The first man-made nuclear explosion was detonated at Trinity Site in southern New Mexico 75 years ago this July. The site is open to the public twice a year, and the Los Alamos Historical Society is offering a tour for the spring event, April 3-4.

Experienced guides Georgia and Gerry Strickfaden will be leading the tour, marking the 17th time they have taken groups to Trinity Site, a national historic landmark where visitors experience ground zero and reflect on this historic event as they walk through the McDonald Ranch House where the Gadget’s plutonium core was assembled. 

The trip is a unique two-day and one-night excursion via the Alamogordo southern approach through the seldom-seen interior of White Sands Missile Range. Also included on the trip is a visit to the young, 5,000-year-old lava flows of the Valley of Fires, the New Mexico Museum of Space History overlooking the Tularosa Basin, and Holloman Air Force Base. Departure from Trinity Site will be through the northern Stallion Gate, with a lunch stop at New Mexico Tech in Socorro.

Reservations for the tour must be made by Monday, March 9, and tickets sell out fast. Only 38 seats are available. The cost for Historical Society members is $400/person double occupancy. For non-members, the fee is $500. Single accommodations are an extra $80 for either. Reservations can be made online at

Refunds, minus a $50 processing fee, can be made through March 13.
