If backpacking, try to stay only one night at each camp site. Another major problem in parks today is pollution. Noise pollution, litter, graffiti, and smog are making our parks less enjoyable for everyone. Don't litter or pollute. Before you throw away the plastic rings that hold your six pack together, cut the rings.
Some people pollute without realising what they do is a problem.
Come here to learn what you may be doing wrong. Follow park rules and use common courtesy. Some basic park rules and suggestions can be found here. Enjoy your park on foot or use public transportation. Report any signs of vandalism or theft to your park Ranger.
