Now that the crush of summer tourists is heading home, there’s room for the rest of us at the High Line, the wonderful elevated park along the Hudson River. Every Tuesday in September and October, volunteer docents from Friends of the High Line are leading FREE walking tours that explore the hidden gems of the High Line, and tell us tidbits of High Line history. The tours are an excellent way to learn more about the park’s history, design, public artworks, horticulture, and the all-important information about how a group of dedicated people turned an abandoned railroad track into a public park that has made headlines around the world. Tuesday Tours of the High Line meet at 6:30 p.m. in the Chelsea Market Passage, on the High Line near West 16th Street. Tuesday Tours are free, but space is limited to 40 people, so arrive early to guarantee a spot. Bring your camera for the spectacular sunsets, and wear comfortable walking shoes.
