Trail Day projects include new nature trail development, existing trail maintenance, erosion control, belay area improvements, and road maintenance projects.

We will work until 4:00 pm, and then celebrate our trail day accomplishments by thanking all volunteers with a cookout dinner, a raffle drawing, and a pull up contest. A free sack lunch and exclusive trail day T-shirt will also be provided.

This is your opportunity to help ensure the continued beauty and ease of access that Muir Valley is known for!
