Nature and Parks in Madrid

"Located right in front of the Prado Museum and next to the Retiro Park, this 20-acre botanical garden has been around for just under 300 years, as it was built for the royal family centuries ago. It showcased plants gathered from Spain’s colonies around the world. Today the garden contains multiple greenhouses to protect the many plant species ill-suited to Madrid’s dry climate and an “herbarium” with over a million species. Another fascinating exhibit is the garden’s bonsai collection, and you’ll find changing special exhibitions as well. The garden is always worth a visit, with the spring months perhaps the most picturesque of all. Entrance fees are €6 ($6.70)." - MATADOR_NETWORK
