How do parties work at CU Boulder as a Freshman?

I’m an incoming freshman for CU Boulder, and I’m just wondering how exactly parties work for freshmen. Is it easy to get in? Hard? Where do the majority of parties happen for freshmen?

Parties happen in the dorms for most freshman.

Freshman can certainly go to “The Hill” and attend parties. Be careful over there.
There are plenty of parties in Williams Village, and other freshman dorms.
