Knoxville – Ijams Nature Center. Only 3 miles from downtown Knoxville and it’s an easy 4. 8 miles. One of our favorite trails has finally reopened after being closed for several years due to extreme weather. Join our chapter and once again hike the River Board Walk trail. After this pre-holiday hike, we’ll celebrate our great year of hiking with a picnic in the park. Preregister with Rosie.
