Download the Ventura County Map files from this page as one high-resolution A3 JPG ZIP. The package includes a general county map, a ranked city-distribution map, and a terrain-and-water map. The road view labels Oxnard, San Buenaventura (Ventura), Camarillo, Thousand Oaks, Simi Valley, Santa Paula, Fillmore, Ojai, US 101, Highway 126, Highway 33, and Highway 23. The water view adds the Santa Clara River, Ventura River, Sespe Creek, Piru Creek, Arroyo Simi River, Calleguas Creek, the Pacific coast, and the rugged mountain country that separates several of the county’s urban areas.
Ventura County is not one continuous city corridor. The largest developed areas occupy the coastal plain around Oxnard and Ventura, another cluster spreads through Camarillo, Thousand Oaks, Moorpark, and Simi Valley, and a long inland valley carries Santa Paula and Fillmore eastward along Highway 126. Ojai sits north of the coastal cities in a more enclosed mountain setting. The supplied maps are useful because roads, rivers, and relief all show the same basic pattern: broad lowlands are separated by ridges and narrow valleys.
Table of Contents
Oxnard, Ventura, and Camarillo form the most obvious coastal urban belt along US 101
Oxnard occupies the largest labeled urban area on the southwestern plain. San Buenaventura, commonly shown as Ventura, lies immediately to the northwest, and Camarillo continues the developed corridor to the east. US 101 is the easiest road to follow through this part of the county because it links the three areas before continuing toward the interior and neighboring counties.
Several other highways branch away from the coastal corridor. Highway 33 turns north from the Ventura side toward Ojai, while Highway 1 is visible closer to the coast south of Oxnard. East of Camarillo, the road pattern begins to split toward Thousand Oaks and Moorpark rather than remaining on a single shoreline route. This is why the western half is best read as a coastal plain connected to several inland valleys, not as one straight urban strip.
The general map is a regional orientation tool, not a live traffic map. It does not report congestion, closures, construction, wildfire detours, or current travel time. Use it to understand where cities and highways sit, then rely on current transportation information for an actual trip.
Highway 126 and the Santa Clara River define the long valley through Santa Paula and Fillmore
Santa Paula and Fillmore sit northeast of the coastal cities in a long inland corridor. Highway 126 runs through both communities and provides the clearest transportation reference for the valley. Santa Paula is closer to the coast and Ventura side, while Fillmore lies farther east toward the Los Angeles County boundary. The sequence is easy to recognize even on the simplified county map.
The terrain-and-water map shows the Santa Clara River following the same broad valley. The river does not duplicate Highway 126 exactly, but both use the low corridor between mountain blocks. Sespe Creek descends from the north and joins the central valley system, while Piru Creek occupies the eastern mountain side. Those waterways explain why Santa Paula and Fillmore sit in a distinct valley rather than merging into the Oxnard–Ventura coastal plain.
This water map is not a flood-hazard or river-stage product. It does not show levee condition, current flow, flood probability, or emergency routing. Its value is geographic: it makes the relationship among Santa Paula, Fillmore, Highway 126, the Santa Clara River, and the surrounding mountains much easier to see.
Thousand Oaks, Simi Valley, and Moorpark occupy a separate inland city cluster
Thousand Oaks and Simi Valley are the two large developed areas in the southeastern county. They are separated from the Oxnard–Ventura coast by hills and interior valleys, which is visible on both the road and hillshade maps. Highway 23 is a strong reference near Thousand Oaks and continues north toward the Moorpark side of the county.
Moorpark sits between the Thousand Oaks and Simi Valley areas but farther north. The city is small on the county-scale map compared with its larger neighbors, yet its position helps connect the southeastern cluster with the central interior. Simi Valley reaches close to the Los Angeles County boundary, while Thousand Oaks lies farther south and west in a different valley system.
The water map gives these two cities separate natural references. Arroyo Simi River follows the Simi Valley side, while Calleguas Creek is labeled farther southwest through another drainage. The distinction is useful because the southeastern county is not served by one single river corridor in the way Santa Paula and Fillmore are organized around the Santa Clara Valley.
The ranked city map reveals two large population clusters rather than one county center
The city-distribution map ranks six places: Oxnard, Simi Valley, Thousand Oaks, San Buenaventura (Ventura), Camarillo, and Moorpark. It is not a connector-distance graphic. No line between the symbols represents mileage or travel time. The map is designed to simplify the county and show where the six ranked cities sit relative to one another.
Oxnard, Ventura, and Camarillo occupy the southwest and coastal side, while Thousand Oaks and Simi Valley form a second group farther southeast. Moorpark sits north of that second group. The pattern makes the county’s urban geography easier to understand than a single population ranking would: large cities are divided by terrain and valleys rather than stacked around one central downtown.
The city index includes population figures, but those numbers belong to the source date used when the graphic was created. Readers who need the latest estimate or a specific census year should check the U.S. Census Bureau directly. On this page, the ranked city view is used for relative location and order only.
Ojai, the Ventura River, and Sespe Creek open into the rugged western and northern mountains
Ojai sits north of Ventura and the coastal plain in a more enclosed mountain setting. Highway 33 provides the clearest road reference from the coast into this area. The general map shows development thinning rapidly as the route moves north, while the terrain map replaces city labels with ridges, valleys, and streams.
The Ventura River is labeled from the Ojai side toward the coast. Farther north and east, Sespe Creek crosses a much broader mountain region. The northwestern portion also includes the Cuyama River and Alamo Creek near the upper county boundary. These waterways occupy separate valleys and are useful for dividing a large area that otherwise contains few major settlement labels.
The strongly shaded northern terrain should be read as general relief, not as precise elevation data. The map does not provide survey heights or engineering-grade slopes. It is useful because it shows how dramatically the landscape changes after leaving the coastal plain and central valley roads.
The Pacific coast, Arroyo Simi River, and Calleguas Creek define very different southern settings
The Pacific Ocean fills the southern edge of the terrain-and-water map and provides the most obvious physical boundary on the county’s coastal side. The Ventura River and Santa Clara River reach the lower coastal area from inland valleys. Their positions help explain why the Oxnard–Ventura plain looks much broader and flatter than the mountain interiors to the north.
Farther southeast, Arroyo Simi River follows the Simi Valley side while Calleguas Creek occupies another drainage closer to the Thousand Oaks and Camarillo region. These watercourses do not form one continuous river. Reading them separately prevents the southeastern city cluster from being mistaken for an extension of the Santa Clara River valley.
Labels such as Castaic Lake Lagoon, Malibu Lagoon, and Marina del Rey appear outside the county boundary as regional references on the preview. They should not be described as internal Ventura County water features. The article therefore focuses on the rivers, creeks, and ocean edge that are actually shown within the county outline.
Use the road map for urban corridors and the water map for valleys, creeks, and mountain relief
Choose the general county map when you need Oxnard, Ventura, Camarillo, Santa Paula, Fillmore, Thousand Oaks, Simi Valley, Ojai, US 101, Highway 126, Highway 33, or Highway 23. It provides the clearest view of cities, roads, and the county outline. Use the ranked city map when you want a simpler comparison of the six major cities without the extra highway detail.
Choose the terrain-and-water map for the Santa Clara River, Ventura River, Sespe Creek, Piru Creek, Arroyo Simi River, Calleguas Creek, the Pacific coast, and the mountain setting. A useful method is to locate a city first and then change maps. Find Santa Paula and Highway 126 before following the Santa Clara River, or find Simi Valley first and then compare the Arroyo Simi drainage.
These files are general-reference maps. They should not be used for legal parcel boundaries, flood risk, live traffic, wildfire evacuation, water quality, streamflow, navigation, engineering design, or precise elevation measurement. For classroom work, reports, presentations, broad trip orientation, and personal printing, the three views provide a practical overview of how Ventura County’s cities, highways, river valleys, coast, and mountains fit together.
Frequently Asked Questions
Does the Ventura County city map show distances between the six ranked cities?
No. This is a ranked city-distribution map for Oxnard, Simi Valley, Thousand Oaks, San Buenaventura (Ventura), Camarillo, and Moorpark. It does not connect the cities with straight-line or driving-distance measurements. Use a current mapping service when actual travel distance is needed.
Which part of Ventura County is easiest to understand from the Santa Clara River?
The river is especially useful for reading the inland valley around Santa Paula and Fillmore. Locate Highway 126 and the two communities on the general map, then switch to the water map to see the Santa Clara River running through the same broad valley. The map is a geographic reference and does not show flood risk or current river stage.
