There are a few things you should know before hiking, even if you’re just going for a short walk. First, make sure to pack plenty of water and snacks. Hiking can be thirsty work! Second, be aware of your surroundings. If there’s any chance of rain or snow on the forecast, bring an umbrella or jacket. And finally, always take caution when crossing streams or climbing steep hills – stay close to the trails and use common sense when deciding whether it’s safe to cross a stream or go up a hill.
