4×4 Quad Bike

What do I need? Dirt Quad Bike?? Easy 10 points!?
I love being outdoors. I'm really good on my bike. I think I want to get something like a Honda, but surely not. Definitely something reliable. I want to walk trails, but not for racing. We like to collect rocks, so you probably would have a quad. I think maybe something with 4×4 and used. Maybe about $ 2,000. (I know it's not much money.) But I know absolutely nothing about these things. So what kind of quad do you recommend? Dirt Bike Or maybe but probably would get a quad. Thank you very much. I give 10 points for best answer! I have 14 years and 5'7 "and 140 pounds if that solves. I am not a child whimpy. So I could probably handle something big.
Quads are nice, but are difficult to get through trails. I would get a dirt bike a lot more fun, easy to handle and can go anywhere in the itself. The choice is yours. Good luck
