Bluff (pop. 250) is located on the banks of the San Juan River, 26mi/42km south of Blanding at an elevation of 4,380 feet. Bluff was the first major settlement in San Juan County, though many of the original settlers moved north to Blanding and Monticello due to floods and drought. It is the third-largest town in the county.
The Victorian Kumen Jones House in Bluff was built in the late 1880's by one of the town's first settlers. It features excellent stone work. It is now privately owned.
The Nick Lovace House was built in the 1890's and was the home of Bluff's first stone mason. It is located at the northeast end of town and is surrounded by lilacs, cottonwoods and wild roses.
Sand Island is located 3mi/5km west of Bluff. This is the spot where many whitewater trips down the San Juan River begin. There are also hundreds of Native American petroglyphs in the area.
