Visiting the Gateway Arch: Enter the monument through the Gateway Arch Visitor Center, which faces Fourth Street and the Old Courthouse. The Gateway Arch legs are exits only. Please allow at least 30 minutes to go through security.
The stars may be light-years away, but you can get a close-up peek at them right here in St. Louis. The recently transformed Gateway Arch grounds are more than just an oasis from the concrete and steel of the rest of the city. Learn about the surprising variety of animals and wildlife that actually inhabit the area.
Meet at the South Leg of the Gateway Arch at 8 p.m. for two twilight ranger-led interpretive talks. Weather permitting, guests can view craters on the Moon, the planet Venus, and other celestial objects via telescope at the South Leg, led by volunteers from the St. Louis Astronomical Society until 10 p.m.
