Trinity Site, the location where on July 16, 1945, the first man-made nuclear explosion was detonated, is open only twice a year, and the Los Alamos Historical Society is offering a guided tour to the site October 1-2 for the fall opening.

The Society's Trinity Tour includes a two-day, one night experience via the Alamogordo southern approach through the seldom-seen interior of White Sands Missile Range. Departure from Trinity Site will be out of the northern Stallion Gate, with a lunch stop at New Mexico Tech in Socorro.

Bonuses include a visit to the young (5,000-year-old) lava flows of Valley of Fires, and the New Mexico Space Museum overlooking the Tularosa Basin, Holloman Air Force Base, and White Sands Missile Range. This excursion aboard a comfortable, restroom-equipped coach includes experienced tour direction with Georgia and Gerry Strickfaden, leading their eighteenth trip to Trinity.

The cost for Historical Society members is $400/person double occupancy and $500 for non-members, with an $80 single supplement for either. The price includes a tax-deductible donation to the Los Alamos Historical Society.

What's included: Overnight parking at Holiday Inn Express in Los Alamos, a seat on a luxury tour bus, hotel room, all meals excluding Friday night dinner, admission fees, tour guide.

Only 38 seats are available, so don't delay reserving yours.
