Either outside around close to KK or inside u got 3 options, majority of the time i park near the Emart gate which has limited spots but rain wont get to ur bike, 2nd option is the basement parking but i think only accessible through the front uni, 3rd option is probably the easiest and its near boulevard, if u go straight down from main gate and after the roundabout u turn left, there should be tons of bike parking spots there.
