Some might say it needs to be difficult, have a certain elevation change, require a blah blah blah. It literally doesn’t matter.
What matters is that you go outside and do something you wouldn’t have done otherwise.
If you have friends who hike, ask them to take you on a trek. Most people are happy to share their expertise, let you borrow gear and introduce newbies to their favorite trails.
If you don’t know any hikers, many cities and towns have hiking clubs that regularly plan outings. You can find hiking classes, outings and events through REI Experiences. Online groups, such as REI Conversations or Meetup, are also a great way to find hiking buddies.
Hiking alone: Experiencing the outdoors by yourself can give you a sense of freedom and adventure that are hard to find elsewhere. But it can also be intimidating and lonely at times. If you’re new to hiking, we recommend finding a companion to keep you company. That person will also be there to lend a hand if you happen to get hurt. If going alone really is your only option, then start out with short trips to popular hiking destinations and make sure someone always knows where you’re going and how long you plan to be gone.
