Who We Are

Ascending the Giants is an Oregon based volunteer group of tree enthusiasts, climbers and researchers dedicated to documenting trees. Although our headquarters are in Portland, our team is international and our work, likewise, reaches every continent where forests exist. 

Our work consists of ongoing series of expeditions to measure the largest tree of each species. These trees demonstrate the pinnacle of what a species can be; they are called champion trees. We plan to showcase these specimens to increase knowledge of their existence and their ecological importance.

What We Do

Champion trees specifically are a focus, which we measure and welcome media professionals to share our findings. In tandem, Ascending the Giants is also known for assisting and offering access for canopy research, assisting film companies, climber training, professional presentations and adventure tree climbing.
