If you haven't heard of or been to the High Line, I highly recommend a visit during your next trip to NYC. Formerly an elevated industrial rail line, the High Line was left abandoned in the 1980s. After years of planning, the High Line was given to the City of New York and plans were put in motion to transform the rails into an elevated public park. The last time I visited the High Line was at least 5 years ago when only 1 (or 2) of the 3 phases were complete. Now, the entire park is open to the public, all 1.45 miles. I couldn't get over how clean, plush and well designed the space has become, not to mention the views of Manhattan are pretty spectacular!
