Recruiter here doing specifically financial services executive search. My suggestion is to look at the heads of HR at the largest corporations (JPMorgan, Walmart, etc) and just look at their bios. You'll see what the typical paths are to get to that top level. Check out their linkedins for progression too.
Like some of the posters above have mentioned, some typical paths in HR are comp & benefits and internal recruiting.
There are also a ton of HR consulting firms that you might want to check out (ex. willis towers watson, mercer, pwc, EY and Pearl Meyer are some compensation consulting firms). We just spoke to an MD at one of these and he was making $1million/yr.
If you want to go into recruiting, you can go inhouse and do internal recruiting or do it at a recruiting firm - either lower level staffing agencies, or executive recruiting (korn ferry, russell reynolds, heidrick, etc). The average entry level recruiting analyst (straight out of college) at a korn ferry is usually around 50-70k all in, in NYC. The partners here are probably making $1.5million/yr.
It's crazy how much some of the top HR people make...for entry level roles, you should check out glassdoor to get a sense of comp.
