When most people think of New York, they think of the glittering lights of Manhattan, not the remote mountain range upstate called the Adirondacks. But that remote mountain range is exactly where the Adirondack Sky Center & Observatory is located. Positioned in Tupper Lake, NY, this observatory is completely free and open to the public. You can stop by to see the stars on every clear Friday night between memorial day and Labor Day. You can also come in winter on the first and third Friday of every month for some stargazing, as long as you don’t mind the cold temperatures.
