Southern Maryland isn't exactly dangerous territory, but visitors should take some precautions. Poison ivy is widespread along forest edges. It shouldn't prevent you from enjoying nature, but learn to recognize it before you go off-trail. Ticks, mosquitoes and chiggers abound during summer months. Humidity can be quite high during the summer, so stay well hydrated. The Copperhead, a poisonous snake, is found in some areas. Jellyfish live in the Chesapeake Bay during warm-weather season, and can be a hazard to swimmers.
