Tremper is a sprawling mountain at the south end of a range of low-elevation peaks between Warners Creek and Silver Hollow on the north, Stony Clove Creek on the west, Esopus Creek on the southwest and the Beaver Kill on the southeast. The latter three are closely paralleled by state highways 214, 28 and 212. Its summit dominates the view from westbound Route 28 at the small hamlet of Mount Tremper.
