Fort Collins sits at the base of the Rocky Mountain foothills along the Cache la Poudre River, and it carries the confident, grounded energy of a city that knows exactly what it is. Colorado State University anchors much of the city's identity as a public research institution and one of the state's largest employers, shaping a culture that values education, sustainability, and the outdoors. Old Town draws residents to its preserved historic streetscape and the Lincoln Center, while neighborhoods like Midtown, Fossil Creek, and Campus West each offer a distinct pace and personality.
The rental landscape here reflects that variety. Craftsman-style houses, newer suburban builds, townhome-style apartment communities, and historic loft conversions near Old Town give renters plenty of options depending on lifestyle. The city's craft brewing legacy, with long-established names like New Belgium and Odell Brewing Company rooted here for decades, speaks to Fort Collins' broader character.

The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students. Ratings are on a scale of 1 (below average) to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.
