Trail mix or scroggin is a type of snack mix, typically a combination of granola, dried fruit, nuts, and sometimes candy, developed as a food to be taken along on hikes. Trail mix is considered a great snack food for hikes, because it is lightweight, easy to store, and nutritious, providing a quick energy boost from the carbohydrates in the dried fruit or granola, and sustained energy from fat in nuts.

The combination of nuts, raisins and chocolate as a trail snack dates at least to the 1910s, when outdoorsman Horace Kephart recommended it in his popular camping guide.

Ingredients commonly found in trail mix:

Nuts, such as almonds or cashews
Legumes, such as peanuts or baked soybeans.
Dried fruits such as raisins, cranberries, apricots, apples, banana chips, sultanas or candied orange peel
Chocolate: chocolate chips, chunks, and M&M’s
Breakfast cereals such as granola
Rye chips
Seeds, such as pumpkin seeds or sunflower seeds
Carob chips
Shredded coconut
Ginger (crystallized)
