Trinity Site Tour

The Trinity Site is where the first atomic bomb was tested at 5:29:45 a.m. Mountain War Time on July 16, 1945. 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.” Anyone can drive to the tour on their own. Bring car registration, proof of insurance, and a photo ID. If you are in a rental car, bring the rental car agreement and a photo ID.

The Stallion Gate will be open for entrance from 8am to 2pm and the site closes at 3:30. There is no food or water or other services along the route, so come prepared. Port-a-johns are available. Riders must not leave the road due to the presence of unexploded ordnance. Photographs may be taken at the Trinity Site but not anywhere else along the route. Dogs are welcome but they must be well-behaved, leashed and picked up after. Bring bags for dog waste.
