It's Saturday morning and the weather is perfect so you decide to head off to a local National Park with friends to do a hike. Nothing complex, but it's more than just a 20 minute walk and you may or may not have a phone signal so you start thinking about what you will take with you. This hike won't require any overnight equipment such as a tent or sleeping bag but you're not really sure what you should take. This is where it can get confusing - take too little or take the wrong things and you may not be comfortable. Take too much and the result is the same.
So what should you take on a day hike?
