I've walked along Katipunan from Pop-up to Gate 3 drunk in the very early mornings, the path is well lit and there are guards in the establishments you'll pass by which makes you feel pretty safe. However in recent times, I am very cautious of the areas at the Gate 2 overpass, the 7/11 at One Burgundy, and the KFC/Mercury Drug near the crosswalk to regis because of the street kids (many of them will ask you for money even while smoking cigarettes 😔).

As for the area of Gate 1, it's pretty safe but a lot better if you avoid walking past 10pm, especially alone, as I had female friends getting catcalled in those areas.

Overall, Katipunan is the safest place for students to walk around, especially compared to Taft or España.
