Tucked along the summit and eastern slopes of Sideling Hill about 10 miles west of Berkeley Springs, this 354-acre preserve is a quiet world of hardwood forests, natural springs, rocky trails and song birds. Protected by The Nature Conservancy and managed locally by the Potomac Valley Audubon Society, Eidolon offers a chance to experience the Eastern Panhandle at its most peaceful and wild.
The property was originally part of an 18th-century Fairfax land grant and later became the summer and weekend retreat of Louis and Marguerite Zapoleon. The couple named the property Eidolon, a Greek word associated with an image of the ideal. Marguerite Zapoleon spent decades documenting the plants and animals she encountered on the property. When she died, the property passed to The Nature Conservancy. In 2006, The Nature Conservancy and Potomac Valley Audubon Society established their partnership to care for Eidolon, with PVAS becoming the local steward of the preserve.
Eidolon contains more than four miles of trails and walking routes winding through its forested landscape.
The preserve’s highest point reaches approximately 1,600 feet, where openings in the forest provide sweeping views toward the surrounding mountains and Potomac River. The trails range from relatively gentle walking along the access road to moderate and strenuous sections that climb the mountain.
The Stone House at Eidolon Nature Preserve
Along the way, you may encounter:
- Mature oak and maple forests
- Natural, ground-fed springs
- Rocky hillsides
- Remnants of old quarries
- An old coach road from the 1700’s
- The remains of the Zapoleons’ stone cottage
Some of these features tell stories that stretch far beyond the preserve’s modern history. Stone from quarries on the property was used in the construction of the C&O Canal during the 1840s, while an old coach road dates to the late 18th century.
The preserve’s mature forests provide habitat for birds during both migration and breeding seasons. Spring brings a chance to search the forest for warblers, while the warmer months can reveal a remarkable variety of forest songbirds.
Among the species documented at Eidolon are:
- Cerulean Warbler
- Worm-eating Warbler
- Hooded Warbler
- Scarlet Tanager
- American Redstart
- Red-eyed Vireo
- Indigo Bunting
- Acadian Flycatcher
- Great Crested Flycatcher
- Eastern Wood-Pewee
- Yellow-billed Cuckoo
Cerulean Warblers are especially notable. PVAS reports breeding pairs along the gravel road leading from the entrance toward the cabin site and FAA tower during late spring and early summer. Worm-eating Warblers can be found along the slopes, while Hooded Warblers favor areas around the preserve’s springs and mountain laurel.
