Tivoli Park, Ljubljana
Concierge.com's insider take:
Formerly the recreational grounds of Tivolski Grad—a 17th-century stately home that is now the International Center of Graphic Arts—Tivoli Park has a zoo as well as acres of formal landscaping, bisected by a grand Plečnik promenade. Better still, there are paths that climb the densely wooded hills protecting the western edge of the city, and the air is fragrant with pine. It may only be 15 minutes' walk from the center of this capital city, but it feels a world away.
