Trail mix, also known as scroggin, is one of the most popular hiking snacks world wide. Typically it is a mixture of dried fruit, nuts, and other food such as chocolate. Trail mix can be bought commercially or assembled to suit the tastes of individual hikers.
There really is no end to what you can add to a mix and by making your own you end up with something that you are going to enjoy eating. Have a play with sweet and salty, with crunchy and chewy, as it’s not just the taste but also the texture but avoid chocolate in hot weather as it can melt.
