The number one rule of campsites is to select your campsite before dark. No end of trouble can be avoided by this one simple rule. A protective windbreak of trees or bushes in winter camping is essential. Shade and breeze in summer is equally important. Inspect the ground for level conditions.
Grassy areas are ideal.
Avoid closs underbrush or swampy areas, which could be a breeding ground for pests. The spot should have good drainage to be free of srunoff during heavy rainfall, and should be away from dead timber which may crash on the campsite during a violent storm. Determine the eastern horizon, and face the tent opening toward the morning sun. A quick view of the surrounding is always recommended. Do this before twilight if possible, so you don't get hurt inadvertantly because you make a wrong step.
