Register to participate in this winter trek led by Lower Merion Conservancy staff. Discover the mills, mansions, and farms that once existed in this 103-acre township park. In addition, guests can expect moderately steep trails that lead to an old ghost road to a creekside path beside towering stone ruins, then back up to the meadows and woods surrounding the Conservancy cottage.It is important to wear sturdy walking shoes. Be sure to meet in the public parking lot in Rolling Hill Park. On-leash, well-behaved dogs are welcome.
