Castle Rock, Colorado
Moving to Castle Rock
The guide I wish someone had handed me: what it costs, where people live, how the schools work, who your utilities are, and what to do on your first weekend. Every number checked at the source, with our own photos.

I write a weekly newsletter about Castle Rock, which mostly means I spend my weeks driving around town eating things and climbing stairs so you don't have to. So when people email asking "should we move to Castle Rock?" I have opinions. This hub and the five guides under it are the long version: the cost of living from the Census, the school system from the district, the utilities from the Town, and the fun stuff from actually going. If a fact has a number, the source is listed at the bottom of the page.

Castle Rock at a Glance
The numbers, each with its year and its source.
Local tip: The Census and the Town both publish these numbers for free. If you see a moving site quoting a Castle Rock population of 85,000 or 90,000, it is guessing. The estimate the Census Bureau actually published for July 2025 is 83,815.
Why People Land Here
The short version of what I hear from readers who moved in the last few years.
The trails come up first, almost every time. The Town of Castle Rock manages 104 miles of them, and you can walk out of most neighborhoods onto one. Ridgeline Open Space connects The Meadows and Red Hawk to Miller Park by a pedestrian overpass, the East Plum Creek Trail runs 8.6 paved miles from Castle View High School down to Montaine, and in July 2026 the Town opened Lost Canyon Ranch, 716 acres with 15 miles of hiking trail, the largest open space purchase in its history. I hiked every open trail there the week it opened.
Then it is the schools (Douglas County School District, with an assigned neighborhood school for every address and open enrollment on top), the downtown (a real one, with a library, a museum, Festival Park and a couple of blocks of Wilcox and Perry Street that fill up on a Saturday), and the fact that a hospital, an outlet mall, a rec center and a 300-acre park with a 200-step staircase are all inside town limits.
And the growth is real, which is a good thing if you are arriving: the Census counted 73,158 people in 2020 and estimates 83,815 in 2025, and the restaurants and shops have kept pace. In the last year and a half we have covered new sushi, a reopened brewhouse turned proper kitchen, new owners at the downtown candy shop and a hospital system building an ER in Crystal Valley. You are not moving to a town that is finished.
