TranslateOverview
Nunn is a small unincorporated community in Weld County, Colorado, situated on the high plains roughly 35 miles north of Greeley. It sits at an elevation of around 5,000 feet and is surrounded by wide-open grassland, wheat fields, and cattle ranches that define the northeastern Colorado landscape.
The community is modest in size — a few hundred residents at most — and retains the quiet character of a traditional agricultural settlement. There are no major tourist attractions, but travelers with an interest in the working rural West, big-sky scenery, or simply passing through on the way to Wyoming or the Pawnee National Grassland will find it a genuine, unhurried stop.
Nunn is best understood as a waypoint and a window into everyday plains life rather than a destination in its own right. Visitors should arrive with modest expectations and an appreciation for wide horizons and small-town authenticity.

What to Know Before You Arrive
- Services in Nunn are very limited. Fill up on fuel, cash, and supplies in Greeley or Fort Collins before heading out.
- There is no hospital in Nunn; the nearest substantial medical facilities are in Greeley.
- Cell coverage can be patchy on the surrounding plains — download offline maps before you go.
- Weather on the northeastern Colorado plains can change rapidly. Thunderstorms are common in late spring and summer; blizzards can occur from October through April. Check forecasts carefully.
- This is a working agricultural area. Respect private land and fencing; do not trespass on ranch property.
Getting There
By Car
The most practical way to reach Nunn is by personal vehicle. From Greeley, head north on US-85 (also called the Greeley-Nunn Highway) for approximately 35 miles. From Fort Collins, travel east on CO-14 and connect north via local roads — verify the best route with a mapping app. US-85 is a straightforward two-lane highway through open ranch land.
By Air
The nearest commercial airports are Denver International Airport (DEN), roughly 90 miles to the south, and the smaller Northern Colorado Regional Airport (FNL) near Loveland/Fort Collins, which is closer but serves limited routes. A rental car from either airport is essentially required.
Public Transit
There is no scheduled public transit service to Nunn. Intercity bus routes serve Greeley, but onward travel to Nunn would require a private vehicle or rideshare arrangement — verify availability locally.
Getting Around
A personal vehicle is the only reliable way to get around Nunn and the surrounding area. The community itself is small enough to walk across in minutes, but exploring the nearby grasslands, farms, and neighboring towns requires a car.
Roads in the area are mostly paved state and county highways, though some routes to ranches and grassland tracts are unpaved dirt or gravel. After heavy rain these roads can become muddy and difficult without high clearance. Check road conditions locally before venturing off the main highway.
Things to See & Do
Pawnee National Grassland
The most significant attraction in the broader area is the Pawnee National Grassland, managed by the U.S. Forest Service and located a short drive east and northeast of Nunn. It encompasses hundreds of thousands of acres of shortgrass prairie and is one of the premier birding destinations in Colorado, particularly for grassland species such as the mountain plover, McCown's longspur, and ferruginous hawk. The Pawnee Buttes — two distinctive sandstone formations rising from the plain — are a popular hiking destination within the grassland. Verify access roads and any seasonal closures with the U.S. Forest Service before visiting.
Stargazing
The lack of light pollution on the northeastern plains makes the area around Nunn excellent for amateur stargazing on clear nights. The Milky Way is often visible to the naked eye in summer months away from any town lights.
Scenic Driving
US-85 and the county roads branching off it offer a genuine plains driving experience — long sight lines, working ranches, grain elevators, and antelope sightings are common. This is a landscape that rewards slow, attentive travel rather than speed.
Food & Drink
Dining options within Nunn itself are extremely limited and can change. Verify locally whether any café or bar is currently operating before you rely on it for a meal.
For a reliable range of restaurants, grocery stores, and fast food, plan to eat in Greeley before or after your visit. Greeley has a broad selection of dining from national chains to locally owned restaurants reflecting the region's Hispanic and ranching heritage. Stocking a cooler with food and drinks before departing for the plains is a practical approach for a day trip.
Practical Information
Emergency Services
For emergencies anywhere in the United States, dial 911. The Weld County Sheriff's Office covers the Nunn area. The nearest hospital-level care is in Greeley — verify the exact facility with local authorities or your accommodation.
Money
ATMs and bank branches are not reliably available in Nunn. Withdraw cash and handle any banking needs in Greeley or Fort Collins before arriving.
Connectivity
Broadband internet and consistent cell service are not guaranteed in this rural area. Major US carriers (Verizon, AT&T) tend to have better rural coverage than smaller providers, but gaps still exist. Download maps and any needed information in advance.
Fuel
Fuel availability in and around Nunn is limited. Do not leave Greeley or the highway corridor with less than a half tank.
Safety
Nunn and the surrounding Weld County plains are generally safe for travelers. The primary risks are environmental and logistical rather than crime-related.
- Weather hazards: Severe thunderstorms, hail, and tornadoes occur on the Colorado plains, particularly May through July. Monitor weather alerts.
- Wildlife: Rattlesnakes are present in grassland areas; watch where you step, especially around rocks and brush. Pronghorn antelope and deer on roads create collision hazards at dawn and dusk.
- Isolation: If your vehicle breaks down on a remote county road, help may take time to arrive. Carry water, a phone charger, and basic supplies.
- Heat and sun: The high plains sun is intense. Use sunscreen, wear a hat, and carry ample water when exploring outdoors.
