrans.
Each time active families visit one of the visitor attractions, they receive a stamp and children get a free pin badge. Once three stamps have been collected, families are entered into a competition to win prizes, from cycling goodies to a family glamping holiday.
The closing date for entries is August 8. Scorecards and maps can be downloaded from www.dacorum.gov.uk/home/community-living/your-health-in-dacorum/health-wellbeing
