I've passed this huge standing boulder many times. It was not until placing the cache that I discovered that several cars toot as they pass by.
If in a car, there is a space to pull off the road just north of the cache.
If heading up to find Talented Tapir from here you will go south 200m or so and take a dirt track off to the right through eucalyptus, then left and up through fields and rubber plantations.
