I've been here a few times. It is a good place to bring out of town visitors, young or old. The guided tours are educational and good way to learn about Oregon wildlife. You get pretty close to the animals who, it is obvious, are well cared for with clean pens and fresh water. Also obvious if the affection of the guides and others on staff for the animals.
For the tour, you need to be able to walk on slightly hilly, uneven terrain - may be a problem for less secure walkers. I think they have a cart now. The total walking distance is not that far. The tour takes maybe an hour, hour and half. Be sure to visit the gift shop.
