Denver sits where the Great Plains meet the Rockies — a city built on gold rush ambitions, cattle trade, and Cold War military infrastructure, each era leaving behind forgotten structures in the surrounding landscape. From a 19th-century amusement park theater that survived while everything around it was demolished, to Cold War missile silos buried under the prairie 45 minutes east of downtown, Denver offers urban exploration with serious historical range. Here are 5 of the best abandoned places in Denver, selected from our Abandoned Places Map USA — 5,000+ GPS locations across the United States.
Why Denver Is a Hidden Gem for Abandoned Buildings & Urban Exploration
Denver's urbex landscape spans three distinct eras — the Victorian mining boom that built ornate theaters and grand hotels, the mid-20th century Cold War that ringed the city with missile infrastructure, and the post-industrial decline that left Rust Belt-style warehouses and factories along the South Platte River corridor. Add in the Colorado ghost towns within two hours of the city and Denver becomes one of the best urbex base camps in the American West.
1. Historic Elitch Theatre – Last Surviving Structure of Denver's 1890 Elitch Gardens, Still Standing at 38th & Tennyson (Known Location)
When John and Mary Elitch opened their zoological gardens on May 1, 1890, Denver was still a frontier city riding the silver boom. Elitch Gardens became Colorado's first zoo, first botanic garden, first children's museum, and first symphony orchestra venue — one of the most culturally significant sites in Denver history. When the amusement park moved to a new location in 1994, almost everything on the original site was demolished. The Historic Elitch Theatre alone survived — a stunning Victorian structure at 38th and Tennyson that has sat in various states of restoration and semi-abandonment ever since, holding guided tours and occasional events while its full restoration remains unfinished. One of the most important urbex preservation sites in the American West.

2. Titan I Missile Silo, Deer Trail – Decommissioned 1965, Subterranean Labyrinth 45 Minutes East of Denver (Known Location)
One of six Titan I ICBM sites built around Denver between 1960 and 1965 to protect the region from Soviet nuclear attack — each capable of launching a nuclear-tipped intercontinental ballistic missile from underground silos. When advances in missile technology made the Titan I obsolete in 1965, the sites were decommissioned and handed over to various owners. The Deer Trail complex, 45 minutes east of Denver on the Great Plains, has become one of the most-documented underground urbex sites in Colorado — metal access gates at the entry, a subterranean labyrinth of tunnels, launch silos and crew quarters stretching deep into the prairie. A genuinely remarkable piece of Cold War infrastructure open to determined explorers.

3. Abandoned South Platte River Industrial Complex – Late Victorian Brick Mills with Millrace Still Visible, Denver West Side (Exclusively on Our Map)
A late Victorian brick industrial complex along the South Platte River — the millrace channel that once powered the machinery still visible alongside the building, original brick construction with decorative corbelling typical of 1890s Denver industrial architecture and the loading bays with iron hardware intact. Denver's west side industrial corridor developed rapidly in the 1880s-1900s and has never been fully redeveloped; this complex is one of the most intact surviving examples of that era. Exact location available on our Abandoned Places Map USA.
4. Abandoned Prairie Farmstead – 1920s Homestead with Collapsed Barn and Root Cellar Intact, Adams County (Exclusively on Our Map)
A 1920s homestead on the flat Adams County prairie east of Denver — main farmhouse structurally intact with original windows and door frames, a collapsed timber barn whose beams form a photogenic tangle against the Colorado sky and a stone root cellar with its arched entrance still perfectly preserved. The eastern Denver metro's agricultural past is rapidly being erased by suburban expansion; this compound sits in the shrinking belt of original prairie farmland between the city and the Kansas border. Exact location available on our Abandoned Places Map USA.
5. Forgotten Rocky Mountain Mining Support Town – 1890s Assay Office and General Store Still Standing, Clear Creek County (Exclusively on Our Map)
A support community from Colorado's 1890s silver and gold mining era — the assay office where miners brought ore samples for testing still has its original counter and scales, the general store retains its wooden shelving and the surrounding cabins range from structurally intact to slowly collapsing into the mountain slope. Colorado has dozens of mining ghost towns; this one sits off the main tourist circuits with far less foot traffic than the well-known sites. Exact location available on our Abandoned Places Map USA.
Safety Tips for Urban Exploration in Denver
- Altitude: Denver sits at 5,280 feet — mountain sites can be significantly higher; acclimatize before extended exploration and watch for altitude sickness symptoms
- Underground sites: missile silos and mine tunnels require oxygen monitoring and proper lighting — never enter underground spaces without appropriate equipment
- Never explore alone — always bring at least one other person and let someone know your location
The urbex code applies everywhere: "Take nothing but photographs, leave nothing but footprints."
