This 1.45 mile-long park goes in a line straight through the Lower West Side of Manhattan and Chelsea. The elevated park follows an old railroad and is a stunning combination of architecture, ecology, design, and art. Intriguing installations are dotted throughout the park, just waiting to be discovered. The installations were created by internationally renowned artists, and they explore themes ranging from politics, to climate change, to social justice issues. Besides the thought-provoking art, you'll also find super cool interactive furniture. The seesaw and keyboard benches are perfectly instagrammable rest spots. Follow the trail the entire way to get great views of the Hudson River and a unique tour of the city. As an added bonus, the park comes to an end in a trendy Manhattan neighborhood full of cute cafés, restaurants, and bars.
