Your Safety

For your safety we ask that you remain on established trails while visiting the Park. Poison oak and stinging nettles are common. By staying on the trails you will not only prevent your exposure to poison oak and stinging nettles but you also help us preserve an old growth forest ecosystem in which these coast redwood trees need to survive.

Did You Know?
Every year Convergent Ladybugs migrate to Muir Woods from California’s central valley seeking the cool refuge of the redwood forest. You can see them resting in large clumps on plants and fence posts.
