Black bears are busy gorging on berries and other food in preparation for their long winter sleep. Join volunteer naturalists on a moderate 3-mile hike to learn about the life cycle of the black bear and how people and bears can share our wild places. 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.
