Andorra Natural Area sits in the northern reaches of Wissahickon Valley Park. It's a 210-acre nature preserve that features the Wissahickon Environmental Center and some genuinely wild terrain within Philadelphia's park system. You'll find extensive trail networks, environmental education programs, and a real sense of what this region looked like before European settlement.[1]
