Decker Hollow is a locality in Northumberland, Ontario, Canada. It is classified as a village / hamlet. Decker Hollow is located at 44.0127°N, 78.4693°W.
Decker Hollow rests within the rising contours of Parson's Hill, where the land holds a stillness defined by its modest, sloping elevations. It lies 16.6 km east of Clarington, ON (from Clarington, ON: bearing 83°T), and is situated 14.3 km north-east of Newcastle Village. The soil here retains a cool, dense quality, supporting thickets of brush and hardwoods that catch the amber light of late afternoon, casting long, lean shadows across the uneven terrain. Air in Decker Hollow feels heavy with the scent of damp loam and pine, a persistent reminder of the quiet, sheltered nature of the hollow itself. Settlement in this corner of Northumberland grew from the necessity of clearing timber and working the stubborn, rocky earth. While the North Ganaraska River flows ten kilometres away, the local economy in Decker Hollow has long relied on small-scale agricultural efforts and the careful management of the surrounding woodlots. Life here follows the turning of the seasons, marked by the practical tasks of maintaining fences and preparing for the winter frost that settles early over the high ground. A sense of solitude persists in the landscape, providing a grounding influence for those who live among the slopes of Parson's Hill.
