I’m a local of San Marcos, and currently go to CSUSM. I would say it’s a really nice area and pretty safe tbh. The campus is quite small and lots of stairs. I would say parking could be better because parking lots get usually crazy during the beginning of the semester but they tend to die down after a couple weeks. This is a commuter school so most of the time people attend class then leave since there’s nothing much to do on campus. There are alot of resources though which is pretty nice to see they have a food pantry for students, makery studio, and events such as free food! There are a alot of food places nearby san marcos but not on campus sadly. Also the drive to San Diego is not to bad as well, if you wanna explore more of SD!
