I've always been a fan of well-designed boardwalks in zoos, such as the one around the orangutan exhibits at Woodland Park; the huge boardwalk in Condor Ridge at San Diego Zoo Safari Park; the massive North American section of Sedgwick County Zoo; the South American pampas at Audubon Zoo; amongst many others.
Do the red panda(s) have full access to the large tree that has a branch over the visitor pathway? If so then that is a cool design idea.
