Sharpen your plant identification skills, gain a deeper appreciation for our local ecology, and have a lot of fun along the way in this partnership with Friends of Olompali and the Marin Chapter of the California Native Plant Society outing!

Wear layered clothing, sturdy walking shoes, and bring snacks, plenty of water, and a wildflower guide if you have one.
