I went to Penn State as an undergrad and there are soo many things to do! Penn State is a huge sports school so if you enjoy that I would definitely suggest getting season tickets for football - even if you don't, we take tailgating very seriously and it is a blast- but pretty much all of the sports teams are awesome! There are also intramural sports that are pretty relaxed that you can get involved in and most of the fitness centers have been redone/have classes you can take (its included in tuition!). There definitely aren't as many options for going out as you would get in NYC but they have a little bit of everything downtown and most bars have a theme night - Mad Mex has margarita Monday, Darkhorse has sex trivia and Pickle's has country night on Tuesday's, and so on. There is a small mall about 15 minutes from campus but when I say small i mean probably like 30ish stores. They also have this really great festival in the summer called Arts Fest. A bunch of local artists and vendors set up along the streets downtown and on campus. They have lots of live music too! You are also not far from Mount Nittany if you like hiking or Tussey Mountain if you like to go skiing/snowboarding. Also one of the most amazing things you could do is get involved with THON. THON is a 46 hour no sitting, no sleeping dance marathon for pediatric cancer research. You fundraise all year and then it ends with the dance marathon in mid February. It is honestly one of the most rewarding and humbling things you could do during your time there.
As you can probably tell I loved everything about Penn State but it really is such an amazing school all around. I hope this was helpful and also congratulations on getting in! :)
