Herbarium Mediterraneum

Palermo's Herbarium Mediterraneum is a 30-acre botanical garden sitting right in the middle of the city, packed with tropical and Mediterranean plant species that thrive in the region's unique red soil. You get a fun, educational walkthrough that actually teaches you something rather than just letting you wander aimlessly — and it wraps up with a hands-on activity. It's the kind of place that surprises you with how much is crammed into an urban green space.
