It's a strategy you'll have to work out depending on what kind of work you want to do. I was a park naturalist and historian, but at the parks where I was a naturalist they have since shifted to having more protection (law enforcement) rangers than anything else, due to the change in use of the parks.

You'll find ranger jobs with local government entities, cities and counties, you'll find state park ranger jobs, and several agencies of the federal government have park ranger positions.

Starting as a seasonal is a good way to get your foot in the door. I've published articles about this process, but they're old enough that the process has no doubt changed considerably.

Choose the agencies and localities you're interested in and look at the job requirements. Do you fit them? If not, work on getting those skills, and while you're at it, consider doing some volunteer work. Getting trained as a docent, for example, is a good first step, but you need some solid scholarship behind you to move beyond volunteering.

Good luck. There was a thread running recently where different Mudcatters who had been or still are rangers shared a few thoughts about it. Do a search or extend the number of days you can view the thread titles out for a few months and you'll find it.
