Welcome to the #10Trail Challenge registration page. We are so excited to bring back the Challenge for another year. Remember you have the whole month of July to hike as many featured trails you can. Along the way, don't forget to snap selfies at the selfie stations, capture your favorite views of each trail, and share your experiences with us! If your social media is set to private, send your post as a message to help us track your trails. Please keep registrations to 1 per household.
