They are Monday-Thursday 7:30am-5:30pm and Friday-Sunday 8am-3pm.

We hope you enjoy the OC Register article that highlighted the May 1, 2021 opening event.

The site will feature hands-on community educational programs on sustainable farming operations and will provide an opportunity for onsite STEM, biological science, horticultural and urban educational classes and community programs, farm-to-table dinners and special events. It will showcase Orange County’s development – from its agricultural roots to becoming the world’s 45th largest economy – and highlights the agricultural history of the United States.

The city of Aliso Viejo was incorporated on July 1, 2001. We celebrate their 20th anniversary.

Annual Events

Ranching and agriculture are central to the identity of the Moulton family to this day.

Maxwell, California

Moulton Roundup

In these times, family and friends are more important than ever. For over a century, the Moulton family has been gathering, working their cattle and building community just like they used to do on the Moulton Ranch during the ranching period of Orange County. At Moulton Museum we hope to tell the stories and share the traditions that bring us all together, connect us to our past and keep our community spirit alive into the future. Enjoy the video from our latest round-up held in Maxwell, CA in 2020.

Watch our 10 minute film about this historic event.

Pioneers of Orange County

Lewis Fenno Moulton & Nellie Gail Moulton

Lewis Fenno Moulton was a prestigious lawyer’s son. His father was a classmate and friend of President Lincoln. Lewis had worked at old Daniel Webster farm as an adolescent. As a part of Western expansion, many young men ventured West for opportunity. Lewis traveled to California at twenty years old by a boat around the Isthmus of Panama, train, and another boat to San Francisco before landing in soon to by Orange County. He learned to run a ranching operation by working at Rancho San Joaquin (Irvine Ranch) starting in 1874.

According to Louise Moulton Hanson, “In 1881 he bought Jonathan Bacon’s band of sheep and rented his 1,600 acres.” Lewis F. Moulton and Company was established with Jean Pierre Daguerre, a Basque sheepherder. The would developed a sheep and cattle enterprise along with agriculture.

On April 29, 1884 Lewis leased “17,000 acres, from Cyrus Rawson” (2018.43) which was a part of Rancho Niguel, a Mexican land grant once owned by Juan Avila. Throughout the years, Lewis purchased 21,723 acres which became known as the Moulton Ranch. 

Lewis and Nellie married in 1908. He built her a house on their homestead near the modern day Oakbrooke timeline near the 5 Freeway. They had two daughters, Charlotte and Louise.

Today, the land comprises much of Laguna Niguel, Laguna Woods, Laguna Hills, Laguna Beach, Dana Point, and Aliso Viejo. We aim to work with these cities to provide them with their heritage and preserve the past. Together we can educate the communities by exhibiting their history at the Moulton Museum.
