The arboretum surrounds Curtis Hall, once the ballroom of the family mansion, which now is operated by the Cheltenham Township Parks and Recreation Department. It features hills, two ponds, and over fifty types of trees.
For more than twenty-five years, nearby Cheltenham High School has used the grounds of Curtis Arboretum as its home cross-country course during the fall racing season. The course measures approximately 2.9 miles (4.7 km).
