After biking day before, we hiked all we had not seen. From main visitor center to South Kaibab and back. Then to Bright Angel and bus back with a prickly pear beverages on the way. Less crowded and best views while on the trail was heading east from Mathers Point to South Kaibab Trail. I turned around 1/8 mile down and Anne went down another 1/4 mile. Doable but no fun for me.
