When visitors enter, there's so much to do: Go out on the balcony, enjoy the view,
Or learn about nature, or purchase a snack,
Or birdwatch in Central Park with a field pack.

The view is a must—it inspired the name:
A "beautiful view" is the castle's main aim.
Look down to see turtles who swim with wide strokes
Through silence that's broken by frogs' mighty croaks.
