Be prepared for hiking with this list of outdoor gear.

ClipStick multi-tool.

Multi-tool

Taking a multi-tool like a Swiss Army knife (doesn't have to be this, but just for reference) is a pretty important staple in hiking outdoor gear. If you're not planning on a long trip or camping, it's still important as a "you never know" kind of tool. You can even pick them up cheap now.
Hiking boots

Hiking boots

A great, comfortable pair of water-proof hiking boots are also key. The boots help to stabilize your feet and ankles during uneven terrain. Having a pair that is water-proof is good because you never know if/when you'll encounter unexpected water and you want to remain dry.
Hiking jacket

Hiking jacket

A light-weight, but warm, jacket is a good thing for your outdoor gear. Especially if you're going to be out in a colder weather, but you know that exercise makes you warm.
Hiking backpack

A hiking backpack

This is one of the most essential pieces of outdoor gear you can take with you for hiking. It's the thing you will store all of the other needed supplies in. You don't want anything too bulky that it'll weigh you down, so be wary of that. Try on a few before you buy. Make sure it has the right amount of space and/or pockets for you to put all of your essential hiking supplies in it, too.
Sunscreen

Sunscreen

Always wear sunscreen when you're outdoors and remember to take some with you to reapply. You can also bring along a hat, just don't forgo the sunscreen.
A hiking map.

Map of the area

Whether the map is on your phone or a physical, paper map, always have a map on hand; especially if you don't know the area that well! I usually recommend a paper map no matter what.
Food/snacks

Food/snacks

Even if you don't think you'll be hungry, just take some food with you. Grab easy to pack items like nuts, granola bars, beef jerky, squeezable pouches, you name it-- just take it.
