White Sands Missile Range, Highway 380, White Sands
The Trinity Site is where the first atomic bomb was tested at 5:29:45 a.m. Mountain War Time on July 16, 1945.
The 51,500 acre area was declared a National Historic Landmark in 1975. The landmark includes base camp, ground zero, and the McDonald ranch house where the plutonium core to the bomb was assembled. Visitors on the Trinity Site Tour usually see Ground Zero, “Jumbo” bomb casing, the McDonald House, one of the old instrumentation bunkers, historical photos, a Fatman bomb casing, and part of the original crater left by the explosion revealing “Trinitite.”

Turn on the Stallion Gate entrance and head south five miles of Highway 380.
