How often do you chuck the daysacks in the back of the car for a day out walking in one of the UK's beautiful national parks?

That and several other questions are part of a questionnaire you are being invited to complete as part of a project to design a "ground-breaking" new mobile phone app.

The Sustainable Uplands project team, led by a team from the University of Aberdeen, is working on 'enhanced reality' national park walking routes that enable users to contribute financially to park maintenance.

Available via a smartphone application, the new routes will offer users some of the latest landscape research findings to enable them to gain a better understanding of the trails, coppiced woodland and waterways they walk through.

The survey, available to complete here, asks a variety of questions, including how often people go walking, what types of walk they enjoy (such as challenging hikes or walks to places of interest), what navigation tools people use, and what information they would like about the routes they are walking.

Recently, the Yorkshire Dales National Park launched a new smartphone app, the first of its kind developed by a park authority.

It is packed full of walking, cycling and mountain biking routes, and is available to download free of charge.
