The Marin Art and Garden Center is a local Marin Favorite.
I have been here numerous times both with the family and for school field trips. The kids enjoy themselves. The last trip with my sons class the crew of Master Gardeners had four stations set up; 1. Pond ecosystem where the kids got nets and pulled in samples of aquatic life to study. 2. Compost pile that provided more material for scientific study :-). 3. Bee, hummingbirds and other birds-samples of nests and wood pecker granaries. 4. Skeletons of different animals. Great time.
The Rose garden was hit with the kids, both visually and aromatically. The sun garden was in full bloom.
