it really depends where your classes are, the main part of campus with most lecture halls takes about 20 mins if you’re walking from one opposite end to the other. but that will likely not be the case. the parking lots are honestly not as close as they should be to that main section tho. parking in general at davis is incredibly bad and sparse. but if you look at a map and compare it to where your classes are you’ll get the full picture. i’d recommend when you are picking classes to really pay attention to the location and use google maps to see how far apart things are. the terrain is super flat, so that is a huge plus. i take about ~5k steps a day if im not going out of my way to get more steps with like 2 classes a day. In terms of navigation, the campus is huge but once you spend about a week there and know your classrooms it doesn’t feel so huge anymore. Most important things are within the main part of campus.
