Named after President James Madison, the park is between East 23rd and 26th streets near the Flatiron Building. If you like just doing nothing, then set up a picnic blanket or grab a table and people-watch. The park is popular for art installations and rollerblading, and was where the first public Christmas tree in the United States was displayed in 1912. You’ll find food vendors around the edges of the park (not to mention the first Shake Shack, inside it) and a dog run area.

“You should visit this park because it’s large enough for peace, small enough for safety, and within walking distance of restaurants and office buildings.”
