If you have a school bookbag, you are good to go for dayhiking.

Bring the "ten essentials", plan your water and clothes for your environment, and have fun. Remember a map!!

If you have fun dayhiking and want to invest in that activity, buying a camelbak that suits your desires can be a good investment, particularly if you want to keep moving in rough terrain and drink at the same time. Or you can just spend $20 on a bladder and toss it in your bag, running the tube out a zipper.

Earlier posts RE buying a backpacking backpack apply.
