About the Park

Loma Mar, Ca – San Mateo County Park

Science Spotlight: Banana Slugs

When the forest floor is damp at Sam McDonald County Park, it’s common to encounter large, yellow slugs. These slimy sights are banana slugs – one of the largest species of terrestrial mollusks.

Banana slugs can grow up to the incredible length of 10 inches, and live up to 7 years. They are found in forests along the West coast of North America from Alaska to California.

Although it’s tempting, if you find a banana slug along your journey, be sure not to pick it up! Contact with our skin can dry them out. Check out these cute critters with just your eyes, and watch your step for others as you continue on the trail.

Park History

Born the descendant of slaves in Louisiana, Sam McDonald settled down in Palo Alto, CA in 1903. While in California, he began what would become a long career with Stanford University as the superintendent of athletic grounds and buildings. He was well-loved by the Stanford community throughout his lifetime.

McDonald acquired the park and a small property on the grounds in 1917. After his death, he granted the land to Stanford, requesting that the park be used to enrich the lives of young people. San Mateo County acquired the land in 1958. It remains named in Sam’s honor, with a total of 867 acres of land.

Visit the Park

Please note that there is a parking fee. Dogs are not allowed.

Our love for trees brought us to the Heritage Grove Trail to Hiker’s Hut. However; regardless of the trail that you take or its length, you are guaranteed to get beautiful views of the Coastal Redwoods and the animal communities that live there.
