What Travellers Say
Reviews Summary
Visitors consistently praise the Hanford B Reactor tour for its historical significance and the exceptional knowledge of the guides. The immersive experience of seeing the preserved reactor and learning about the Manhattan Project is highly recommended. Some note the tour's length and travel time, but most agree it's well worth the commitment for a unique glimpse into a pivotal moment in history.
"This was an amazing tour. 4 hours but 1 1/2 hours on the bus going there. The tour guide on the bus was great, and made the trip there and back to quickly giving facts about the area. The on site guides were amazing as well. They seemed to have all worked there at point and all seemed to have a strong understanding on the whole process. With the amount of information they shared it felt like I needed to take notes. Amazing what they did in 1943 before computers and how quickly they did it. Highly recommend, and you won't even glow after the tour!"

"Need to comeback during tour season. They have some exhibits here and staff is super friendly and knowledgeable, shared several stories about local history with the land, people and Hanford site. Gave several recommendations of things to see during the winter months as tours only run April-Fall."
Trypp Adams
"Well worth spending the time to take this unique tour - especially if you are interested in US history and/or technology. Very informative and well run. After the bus ride from the visitor's center and an intro talk, you are free to go through the facility. The docents are quite knowledgeable and happy to answer questions. But do it soon. I understand that after the 2024 season, they will pause the reactor tour for 2 or 3 years to perform upgrades."
