Sheringham Park in Norfolk plays host to the launch of the National Trust's Walking festival today.
A nationwide search is being launched to find the country's ten greatest british walks to mark the start of the festival.
Walkers from around the country are being encouraged to upload information about their favourite walk to the Great British Walk website.
Walkers will need to describe their walk - and what makes it so special - and plot on to a digital OS map so that other walkers can follow the same special route.
Once submitted the walk will appear in an online map and users will be able to share the walks that they have nominated via social networking sites using the hashtag #GBwalk. The competition will run until Sunday 4 November.
