Come and discover Hall Ranch Open Space! Whether you have visited many times or this is your first, this program will reveal a Hall Ranch that you have never known. While taking a moderate 2-mile hike, we’ll tell stories, share fun facts, and explain the unique natural and cultural history of this open space property. You’ll use your powers of observation to interpret the natural environment at Hall Ranch.
Registration for most programs begins on the 20th of the month before the event.
Registration required.
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.
