My wife and I visited Kunana Dairy on our recent trip to Kauai September 2012. I found it on Tripadvisor highly recommended and the tour didn't dissappoint us.
When we arrived there was a plate of fresh baked cookies & banana bread and fresh ice cold lemonaid. Ryan, the owner, was friendly and knowledgeable, and encouraged questions about the operation.
The operation has fruit trees literally from all over the word, many I have never heard of. The Goats are obviously well looked after and are almost like pets, they love being petted.
At the end of the tour you have an opportunity to sample various goat cheeses - they were really good. You can also purchase goat cheese, chocolate bananas, fruits, honey, and various soaps & shampoos made from goats milk.
Give it a try if you're looking for something to do on Kauai that's a little different.
The only thing I would suggest to Ryan & Sarah is to supply bug spray to the guests.
-Bring some bug spray, the mosquitoes are pretty bad when you walk thru the grass.
