Let’s welcome wildflower season at Caribou Ranch! We’ll walk up to three miles through this gem of an open space searching for wildflowers and the creatures that love them. Each participant will get a mini-field guide covering the plants currently in bloom. The guide also lists some butterflies, bees, and mammals that wildflowers attract. Along the way, we’ll highlight the fascinating relationships between plants and the living world around them. Registration for most programs begins on the 20th of the month before the event. Registration required. Register Registration is required through Discover Boulder County, Parks & Open Space’s volunteer and event registration system. If you’re new to the system, you'll need to create an account. But it’s easy and we only use your contact information to communicate about events you register for. We will never sell or give your information to a third party.
