The Northern Echo is promoting positive activities for children and teenagers throughout the summer holidays as part of the No Messin' campaign.

The campaign aims to highlight the dangers of messing about on railways, while promoting alternative activities.

Every week, we will publish a column listing activities on offer throughout the North-East and North Yorkshire.
