This Larimer County map page lets you download the same maps as high-resolution JPG files in a ZIP archive below. Larimer County stretches from the busy Front Range communities around Fort Collins and Loveland into a much higher western landscape of mountain valleys, streams, and scattered settlements. The supplied county map makes that contrast easy to see: most of the named cities cluster along the eastern side, while Estes Park and Red Feather Lakes sit well apart from that urban group. I-25, US 287, US 34, US 36, and CO 14 provide the main road references on the map, and separate city, water-and-terrain, and elevation views add detail.
A useful way to orient yourself is to start with Fort Collins and then look west. Around Fort Collins, Loveland, Timnath, Wellington, Berthoud, and nearby communities, roads and place names are relatively dense. Farther west, the map becomes dominated by valleys, ridges, and drainage lines instead of large urban areas. The water map reinforces the same pattern through the Cache la Poudre and Big Thompson river systems, while the elevation map shows a sharp rise from the lower eastern edge to the high country near the western side of the county.

The county map shows two very different sides of Larimer County
The eastern third of the map is the easiest place to identify the county’s main population centers. Fort Collins sits near the northeast portion of the county, with Loveland farther south and Wellington to the north. Timnath appears east of Fort Collins, while Berthoud and Johnstown are near the southeastern side. Windsor is also shown close to the eastern boundary. These places form a much tighter group than the communities shown in the mountain half of the county.
West of that cluster, the spacing changes quickly. Estes Park is shown in the southwest mountain area, connected to the lower Front Range by US 34 and US 36. Red Feather Lakes appears much farther north in the interior high country. CO 14 crosses the northern part of Larimer County and provides another strong reference for finding the mountain side of the map. The county boundary extends far beyond the Fort Collins-Loveland urban area, so the full county view is helpful when a search result or address gives only the county name without a nearby city.
I-25 is the clearest north-south road reference on the eastern side. US 287 also passes through the Fort Collins area, while US 34 runs west from the Loveland side toward the mountains. US 36 approaches Estes Park from the southeast, and CO 14 cuts across the northern portion of the county. Those roads help establish location, but the map is not intended to replace current navigation, closure, or winter-driving information. For an actual trip, current road conditions should be checked separately.
Fort Collins and Loveland anchor the eastern city cluster
The city index strips away much of the background detail and makes the eastern concentration especially obvious. It identifies Fort Collins, Loveland, Johnstown, Wellington, Timnath, and Berthoud as the six major cities in the supplied view. Fort Collins is the largest center shown, with Loveland forming the other major urban anchor farther south. Wellington and Timnath sit close to Fort Collins on different sides, while Berthoud and Johnstown help define the southern and southeastern edge of the group.
What matters most on this map is not the precise ranking but the distribution. Nearly the entire western half lacks comparable major-city markers. That makes the eastern side look compact and connected, while the mountain side appears broad and lightly settled. Someone comparing Fort Collins with Loveland or Wellington can use this simplified map without the visual distraction of every road and stream. For Estes Park, Red Feather Lakes, or a mountain corridor, the full county map is more useful because those places fall outside the main city cluster shown here.
The county’s own overview provides useful context for this pattern. Larimer County identifies Fort Collins as the county seat and notes that the county reaches the Continental Divide and includes mountain communities as well as parts of Rocky Mountain National Park. The same official page lists Estes Park, Fort Collins, Loveland, Timnath, and Wellington among municipalities fully within the county, with Berthoud, Johnstown, and Windsor partly within it. That background matches the broad contrast visible on the supplied maps: dense settlement in the east and a far larger mountain landscape to the west.
The Poudre and Big Thompson systems organize much of the water map
The terrain-and-water map adds a layer that the road map cannot show. In the northern half, the Laramie River runs through the high country, while the North Fork Cache la Poudre River and Cache la Poudre River cross mountain valleys toward the eastern side of the county. Seaman Reservoir is labeled northwest of Fort Collins. Closer to the plains, the map also marks Windsor Reservoir, Terry Lake, and Cobb Lake.
Farther south, the North Fork Big Thompson River and Big Thompson River cut through a different set of valleys before heading toward the Loveland side of the county. Boyd Lake appears near the eastern edge, and Carter Lake Reservoir is labeled in the south-central area. The Little Thompson River follows the lower portion of the county. Together, these named features show that Larimer County is not organized around one single river. Several mountain watersheds descend toward the plains through separate valleys.
The shaded relief behind the blue water lines is useful because many streams follow narrow mountain valleys that are hard to interpret on a plain road map. The drainage pattern becomes more intricate in the west and simpler as the major rivers approach the lower eastern terrain. This is a general reference map, not a flood-hazard, property-boundary, reservoir-operation, or boating-navigation product. Anyone planning recreation at a reservoir or along a river should use current information from Larimer County Natural Resources or the appropriate managing agency.
Elevation rises from about 1,456 meters to more than 4,100 meters
The elevation map reports an actual county range of roughly 1,456 to 4,112 meters, with a mean elevation of about 2,361 meters. The lowest colors cover much of the eastern plains around the main urban corridor. Moving west, the surface changes through progressively higher bands, and the western and southwestern portions contain extensive high mountain terrain. The relief is especially strong around the deep valleys and ridges west of the Front Range cities.
This view explains why a short straight-line distance on the county map can cross very different terrain. Fort Collins and Loveland occupy comparatively low ground, while the Estes Park area is surrounded by much higher relief. Red Feather Lakes is also set within a more rugged landscape than the eastern city cluster. US 34, US 36, and CO 14 therefore pass through very different elevation settings than I-25 on the plains. The map does not provide road grades, but it clearly shows where the broad change from lowland to high country occurs.
The elevation surface is intended for county-scale comparison rather than site-specific measurement. It is useful for locating broad mountain fronts, high ridges, and lower valleys, but it should not be treated as survey-grade elevation for construction, engineering, or parcel work. For technical elevation work, use the original USGS 3D Elevation Program data or a professional survey. For ordinary map reading, however, placing this elevation view beside the county and water maps makes Larimer County’s east-west contrast much easier to understand.
Estes Park and the western high country add a second geographic focus
Larimer County is often associated with Fort Collins because that is the county seat and largest city shown here, but the western side is equally important to the county’s geography. Estes Park occupies a mountain valley near the southwestern portion of the map and serves as a familiar reference point for the high country. The National Park Service lists its Rocky Mountain National Park mailing address in Estes Park, and Larimer County’s official overview notes that the county includes part of the park and reaches the Continental Divide.
Red Feather Lakes provides a different reference farther north. It is separated from the eastern cities by a broad area of foothills and mountain terrain, and its position is easier to understand when the county, water, and elevation maps are viewed together. The supplied maps do not draw national park, national forest, recreation-area, or land-ownership boundaries in detail. If the goal is to plan a park visit or determine public-land access, use the appropriate National Park Service, Forest Service, or Larimer County recreation map after locating the general area here.
Choose the map by the question you need to answer
For a quick comparison of Fort Collins, Loveland, Wellington, Timnath, Berthoud, and Johnstown, the city map is the cleanest choice. The county map is better when road numbers, Estes Park, Red Feather Lakes, and the county boundary matter. The terrain-and-water map is best for finding the Cache la Poudre River, Big Thompson River, major tributaries, and labeled reservoirs. The elevation map is most useful when you want to see how rapidly the county rises from the eastern plains into the western mountains.

Frequently Asked Questions
Which map is best for comparing Fort Collins and Estes Park?
Use the county overview first because it shows both places together with US 34, US 36, and the wider road network. Add the elevation map if you also want to compare the lower Fort Collins area with the much higher terrain around Estes Park.
Where can I find the Cache la Poudre and Big Thompson rivers?
Both are labeled on the terrain-and-water map. The Cache la Poudre system occupies the northern and central part of the county, while the Big Thompson system crosses the southern mountain area toward Loveland. The map is for general location reference rather than flood, legal, or navigation use.
Can the elevation map be used for engineering or property surveys?
No. It is a generalized county-scale surface designed to compare broad elevation differences. Engineering, construction, and survey work should use the underlying authoritative elevation data and, where required, professional field measurements.
