6. Hit the trails.
Can’t afford a trip to Argentina? Hike the Appalachian Trail or any number of other nature trails across the country for a day or two. (You have to really do it, though. Just telling your staff you’re doing it, leaving your car there, and catching a plane south of the border doesn’t count.) Or research the trails near your destination, and include some day hiking in your itinerary.
7. Try the rails.
If you live near an Amtrak station, pick a city a few hours, or even a day, away, and discover somewhere new. Or, visit www.railstotrails.org and combine your camping trip with a bike ride (or hike) along an old rail line that’s been converted to a nature trail.
