You will need a rucksack or a beltpack to hold all your equipment. The size will depend on how much
equipment you have which will be determined by the weather and how far you are walking. You should take:
sufficient food and drink for the walk and some extra in case of unforeseen circumstances
a hot drink if the weather is cold
a foam mat or bag to sit on
suncream
a map and compass if not walking with a group
a first aid kit and any medecines you might need
a torch, particularly in winter months, in case you do not return by dark
