We did it just after Moro Rock. Kids were already getting tired as it was the end of the day. From the parking, this walk is not so short and goes down for a while. Take water and keep your energy for the return. You can really understand how big the trunk is thanks to a flat copy on the pavement. Once you reach Sherman, you can' t really realize it is the biggest of the forest as you have barriers keeping you away. But considering this is The GIANT, impossible to skip.
