Evan Barnard believes that all people should have access to nature. At age 14, he set out to create Whispering Woods, a Braille nature trail. The trail uses Braille signs and guide ropes. They help people who are blind or visually impaired explore nature without assistance. Visitors can enjoy a safe sensory experience by feeling the scratchy bark of a tree, hearing a bird’s song, or smelling the earthy odor of the woods. “It’s a transformative experience for many,” Barnard, now 21, says. —Rebecca Mordechai
