Not really a secret, but surrounded by graves the sunlight feels brighter and the greenery sweeter! I swear! It’s close to prospect park but much less crowded (in terms of the living). There are so many species of trees that it qualifies as an arboretum, and they offer great early morning guided birding events! Must see: the pile of sticks left by visitors at the grave of Rex the dog, who hopefully gets to chew on them on the other side
