Westminster

North metro city between Denver and Boulder with Standley Lake, a new downtown on the old mall site and commuter rail to Union Station.

Aerial view of suburban buildings, a lake, and baseball fields with a distant skyline.

Westminster sits along US 36 about halfway between Denver and Boulder, split between Adams and Jefferson counties. It's an older city than most people expect, with roots in the late 1800s, but most of its neighborhoods were built from the 1960s onward as it grew north and west.

Homes in Westminster

South Westminster, around 72nd Avenue and Federal Boulevard, has the oldest homes. A little north, the castle-like Westminster University building from the early 1900s still stands on its hill near 83rd Avenue. The middle of the city, around Standley Lake and Hyland Hills, is mostly 1970s through 1990s two-story homes and ranches. North Westminster has newer neighborhoods such as Bradburn, built in a walkable, front-porch style, and the golf-course homes around Legacy Ridge. Downtown Westminster is adding apartments and condos.

Downtown Westminster

The city bought the old Westminster Mall site at US 36 and Sheridan Boulevard and is building a new downtown on its 105 acres, with apartments, restaurants, an Alamo Drafthouse cinema and a central park. Construction is still ongoing block by block.

Parks and things to do

Standley Lake Regional Park has boating, fishing, camping and trails, and bald eagles nest there in winter. The Butterfly Pavilion on 104th Avenue is an invertebrate zoo with a walk-through tropical butterfly conservatory, and in 2025 it agreed with the city to stay and expand in place. The city also runs an extensive trail system and several golf courses.

Getting around

The B Line commuter rail runs from Westminster Station at 71st Avenue and Federal Boulevard to Union Station in under 15 minutes. US 36 connects to Boulder and Denver, with bus service along it, and I-25 runs along the city's east side.
