I really love to go hiking, I plan on going on my biggest trip yet next summer, Are there any things I should know before I go? 
Hiking is the preferred term, in Canada and the United State although it depends how long is your hike
Yea thats true. I want to hike a pretty long distance, But I am not sure on what type of stuff to bring except the essentials like water and snacks. 
i always make sure to have a solar battery with me at all times when hiking. The term bushwalking is endemic to Australia
A solar battery, Hmm that sounds really cool, What exactly do I need to use that for? 
You can use it to charge your phone/electronics and it charges by just leaving it in the sun
Oh that would definitely be very useful since Ill want to take lots of pictures along my hike. Thanks for the great info so far.  
 A day hike refers to a hike that can be completed in a single day, is that what you will be doing?
Yep ill day hike, Ill be too scared to hike at night and besides that would be dangerous with low visibility. 
It is a popular activity with numerous worldwide, so im sure you wont be going alone hahah
