Welcome to the Los Alamos County government website - a gateway to information and services within and around Los Alamos County. Whether you are a citizen, business, or visitor, we designed this site to help you quickly and easily locate information and engage with us. Still looking for what you need? Email us at lacmanager@lacnm.us. **About the community** Comprising a little more than 19,000 residents, we are two small communities in one County - Los Alamos townsite and White Rock. We are also home to one of the National Nuclear Security Administration's laboratories - Los Alamos National Laboratory. **Community life** Community life features small-town living with friendly neighbors, low crime, and a nationally ranked public school district. It is also a community that seamlessly blends impressive culture and history with spectacular outdoor beauty and adventure. Residents and visitors alike can explore the 200+ miles of developed hiking and biking trails, enjoy summer and winter recreation at the local Pajarito Mountain ski area, and play high-altitude sports at the local Golf Course, the outdoor NHL regulation Ice Rink and the Olympic-sized Aquatic Center. **Gateway to three national parks** Did we mention that we are Gateway to Three National Parks, with the Manhattan Project National Historical Park located in downtown Los Alamos, Bandelier National Monument bordering the Los Alamos National Laboratory on the south side of the County, and the Valles Caldera National Preserve up the road in the Jemez Mountains on the west side of the County?
