1. Select the state you want to find a campground in. You can also add the city if you know which city you want to stay. Click "Find Now"
2. A map then comes up with pins of all the campgrounds in the area, and shows their proximity to highways and roads (the map appears toward the top of the page)
3. You can zoom in on the map with the white ladder looking thing on the left of the map
4. If you click on the pin that is closest to the highway or road that you want it will give you the campground information,
the campground's page on CampingRoadTrip, and it will allow you to find directions from or to that campground
Hope that helps!
