Don’t miss the fascinating Trinity Site Tour! The Trinity Site is where the first atomic bomb was detonated on 5:29:45 a.m. Mountain War Time July 16, 1945, as part of the Manhattan Project. There, you will walk around Ground Zero of the first atomic bomb (the Gadget), and you will take a shuttle to the McDonald Ranch House, where the plutonium core was assembled.

Tours to the public only occur once a year, and this bus tour is nearly sold out.

Check-in is 6 a.m., tour buses depart at 7 a.m. and return at 3:15 p.m. (estimated time varies), Oct. 18, 2025. Cost is $155 per person (Museum members receive 10 percent discount). Register here, the deadline for reservations is until all buses are full.

“If you’ve never been to Trinity Site, this is absolutely the best way to travel there. On the coach, you’ll be able to relax and enjoy the trip comfortably and learn about the bomb and Trinity Site from our volunteer travel guides,” said Johnny Powell, President of the International Space Hall of Fame Foundation.

The roughly 140-mile round trip from Alamogordo to Trinity Site is non-stop, although the motor coaches do have onboard restrooms.

Attendees will be treated to breakfast snacks and lunch, bottled water, and admission into the New Mexico Museum of Space History that day.

Cameras are allowed at Trinity Site; however, they are prohibited everywhere else on White Sands Missile Range. Wear comfortable clothes and good walking shoes, and bring a hat, as the southwestern sun can be intense.
