How does campus life at San Diego State compare to Arizona State for undergrads?

For undergrad campus life, San Diego State usually feels more like a traditional, contained college experience, while Arizona State often feels bigger, broader, and more spread across different kinds of students and activities. SDSU has a compact residential campus with a strong on-campus social scene, visible school spirit, and a student body that tends to interact in the same physical spaces. ASU, especially in Tempe, is very active too, but the energy is more diffuse because the university is larger, serves many different student populations, and has a more mixed campus rhythm.

SDSU tends to appeal to students who want campus life to be the center of their week. A lot of student life happens on or near campus, and the setup makes it easier to run into the same people, go to events, and feel plugged into a shared social environment. There is a strong sports culture, plenty of student organizations, and a reputation for students being socially active in a very visible way. The San Diego location also shapes the vibe: beach, outdoors, and a laid-back Southern California feel are part of everyday life.

ASU fits students who want a high-energy environment with a huge menu of options and more freedom to build their own version of college life. Tempe is lively, with lots of clubs, events, Greek life, athletics, and nightlife nearby, but it can feel less intimate simply because the student body is so large. Some students love that scale because there is always something happening and many different scenes to join. Others find that it takes more initiative to create a close-knit routine.

If your main question is which school feels more connected on a day-to-day basis, SDSU often has the edge because of its more self-contained campus and stronger single-campus identity. If you like the idea of a massive university where you can find almost any social niche, ASU can be exciting, but it may not automatically feel as unified.
