Continue past the entrance to Villa San Michele, around a bend and to the right. Walkway paved and excellent views from top, although you can also walk down a bit, and even down to bottom of mountain if you have a few hours and are athletic. Steps are steep going down. We were there late in the day and only encountered a few people. Great picture taking!
