Castle Rock at a glance
I grew up in Castle Rock, so this is the guide I wish every relocating buyer had before their first visit. The town sits on I-25 about halfway between Denver and Colorado Springs, under the flat-topped butte it is named for. It has a real historic downtown, a big trail and open-space system, and a mix of established neighborhoods, master-planned communities and acreage.
Sources: U.S. Census Bureau ACS 2020–2024 5-year estimates; OpenStreetMap routing from Festival Park; NOAA 1991–2020 climate normals. The Town of Castle Rock’s own Parks and Recreation materials describe more than 85,000 residents today, so the Census survey figure runs behind current growth.
Key takeaways
- Castle Rock is in Douglas County, with most public schools in Douglas County School District.
- Plan on I-25 for nearly every commute; there is no light rail in town.
- Check every address for a metro district before you write an offer; it changes the tax bill.
- The town manages 104 miles of trails, 25 parks and more than 4,000 acres of open space.
Cost of living and home prices
I only use published numbers here, and I tell you where each one comes from. The U.S. Census Bureau’s American Community Survey (2020–2024 5-year estimates) reports for the Town of Castle Rock:
| Measure | Castle Rock | Denver (for comparison) |
|---|---|---|
| Median value, owner-occupied homes | $652,900 | $616,000 |
| Median household income | $145,197 | $94,718 |
| Population | 79,123 | 718,877 |
Source: U.S. Census Bureau, ACS 2020–2024 5-year estimates, tables B25077 (median home value), B19013 (median household income) and B01003 (population), released by the Census Bureau in early 2026. These are survey estimates with margins of error (for Castle Rock, about ±$8,994 on home value and ±$7,924 on income).
The Census median value is what owners estimate their homes are worth, based on survey responses collected over five years (2020–2024). It is useful for comparing towns, but it is not today’s list price. Prices also vary a lot by neighborhood, from historic homes near downtown to newer master-planned homes and acreage on the edges of town. When you are ready, I’ll pull recent closed sales for the exact neighborhoods and price range you are considering.
Beyond the mortgage, budget for HOA dues (common in newer communities), any metro district levy, utilities and the property tax bill described below.
Property taxes and metro districts
Colorado property taxes follow one formula: actual value × assessment rate = assessed value, then assessed value × mill levy = tax. For tax year 2026, Douglas County lists residential assessment rates of 7.05% for school districts and 6.8% for other local governments, after a legislative 10% reduction of the first $700,000 of actual value. Mill levies are set each December by the taxing authorities for that address, such as the school district, town, county, fire district and any special districts.
Metro districts matter in Castle Rock
Many newer Castle Rock neighborhoods were built with metropolitan districts that fund roads, water lines, parks and trails. Each one adds its own mill levy, so two similar homes a mile apart can carry very different tax bills. Before you offer, look up the parcel on the Douglas County Assessor site to see every taxing district, and read the district’s disclosure. My metro districts guide walks through it step by step.
Commutes to Denver, DTC and Colorado Springs
Driving distances below start at Festival Park in downtown Castle Rock. Times are traffic-free estimates from OpenStreetMap routing; rush hour on I-25 is longer, so test the drive at the hour you would really commute.
| Destination | Distance | No-traffic estimate |
|---|---|---|
| Lone Tree (closest light rail area) | about 14 mi | about 20 min |
| Denver Tech Center (DTC) | about 19 mi | about 25 min |
| Downtown Denver (Union Station) | about 30 mi | about 40 min |
| Downtown Colorado Springs | about 39 mi | about 45 min |
| Denver International Airport | about 46 mi | about 55 min |
| Colorado Springs Airport | about 52 mi | about 65 min |
Castle Rock is outside RTD’s light rail network, so most residents drive. Households with one partner working in the DTC and another in Colorado Springs often like Castle Rock precisely because it splits the difference.
Weather at 6,000+ feet
NOAA’s 1991–2020 climate normals for the Castle Rock station (elevation about 6,185 feet) show:
Snow mostly falls from November through April, and the snowiest months on average are February and March. Summer afternoons bring the most rain. If you are moving from coastal California or the Texas Gulf, expect drier air, stronger sun at altitude and big day-to-night temperature swings; plan for good tires and a snow shovel.

Shopping, dining and downtown
Downtown Castle Rock centers on Wilcox and Perry streets and Festival Park, where many community events happen. The Downtown Merchants Association and the Castle Rock Chamber run seasonal events, including Oktoberfest, Artfest and the Starlighting. For everyday shopping, the Promenade at Castle Rock along I-25 and Founders Parkway has big-box stores and restaurants, and the Outlets at Castle Rock on Factory Shops Boulevard draw shoppers from across the Front Range. Lone Tree’s Park Meadows area is a short drive north.
Schools
Most public schools in Castle Rock belong to Douglas County School District. Schools that serve Castle Rock include:
- High schools: Castle View High School and Douglas County High School
- Middle schools: Castle Rock Middle School and Mesa Middle School

Tips for out-of-state buyers
- Start with video. I can walk homes with you live on FaceTime or Zoom and record neighborhood drives so you can narrow the list before you fly in.
- Get pre-approved early. A Colorado-licensed lender can explain local costs, including HOA and metro district payments.
- Learn the Colorado contract. Colorado uses state-approved forms with firm dates for inspection, appraisal and loan. See my contract deadlines guide.
- Check taxes by parcel. Use the Douglas County Assessor to see every taxing district for an address.
- Test the commute. Drive I-25 at your real commute hour on your visit.
- Plan the closing. Ask your title company about remote or mail-away signing if you can’t be here.
