There are also neighborhoods in Los Angeles called Elysian Park and Elysian Heights . Despite an urban location , Elysian Valley is near Griffith Park , Elysian Park , Eugene Debs Park , and Forest Lawn , as well as the Los Angeles River , and near to many neighborhoods heavily planted with trees , such as Silver Lake and Echo Park . The numerous `` greenbelts '' act to make the air much fresher in Elysian Valley than other urban enclaves , especially downtown .
