Any fan of the Cathance River Education Alliance in Topsham, Maine should have this handy tool! The CREA app for iPhone is an innovative new companion for hiking on our trail system. Rather than having to figure out where you ended up on a trail map, the CREA app finds your location on the map for you so that your hike can be as pleasurable and stress-free as possible. In addition to being great while on the trails, the CREA app is the best tool to learn about CREA, get information on upcoming events, plan your visit with trail descriptions and photos, and get directions to the preserve.
