If you need a quiet break from the hustle and bustle of Los Angeles, you can head to the Exposition Park Rose Garden. From mid-March to December every year, you can enjoy about 20,000 roses, nearly 200 different rose varieties. You can also use the Rose Garden as a family outing destination, since it's located near the California Science Center. The Rose Garden is open from 9am until sunset. You can choose to travel on weekdays with fewer activities.
