Boulder Notable Tree Tour

This map highlights just a few of Boulder's special or 'notable' trees. A tree may be 'notable' if it is related to a famous or historical person, place, or event. A tree may also be notable if it is a unique species, contributes to the community, or is part of the Colorado Tree Coalition's Champion Tree Program making it among the largest of its species in Colorado. More trees will be added so come back to check out the map!
