If asked, I don't think that our girls would be able to pick a favorite activity from their afternoon spent exploring the new Learning Campus, but I can tell you this... there isn't an area that they didn't enjoy, but they did have to be pulled away from The Nature Play Garden at the end of the day.
The "boulder bubbler" feature of the park's recirculating runnel got some attention, as did the natural climbing space created from tree trunks and stumps. When placed in such an area - one devoid of man-made playground equipment and cut-off from tech, it's fascinating to see the natural curiosity take over as the kids seek to explore.
