Connecticut’s Trails Day is being held this weekend.  The first weekend of June is dedicated to the nationwide hiking initiative.  Several hikes are scheduled this weekend in the Greater Danbury area.  The Norwalk River Valley Trail organization will sponsor a Saturday morning hike, starting in Danbury at Tarrywile Park. The approximately four-mile hike will start outside the Tarrywile Mansion at 9:30am, but will be canceled if it rains. A two-mile hike in Redding is being held Saturday morning at the Ground Pine Sanctuary off Sport Hill Road.  Hikers will cross rolling terrain in the sanctuary, an intermittent stream and a vernal pool.  The hike will take place rain or shine from 9am to 11am.
