There are many types of walking aids, from walking sticks to hiking and trekking poles – made from a wondrous variety of materials.
I prefer a simple wooden stick to aid me on my travels, and it has come in very handy when clearing away brambles, testing the depth of mud or water, and even in being a support when taking pictures.
In the Brecon Beacons it recently came in very useful in testing the depth of snowdrifts!
