Some good advice in this thread. Some horrible advice in this thread.
Hi. My name is [icon] and I'll be your Memphis tour guide today. The fact that Abe says Memphis takes 3 hours, but mentions mud island as one of the two stops (a destination I wouldn't put in the top 50 things to do here) is kinda funny.
Memphis airport sucks. Small and expensive.
It is a straight shot of exactly 200mi of 4 lane divided freeway between Memphis and Nashville... If that takes you 4 hours, please stay the #### off I40 so the rest of us won't have to run you over while driving 80-90 like a normal person. 3 hours... Max. I've done it in a shade over 2. It is a pretty damn boring stretch of road though.
Beale street is okay. Tourist trap and good for a night. Maybe two. There are 3 other entertainment districts downtown that have solid options as well as scattered other options worth seeking out in their own right. Overton Square and Cooper/Young are both great bar/restaurant districts that most locals like myself frequent instead of Beale. Overton alone has something like 30 options in a 1 mile stretch. Uber/lyft are your friends.
Shelby farms, the largest municipal green space in the nation (4,500 acres), has zip line, ropes courses, paintball, 20 lakes for fishing or boating (rent kayaks/canoes/paddle oats), guided horseback rides, networks of well-maintained mountain bike trails, huge expanses of paved and unpaved hiking trails and other outdoors activities. It's also undergoing a massive $70MM Renovation/expansion as we speak. Hiking/camping can be found further north in Shelby forest. Our zoo is consistently rated among the best in the nation.
We have more music related exhibit destinations (rock and soul museum, stax museum, Graceland, etc) than most other cities. I am not an Elvis fan, but Gracelands self-guided audio tour is amazing.
Nearby there are tunica (few solid casinos 30min south) or southland greyhound park (divey but fun casino / dog track just over the bridge in west Memphis).
Alton Brown recently named us his top food city in the nation... There has been an explosion of fantastic restaurants in just the last couple years.
Live music is not an issue, between larger venues like FedEx Forum, Minglewood Hall, New Daisy Theater on Beale, Hi Tone, etc... As well as dozens of mid-line spots like BB Kings blues club, Lafayettes Music Hall... Plus tons of other bars lining Beale street or any of the other entertainment districts... Life music is Everywhere here.
Our downtown ballpark (AAA for cardinals) is actually one of the nicest in the country, with great affordable seats, good food, and cheap beer.
Hotels: Westin, Peabody, Madison. That's it for you. If possible, align your trip with a festival of sorts for maximum impact.
I'm certainly not trying to say Memphis is one of the best cities in the nation... But if you wanted to really see the city, you'll need to spend 3-4 days here, not hours.
Let me know if you have any questions... Hell the GF and I would love to meet ya out for a night or so and show you around.
