Google is your friend. There is a university in flagstaff so I bet there's a few. I remember there is a brewery we went to after doing a week long trip in the canyon.
Its pretty cool, but gets old really quick. Its been a long time but I remember hiking a while until you hit a sign that says not to go farther without sufficient water, but there are warnings throughout.
NAU is in flagstaff, but there really isnt a lot around it save for run of the mill chain restaurants and fast food joints. There is a mall about 15 minutes from NAU, and downtown there are a lot of hipster coffee shops and overpriced faux spiritual nonsense. An hour south is Sedona which is really pretty, but filled with old, rich hippie spiritual bullshit. Around an hour or so north of flag is a ski resort called snow bowl.
Always better hearing it from insiders than a web search.
So in other words, Flagstaff sucks for people in their 20s.
Any recommendations for cool bars or shit to do in a day at Flagstaff?
I don't know Flag that well, but my good friend does. I've just texted him and I'll reply with his answer later.
edit: "Lumberyard brewing company, the hotel Montevista bar and Charlie's are fun bars. Collins pub gets totally hopping too."
And i'm not jumping. Although I may take a piss over the edge.
