First decide where (state or region) you would like to live, that is, where would you like to spend your career. Then go to college in that state. Major in wildlife management and minor in criminal justice. Having a high GPA will help you later in application process.
While in college get summer jobs with the state wildlife management agency, this will get you known and you can become familiar with how the agency works, etc. And yes, these jobs may be pulling weeds or other manual labor, but this is the “proving ground”; do poorly in these jobs and you will not have a chance at a job later on.
When, and if, you get hired to become a game warden you will most likely have to attend the state’s law enforcement academy for 2 to 4 months.
If you have done any drugs since junior high or early high school you should probably think about another career. The tests (written, oral, psychological and lie detector) you will have to take to get hired will eliminate you quickly if you are not the “law enforcement” type.
It is very competitive, the state I live in gives the initial written test to about 100 people for every 2-3 they finally hire.
