NYC WTC Solar System Walk

☉ The Sphere (Koenig Sphere)

Starts at ☉ The Sphere (Koenig Sphere). You'll get directions there, then scan the GO code on your card when you arrive.

A true-scale stroll up the spine of Manhattan, from Fritz Koenig's Sphere in Liberty Park out to the gardens of Fort Tryon. The inner planets cluster within a few blocks of the WTC; the outer giants stretch the walk into a half-day journey north. Wear comfortable shoes — Neptune is a real hike.
