Spread across 127 acres, the Los Angeles County Arboretum and Botanic Garden is found in Arcadia, which is actually around 45 minutes outside of downtown and perfect for anyone wanting to get away the city bustle. The site is full of Native American and late 19th century history, as well as gorgeous flora, trees, ducks and peacocks. The Arboretum is like stepping into another world and is a must-see site for anyone interested in horticulture.
