There is a lovely paved trail that runs the perimeter of Lake Elizabeth and offers views to Duck Island. The lake is surrounded by Central Park's many sports fields and green areas, which also have a great network of paved running trails to explore.

The perfect spot for a break! No shade here, but there is a bench, an informational panel, and a wooden observation deck. The views over the marshland here and the bay are pretty amazing.
