Hilmar’s cheese visitor center is the easy introduction. The fuller story reaches back to Swedish settlement, a railway that moved the town’s center, and dairy families who built a business around their Jersey cows’ milk. Church history, school traditions and Azorean culture add reasons to look beyond a cheese purchase.

Dairy country south of Turlock
Hilmar is an unincorporated community in Merced County, south of Turlock. Lander Avenue, also Highway 165, is its main commercial corridor. A county planning description places the community north of the Merced River, surrounded by farmland, dairies, ranches and orchards. “Hilmar-Irwin” reflects neighboring settlement history, rather than an incorporated city government.
A Swedish colony, then two railway-era townsites
The county’s Hilmar Community Plan traces the colony to 1902, when Nels Hultberg promoted settlement by Swedish immigrants. The promise was irrigated farmland. Early community life centered around Tegner Road and what is now August Avenue; Turlock Irrigation District canals brought water in 1903.
Irwin developed along Lander Avenue in 1907 in anticipation of a railroad stop. The eventual railway townsite was Hilmar, where Tidewater Southern trains arrived in 1918. Hilmar became the southern end of a line reaching north to Stockton. Settlers gradually moved toward the new town center, and the Mission Covenant congregation relocated with them. The familiar Lander Avenue community grew out of that shift.
A church with a Swedish-language past
Hilmar Covenant Church, 20056 American Avenue, remains a tangible link to the original settlement. Its own history dates the congregation to 1902 and the current church building to 1919, with worship beginning there the following year. Services changed from Swedish to English in the mid-1930s. That language transition is a small, revealing piece of the community’s history: immigrant families were building institutions their children would inherit.
Twelve dairy families and a different use for milk
In 1984, twelve dairy families formed Hilmar Cheese Company to find a better market for their Jersey cows’ milk, which has a high solids content. The first production facility opened in 1985, and the visitor center followed in 1998. The company’s timeline shows how an agricultural enterprise expanded into cheese and dairy ingredients. Read our Hilmar Cheese history and visitor guide for the detailed story.
The Hilmar Cheese Company Visitor Center is at 9001 N. Lander Avenue. It brings exhibits, a café and a cheese shop together, making this the most straightforward first stop for visitors:
- Understand the process. The free self-guided exhibits explain dairying and cheesemaking, with viewing windows for the 640-pound cheese blocks. For a Saturday visit, the company asks visitors to call about access to the upstairs exhibits and windows.
- Make lunch part of the visit. The café lists grilled cheese sandwiches, soups including cheese chowder, salads and desserts. The shop sells Hilmar cheeses alongside other foods and gifts.
- Book an activity when that is the reason for going. Public ice-cream-making activities and the AgXscape dairy challenge have their own reservation schedules; they are separate from dropping in to explore the center.
Pizza on American Avenue
Pizza Plus is at 19935 American Avenue, Hilmar. Read our Pizza Plus guide for the Hilmar restaurant’s menu links, family history and mobile pizza trailer.
Azorean traditions and Yellowjacket history
Hilmar also has a strong Azorean cultural connection. The World Council of Houses of the Azores dates Casa dos Açores de Hilmar to 1977 and describes its cultural and immigrant-support mission. Its 2026 Holy Spirit festa program included folk dance, fado, processions and communal meals. That program is a record of the 2026 celebration, rather than next year’s dates.
Hilmar High School, 7807 Lander Avenue, offers another window into community identity. In its October 2, 2026 newsletter, the school reported a Hilmar Historical Society visit that brought former Yellowjackets’ photographs, memorabilia and artifacts to current students. For a public sports event, use the school’s schedules and ticket links.
A small library and a separate river outing
Hilmar Library, 20041 W. Falke Street, is a useful family stop. The county branch listing has its limited weekly opening days and Tiny Tales storytime. Use the county library system to find other branches and programs nearby.
Southwest of town, George J. Hatfield State Recreation Area, 4394 Kelley Road, offers a different setting on the Merced River: picnic areas, birdwatching, fishing and camping. It is a separate drive from the visitor center. The park was dedicated in 1953 on land donated by its namesake, a former lieutenant governor and state senator.
Access note: State Parks currently lists the Loop Trail as closed for repairs through 2027, or until work is complete. Check the park’s posted notices before making a trail walk your main plan. River swimming has no lifeguard service.
