We walked for about two hours to see this sign. (I was especially
impressed on how "amphitheater-like" was hyphenated:.)
You have to walk about two more hours to actually see what the
sign is talking about. It's a good idea to get a human Guide to set
the pace and to get the local vibe on things. Be forewarned tho',
time & distance go by differently here. 15 minutes can mean
2 hours, and "near" usually really means "far". It's also wise to
always bring a flashlight whatever time of day.
