Dunderberg Mountain stands at the so-called southern gate of the Hudson Highlands where the region's namesake Hudson River enters a dramatic gorge. It rises about 1,086 feet (331 m) from the river's west bank above Jones Point, New York, within Bear Mountain State Park and the town of Stony Point in Rockland County, New York.

Dunderberg (also historically Donderberg) is a Dutch word, meaning "thunder mountain," so called by the early Dutch settlers because of the frequent thunderstorms in the vicinity.

The bulk of Dunderberg projects into the Hudson River, which describes an arc about its eastern side. Tidal marshes of the river, Snake Hole Creek and Iona Island, lie to the north. On the northwestern side is the abandoned hamlet of Doodletown. At Dunderberg's immediate southern slope is the Hudson River, while to the southwest are outlying neighborhoods of Tomkins Cove, a community or segment of Stony Point.

The mountain as labeled on current U.S. Geological Survey maps and a widely used hiking map, extends about a mile and a half from its easternmost footing on the river at Jones Point. But several summits lying still farther to the west and southwest are evidently part of the Dunderberg formation, or massif, as described by at least some editions of an influential area hiking guidebook. These include Bald Mountain or Bockberg (1,130 feet (344 m)), as well as the Timp (984 feet (300m)), each of which are, however, separately named by the USGS. The Boulderberg, labeled as such on certain maps of historical interest, lies a short distance to the south of the Timp.

As Dunderberg's crest runs inland latitudinally from the river, Timp Brook splits it into northerly and southerly ridges; Bald Mountain lies at the end of the northerly ridge, while the Timp terminates the southerly ridge about two-and a half miles southwest of Jones Point. Timp Brook emerges from a small swamp between the two ridges to flow down steeply to the north around Bald Mountain and thence to the northeast, into the valley known as Doodletown Clove between West Mountain and Dunderberg.

Closely following the upper course of Timp Brook was once the main route into Doodletown from the southwest. A half-mile farther west, an old farm road, later used as a fire road and now a foot-path, also enters Doodletown valley, through a narrow gap known as Timp Pass between the Timp and West Mountain. However, since the late 19th century, the main road up the Hudson (now 9W) has circled around the base of Dunderberg near the river.
