Yes, you can dig. It's great for the kids. Like the previous poster, we had to almost drag our granddaughter away from there. I would suggest that you make this your last thing you do in the Boneyard. The adults can sit on the rocks to the side and rest after running through the "playground" part. We also made this the last thing we did for the entire day. We could use the excuse "but honey, the park is going to close and we don't want to be here all night!". OK, she was five at the time so she fell for it.
