With a small pond, a creek, a wetland and a network of paths, picnics are a favorite family activity at this historic arboretum in Fairmount Park. The Display Gardens contain perennials, herbs, an accessible garden, everlastings, a demonstration garden and a vegetable garden. Take a stroll by the tranquil reflecting pool. Gaze upon Gambol I and II, two silver horses prancing in place along Belmont Avenue. Perennial Gardens, a butterfly garden and the Puryear Pavilion in the trees are other sites to explore.
