Look up the weather forecast for the campground during your stay. If rain is a possibility during your trip, select a campsite in a wooded area and set up your tent underneath a dense canopy of trees. While the trees won't completely keep you and your gear dry, they will help cut down on the water that gets to your tent.
Check with an on-site camp host to find out if certain areas of the campground are better than others. The host can provide insider information, such as whether certain campsites have higher concentrations of bugs and which sites offer the best views and the closest proximity to campground facilities and surrounding trails.
Decide how close you want to be to campground facilities and choose your campsite accordingly. You'll have easy access to restrooms and water faucets if your campsite is close to them, but you'll also have to sacrifice seclusion because other campers will be coming and going to use these facilities, as well.
Select a site close to water to give yourself access to a handful of activities, such as fishing, swimming and boating. Be aware, however, that, depending on the time of year and your location, bugs, and mosquitoes in particular, might be in higher concentration the closer you get to water. If that's the case, you might want to put some distance between yourself and the water.
Choose a campsite that has a large, flat area for your tent that's free of large rocks, tree roots and shrubs. Pitching your tent on a graded surface can make for restless and uncomfortable nights, and spots that are littered with rocks and brush can be difficult to clear.
