Slade Brook

Lower Slade Brook falls

The 38-acre Jim and Evalyn Hornig Natural Area at Lower Slade Brook offers a quiet retreat with easy walking terrain next to Slade Brook.   From Hanover Center to its confluence with the Connecticut River, Slade Brook’s banks are undeveloped and graced by convenient hiking trails through varied forestland.  The Conservancy’s protection of this property ensures that Lower Slade Brook will always be a pristine environment for people to enjoy and where the native flora and fauna can flourish. The Upper Valley Land Trust holds a conservation easement on the Hanover Conservancy’s property here, and the Conservancy holds easements on the abutting sections of nearby landowners’ properties.


A Conservation Development Success Story

When a developer presented a plan for 17 houses in this area, the Conservancy (then known as the Hanover Conservation Council) proposed an alternative that resulted in 10 homes clustered on 20 acres on the south side of the brook, on the site of a former gravel pit, and the rest of the property left intact. This solution protected the brook and its undisturbed valley, while providing recreational trails for homeowners in the Purling Brooks neighborhood and the wider community.  Jim Hornig, former president of the Council, was the inspiring force behind the creation of this preserve in 2005, and the Council gratefully named the Natural Area in honor of Jim and his wife, Evalyn.

Trail Information

The main foot path through the Natural Area is the 0.5 mile Waterfall Trail on the north side of Slade Brook. The trail leaves the small trailhead parking area off River Road and follows an old woods road before climbing through the brook’s little valley, offering beautiful views of the falling waters, which are spectacular during high water.  Beyond the last of the three falls, the trail heads away from the brook and up to a plateau. After a right turn just beyond the boundary, the 0.25 mile Lyme Road Connector Trail brings you to Route 10.

A short (0.15 mile) side trail just above the third falls (no bridge) leads to the Purling Brooks neighborhood. The public is welcome to use this trail as far as the Natural Area boundary, but may not continue across private land. Connections to other trails in the area are not currently maintained.
