Los Alamos County, New Mexico
Los Alamos County is high up in the Jemez Mountains of north-central New Mexico. It’s small. In fact, it’s the smallest county in New Mexico by area. But don’t let its size fool you.
This place has brains. Los Alamos National Laboratory calls it home. That’s where they developed the atomic bomb during World War II. The town feels like a college campus. Scientists everywhere.
The scenery is stunning. Mesas, canyons, and forests surround you. Bandelier National Monument is nearby. Ancient cliff dwellings are carved into the rock. It’s mind-blowing. Outdoor recreation is big. Hiking, mountain biking, skiing… it’s all here.
