In terms of physical geography, nearly all of Hardyston (excluding the portion of the Township west of Hamburg along Route 94) lies within the New York-New Jersey Highlands, part of the greater Crystalline Appalachians that extend as far south as the Blue Ridge Mountains. Hardyston is home to portions of Hamburg Mountain (east of Franklin) and Pochuck Mountain (near Scenic Lakes) within this region. The remaining northwestern portion of the township lies within the Ridge-and-valley Appalachians. The prominent feature in the ridge-and-valley portion of the Township is the Wallkill Valley, through which the Wallkill River flows northeast to New York state.
Hardyston was incorporated by an Act of the New Jersey Legislature as one of New Jersey's original 104 townships on February 21, 1798. Over the centuries, portions of the township were taken to form Vernon Township (April 8, 1793), Sparta Township (April 14, 1845), Franklin (March 18, 1913) and Hamburg (March 19, 1920).

Postal ZIP codes covering Hardyston Township are 07460 Stockholm, 07416 Franklin Borough, 07419 Hamburg Borough, and a small part 07848 Lafayette Township.
Hardyston was serviced first by the New Jersey Midland Railway, which built the station in Stockholm. However, there was a dispute over the name as that area was known as Snufftown because of the snuff factory along the Pequannock River, which provide the water power. Through a series of events between the residents of Stockholm and the railroad, the area eventually changed the name from Snufftown to Stockholm. Later, it was the New York, Susquehanna and Western Railway, who provided service into the early 1960s when a mud slide removed a large section of trackage in West Milford Township and coupled with low productivity, the line was not repaired and service was disconnected. Today, the New York Susquehanna and Western Railway runs freight through Hardyston. The main highways are Route 23 and Route 94. A large eastern portion of the township is part of the Pequannock Watershed, which is owned by the City of Newark in Essex County for their water supply.
