Take a break from the city’s frenetic energy with a visit to the Palermo Botanical Garden, just south of the port next to Villa Giulia Park. Established in 1786, the 10-hectare (25-acre) gardens contain plants from around the world: Southeast Asian palms, coffee and papaya trees, even cotton plants and sugarcane. A terraced pond blooms with lotus and water lilies, while the ruins of the 14th-century Church of Saint Dennis can be found amid the greenery.
