Hopkins is in a pretty good area and its immediate surroundings are being extremely gentrified at this moment. The school has one of the largest private security forces in the nation and does a good job watching over students. There are very bad parts of Baltimore but that area is mostly west or east baltimore and there’s not really a reason to be hanging out there (draw a large X dividing baltimore with the Hopkins campus as the center and you’re safe to walk freely in the north and south quadrants).
There are so many things to do like explore a few of Baltimore’s art districts such as Station North and Mount Vernon. There’s also the inner harbor that is packed with a ton of restaurants and shops. One of my favorite things to do are weekend trips to DC since it’s only an 8$ 45 minute train ride away and there’s a plethora of museums, restaurants, clubs, and things to do at the nation’s capital. I mean it’s hard to list everything and I’ve never felt myself out of fun things to do. You can PM more personal questions : )!
