The Cuyahoga Valley National Park is offering the Cuyahoga Challenge, a program to encourage hikers to visit 10 designated trails.

Participants who register and visit all 10 trails will earn a commemorative patch designed by local artist Chuck Ayers.

The trails range from easy walks to challenging hills and hikers can walk by themselves or join a ranger-led program.

To qualify for the patch, the trails must be hiked between Sunday, June 1 and Tuesday, Sept. 30.

Entry forms are available at any park visitor center or can be downloaded here.
