Celebrate Trails Day is an annual spring celebration of America’s trails founded by the Rails to Trails Conservancy to encourage people to get outside and enjoy the nation’s exceptional trails and trail systems. Great opportunity to participate in the City Nature Challenge https://cncphilly.org/ to document biodiversity or iSeeChange https://scistarter.org/iseechange to help scientists understand changes near you (flooding, earlier blooming of flowers, weather changes, etc). Trails make getting outdoors and around by foot, bike and wheelchair more accessible for everyone. These essential outdoor spaces give us the space to swap car trips for bike trips, reducing emissions and helping the environment.
