Poison ivy loves the sandy soil of area beaches and is found alongside seashore trails, so there is a lot of it to avoid. (It also helps anchor the sand in place, so the plant has quite a positive role on the shore.) Poison ivy generally has groupings of three shiny leaves. They may change color depending on the season.
If you know what to look out for and avoid it, you'll be fine. If you think you have come into contact with poison ivy, wash the affected area with soapy water or use a product that can cut through the oils if used close enough to first exposure.
