for every hiker

MammothMarch cares deeply about our planet's future.


In addition to creating low- to zero-waste events, we want to give back to nature. That's why we're planting one tree for every registered hiker to support reforestation projects in the US!


Trees clean our air and water, create habitats for biodiversity, contribute to our health and wellbeing, and create jobs for social impact. 

When we first came across One Tree Planted, a 501(c)(3) nonprofit dedicated to global reforestation by planting trees to restore nature & biodiversity, we couldn't think of a better fit. They raise awareness about the importance of trees, offer businesses and events like ours a simple sustainability solution, and motivate younger generations to do something positive for the environment.

Help us make sure that each step taken is one closer to a healthier planet!
