Description: Detailed large map of Utah State, USA showing cities, towns, county formations, roads highway, US highways and State routes.
Utah map (USA). This map lays out every county and its county seat, from Salt Lake City in the north down to St. George in the south, along with the state's major cities in between. County lines, city locations, and a light interstate layer are all here together, giving you fast, accurate orientation without extra clutter.
Borders and waters at a glance: Follow the outline of the state and you'll cross four neighbors. Idaho sits along the northern edge, meeting Box Elder, Cache, and Rich counties. Swing into the northeast corner and Wyoming takes over, bordering Rich, Summit, Daggett, and Uintah. The long eastern side runs against Colorado, through Daggett, Uintah, Grand, and San Juan counties, and the southern edge meets Arizona along Washington, Kane, and San Juan, with San Juan reaching one step further to touch New Mexico at the Four Corners point. Nevada then runs the entire western side, past Box Elder, Tooele, Juab, Millard, Beaver, Iron, and Washington counties. Inside those borders, the map lays out all 29 counties, with the Colorado, Green, and Sevier rivers acting as the main orientation lines through the interior and the Great Salt Lake anchoring the northern basin. A few light interstate cues (I-15, I-80, I-70) help you find the four big metro anchors: Salt Lake City in Salt Lake County, Provo in Utah County, Ogden in Weber County, and St. George in Washington County.
Begin at the Idaho line. Box Elder County lists Brigham City as the county seat, filling the northwest corner between the Great Salt Lake and Nevada, with farm towns like Tremonton and Garland near the Bear River Migratory Bird Refuge. East across the Wellsville Mountains, Cache County shows Logan as its seat, a tight university valley bordered by the Bear River Range, with North Logan, Hyde Park, and Hyrum clustered along the valley floor. Rich County, seat Randolph, is a high-country county wrapped around the Utah shoreline of Bear Lake, with resort cabins around Garden City dotting the lakeshore.
South along the lake, Weber County centers on Ogden, stretching from Great Salt Lake wetlands to the Wasatch foothills through Roy, Riverdale, and North Ogden. Davis County, seat Farmington, is a narrow shoreline strip holding Layton, Kaysville, Syracuse, Clearfield, and Bountiful, with Antelope Island reaching into the lake. Salt Lake County is the state capital anchor, seat Salt Lake City, with closely packed suburbs including West Valley City, West Jordan, Sandy, South Jordan, Draper, Murray, Taylorsville, Riverton, Herriman, and Midvale.
West of Salt Lake, Tooele County carries the seat Tooele against the Oquirrh Mountains and the Great Salt Lake Desert, with Grantsville and Stockton near the basin and the county running clear to the Nevada line. East of Ogden Canyon, small Morgan County, seat Morgan, sits as a mountain crossroads between the Wasatch Front and the Uinta foothills, with the Weber River looping through.
Summit County, seat Coalville, holds the resort towns of Park City and Kamas, with mountain drainages stepping toward Wyoming along I-80. Wasatch County, seat Heber City, fills the Heber Valley between the Wasatch Range and Jordanelle Reservoir, with Midway sharing the valley floor and US-40 running toward Duchesne and Uintah counties.
Utah County, seat Provo, stretches from Lehi at the Point of the Mountain south through Orem, Springville, Spanish Fork, Payson, Santaquin, Eagle Mountain, and Saratoga Springs along the shore of Utah Lake, with I-15 tracing the populated western edge beneath the Wasatch peaks.
East over the Wasatch Range, Duchesne County, seat Duchesne, opens into oil-field country with Roosevelt nearby and US-40 as the long valley route. Uintah County, seat Vernal, sits on the Colorado Plateau's edge near dinosaur-rich formations and the Green River corridor, with Naples close by. Daggett County, seat Manila, is Utah's least populous county, hugging Flaming Gorge Reservoir on the Wyoming line with Dutch John as its other small town.
South of the basin, Carbon County, seat Price, grew up around coal, with Helper and Wellington set between the Wasatch Plateau and the Book Cliffs along US-191. Emery County, seat Castle Dale, lies west of the San Rafael Swell with Huntington, Ferron, and the town of Green River along its valleys.
Sanpete County, seat Manti, is a long north-south agricultural valley through Ephraim, Mount Pleasant, Fairview, and Gunnison between the Wasatch Plateau and Utah County. Juab County, seat Nephi, spans the Tintic Range and Juab Valley through Eureka and Mona, reaching far west toward the Snake Valley.
Millard County, seat Fillmore, the former territorial capital, anchors a wide desert county with Delta and the Sevier Lake basin, bordering Nevada on the west. Beaver County, seat Beaver, sits on the central north-south corridor between the Mineral and Tushar Mountains, with Milford to the west.
Sevier County, seat Richfield, is a service hub on the Sevier River near Monroe and Salina, with I-70 quietly crossing the county. Piute County, seat Junction, is one of Utah's smallest counties by population, with Marysvale near the Paiute ATV trail network. Wayne County, seat Loa, spans the Fremont River through Torrey and Bicknell into the canyons of Capitol Reef country.
Garfield County, seat Panguitch, is a vast slice of the Colorado Plateau taking in Escalante country, Boulder, and Bryce Canyon's Paunsaugunt Plateau. Kane County, seat Kanab, sits on the Arizona line as the classic red-rock base, with the Grand Staircase stepping toward Lake Powell.
Washington County, seat St. George, is Utah's warm southwest corner along the Virgin River, with Hurricane, Washington City, and Santa Clara near the Arizona and Nevada lines. Iron County, seat Parowan, holds Cedar City as its largest city under the Markagunt Plateau.
San Juan County, seat Monticello, is Utah's southeastern giant, touching Arizona, Colorado, and New Mexico at the Four Corners, with Blanding, Bluff, and the Monument Valley communities along the San Juan River. Grand County, seat Moab, sits along the Colorado River, a red-rock gateway to Arches and Canyonlands with US-191 and US-128 for gentle orientation.
Because every county block is colored and every county seat is printed in a consistent symbol, the eye can answer everyday questions quickly: Which county is Provo in? Utah. Where does Ogden sit? Weber, north of the Great Salt Lake. Which seat serves Flaming Gorge country? Manila in Daggett. What is the seat in the far southeast corner? Monticello in San Juan. Where is Cedar City relative to St. George? North across Iron from Washington. Where is Park City relative to Salt Lake City? East across Summit from Salt Lake. That is the power of this detailed map for both residents and visitors: counties first, with just enough network to anchor direction.
Three rivers and one great lake do most of the orientation work on this page. The Colorado River curves through the far southeast past Moab in Grand County. The Green River flows south through the Uinta Basin and canyon country before joining the Colorado. The Sevier River drains the central plateaus past Richfield and Salina. The Great Salt Lake anchors the northern basin along Box Elder, Weber, Davis, Salt Lake, and Tooele counties. Keep these four in mind and any county on the map is easy to place.
Road-light orientation: The road layer here stays deliberately thin, just enough to get your bearings. I-15 runs the full length of the Wasatch Front, from St. George up to the Idaho line. I-80 crosses the north, tracing the Nevada line through Salt Lake City to Wyoming. I-70 cuts through the center, from Cove Fort past Salina and Green River to the Colorado line, one of the longest interstate stretches in the country without a single service exit. US-40 covers the Heber-Duchesne-Vernal corridor to the northeast, and US-191 threads Price-Moab-Blanding through canyon country to the southeast. None of these lines are meant for turn-by-turn navigation; they're county-placement cues only, so look at the map itself for the real picture.
Every one of Utah's 29 counties and its seat, in alphabetical order: Beaver County (Beaver), Box Elder County (Brigham City), Cache County (Logan), Carbon County (Price), Daggett County (Manila), Davis County (Farmington), Duchesne County (Duchesne), Emery County (Castle Dale), Garfield County (Panguitch), Grand County (Moab), Iron County (Parowan), Juab County (Nephi), Kane County (Kanab), Millard County (Fillmore), Morgan County (Morgan), Piute County (Junction), Rich County (Randolph), Salt Lake County (Salt Lake City), San Juan County (Monticello), Sanpete County (Manti), Sevier County (Richfield), Summit County (Coalville), Tooele County (Tooele), Uintah County (Vernal), Utah County (Provo), Wasatch County (Heber City), Washington County (St. George), Wayne County (Loa), and Weber County (Ogden).
Utah borders Idaho to the north, Wyoming to the northeast, Colorado to the east, Arizona to the south, and Nevada along the entire west side, with a single Four Corners point touching New Mexico in the far southeast corner of San Juan County. The state holds 29 counties. San Juan County is the largest by land area at about 7,820 square miles, while Davis County is the smallest at about 299 square miles. Salt Lake County is the most populous at roughly 1,220,916 residents, and Daggett County is the least populous at roughly 934 residents. Salt Lake, Weber, Utah, Tooele, Iron, and Sanpete counties share the title of oldest, all organized in 1850 under the provisional State of Deseret before Utah became a federal territory in 1851. Utah covers about 84,897 square miles in total, with about 82,144 square miles of land. The capital, Salt Lake City, sits in Salt Lake County along the Wasatch Front, and the state's major metros run from Ogden through Salt Lake City and Provo-Orem to St. George in the southwest corner. Landscape-wise, the state moves from the Great Salt Lake basin and Wasatch Front outward through the Uinta Basin and Wasatch Plateau in the east, the Basin and Range deserts in the west, and the high plateaus and canyon country of the Colorado Plateau in the south.
Utah's ten largest cities by current population are Salt Lake City (about 222,706, Salt Lake County), West Valley City (about 137,047, Salt Lake County), West Jordan (about 116,737, Salt Lake County), Provo (about 114,523, Utah County), St. George (about 111,344, Washington County), Lehi (about 99,366, Utah County), Orem (about 94,699, Utah County), Sandy (about 91,360, Salt Lake County), Ogden (about 89,987, Weber County), and South Jordan (about 89,666, Salt Lake County). Salt Lake City anchors state government, finance, and the University of Utah's research and health sciences complex. Utah County's Silicon Slopes corridor around Lehi and American Fork has grown into one of the country's fastest-growing tech hubs, home to companies like Qualtrics and Ancestry. Ogden's Weber County keeps a strong manufacturing and outdoor-gear base, and Park City in Summit County anchors much of the state's ski and film-festival economy. Mining and energy still matter in Carbon and Emery counties' coal country and the Uinta Basin's oil fields around Vernal. Agriculture concentrates in the irrigated valleys of Cache, Sanpete, and Box Elder counties, with dairy, hay, and cattle leading production. With no coastline, Utah's water commerce is limited to reservoir and lake recreation rather than shipping.
Utah's cultural identity is closely tied to its pioneer settlement and outdoor landscape. Salt Lake City's Temple Square and the This Is the Place Heritage Park mark the 1847 arrival of Mormon pioneers into the Salt Lake Valley, an event still celebrated statewide each July as Pioneer Day. The state's ski industry runs through the Wasatch Front counties, with resorts at Park City and Deer Valley in Summit County and Alta, Snowbird, and Brighton up the canyons from Salt Lake County, a legacy of hosting the 2002 Winter Olympics. Park City also hosts the Sundance Film Festival each January, drawing independent filmmakers from around the world. Utah's national parks make outdoor recreation and canyon-country tourism central to the state's identity, including Zion in Washington County, Bryce Canyon in Garfield County, Capitol Reef in Wayne County, Arches and Canyonlands near Moab in Grand County, and the Monument Valley area of San Juan County. Higher education is spread across the map too, with the University of Utah and Westminster University in Salt Lake City, Brigham Young University in Provo (Utah County), Utah State University in Logan (Cache County), and Southern Utah University in Cedar City (Iron County).
On this map, Kings Peak (Uinta Mountains, Duchesne County) and the Colorado, Green, and Sevier rivers double as landmarks for finding counties quickly. For elevation, terrain, watersheds, and land-cover detail, see our Physical Map of Utah.
Utah has a mostly arid to semi-arid climate, with hot, dry summers and mild winters in the low deserts and much colder, snowier conditions across the Wasatch Front and the mountain counties. For a full seasonal and biome breakdown, see our Physical Map of Utah.
North-south travel runs mainly on I-15, threading the entire Wasatch Front from the St. George area to the Idaho line. East-west travel splits into two corridors: I-80 crosses the north from the Nevada line through Salt Lake City to Wyoming, while I-70 begins near Cove Fort south of Provo and cuts across the center of the state to the Colorado line. US-40 and US-191 extend the grid into the Uinta Basin and canyon country. Keep in mind that ZIP codes do not follow county lines in Utah, so a single ZIP code can span two counties. Always confirm the county name directly from the map or index rather than assuming it from a ZIP prefix.
Use this as a quick index. Every line lists the county with its county seat (and a familiar city when the map labels one). Short cues mention river, border, or gentle corridor context only.
