The stone animals are the part people remember, more than the mound. Walk them. Do not climb on them.
Pair it with the mausoleum only if the reservations and the shuttle agree. Otherwise it is its own half day.
Getting there
Same mountain as the mausoleum. The walk between them is longer than it looks on a simplified map. Use the scenic shuttle if your ticket or the driver offers the stop. Do not miss the last shuttle down.
Staying nearby
City hotel. The cedar road is the point of being here, and then you leave. Lunch on the mountain is functional.
