This is a hobbit hole that is in Oregon Garden children’s garden. It is made out of a big drainage tube with round doors on either end and then landscaped over top. I can just imagine how much little kids would love this in their backyard. You could even use this soda bottle method of putting in a couple of these free solar powered lights so the kids would not be playing in the dark. This is an awesome diy project for a one of a kind play feature for your backyard. Croczine shared the picture and story about the hobbit hole.
