If one has memorized the 27-syllable mantra of Fudo Myo-O, which is transmitted during an initial 3-day visit to the monastery, then he may participate in walking meditation during subsequent visits. He may practice either as a householder bodhisattva in Shugendo or as a monk bodhisattva in Tendai. The type of walking meditation known as kaihogyo starts with repeated 5-hour circumambulations of Cobb Mtn under the guidance of one of the resident monks.
It's stop-you-in-your-tracks beautiful there.
