4. Bring Your Own Snacks
Being on an adventure and living out of your trusty backpack can really drain you. Snacks might seem like a silly addition to your gear, but it can really help you keep energy levels high between meals and rests. Even in the cheapest countries to visit, local vendors know that snacks are necessary during travel, and they tend to jack up the prices on quick bites to eat; dodge this unforeseen expenditure and bring your own protein or granola bars.
