Multnomah Falls is awaterfall located onMultnomah Creek in theColumbia River Gorge, east ofTroutdale, betweenCorbett andDodson,Oregon, United States. The waterfall is accessible from theHistoric Columbia River Highway andInterstate 84. Spanning two tiers onbasalt cliffs, it is the tallest waterfall in the state of Oregon at 620 ft (189 m) in height.[1] The Multnomah Creek Bridge, built in 1914, crosses below the falls, and is listed on theNational Register of Historic Places.
The land surrounding the falls was developed bySimon Benson in the early-twentieth century, with a pathway, viewing bridge, and adjacent lodge being constructed in 1925. The Multnomah Falls Lodge and the surrounding footpaths at the falls were added to theNational Register of Historic Places in 1981. Contemporarily, the state of Oregon maintains a switchback trail that ascends to atalus slope 100 feet (30 m) above the falls, and descends to anobservation deck that overlooks the falls' edge. The falls attract over two million visitors each year,[2] making it the most-visited natural recreation site in the U.S.Pacific Northwest.[3]
The falls drops in two major steps, split into an upper falls of 542 feet (165 m) and a lower falls of 69 feet (21 m), with a gradual 9 foot (3 m) drop in elevation between the two, so the total height of the waterfall is conventionally given as 620 feet (189 m). The two drops are due to a zone of more easily erodedbasalt at the base of the upper falls.[4]
Multnomah Falls is the tallest waterfall in the state ofOregon.[1] It is credited by a sign at the site of the falls, and by the United States Forest Service, as the second tallest year-round waterfall in the United States.[5] However, there has been some skepticism surrounding this distinction, as Multnomah Falls is listed as the 156th tallest waterfall in the United States by the World Waterfall Database (this site does not distinguish between seasonal and year-round waterfalls).[6][7] The World Waterfall Database disputes claims that Multnomah Falls is the fourth-tallest waterfall in the United States, which has been claimed in such sources as theEncyclopedia of World Geography (2013).[8]
Underground springs fromLarch Mountain are the year-round source of water for the waterfall, augmented by spring runoff from the mountain's snowpack and rainwater during the other seasons. This spring is the source of Multnomah Creek.[9]
Multnomah Creek drains intoBenson Lake approximately 1,300 feet west of the bottom of the falls.
The waterfall formed around 15,000 years ago[2] at the end of ahanging valley, and was created by theMissoula floods.[10][11] According to the creation story from theMultnomah tribe (from whom the falls take their name), the waterfall was formed after a young woman sacrificed herself to theGreat Spirit to save a Multnomah village from aplague by jumping from the cliff, and the Multnomah peoples were saved.[12] After her death, water began to flow from above the cliff, creating the waterfall.[12]
The falls were noted in the journals of explorersWilliam Clark andMeriwether Lewis during theirexpedition through the Columbia River Gorge in 1805.[13] In an October 30 journal entry, Lewis notes:
... passed Several places where the rocks projected into the river & have the appearance of having separated from the mountains and fallen into the river, small niches are formed in the banks below those projecting rocks which is common in this part of the river, Saw 4 Cascades caused by Small Streams falling from the mountains on the Lard.[14]
The origin of the falls' naming is unclear; scholar Lewis A. McArthur, inOregon Geographic Names, suggested that S. G. Reed, a prominent mercantile clerk in Portland and native ofMassachusetts, may have been the first to apply the name with the idea of popularizing sites along the Columbia River for steamboat excursions.[15]

Beginning in 1884, theOregon Railway and Navigation Company operated a stop at Multnomah Falls on their railway, which spanned from Portland toPasco, Washington; this stop continued to operate untilWorld War II,[18] and included a timberbowstring truss bridge that spanned the falls at the present bridge's location.[15] Around 1891, the bridge was reinforced, but was dismantled in 1899.[15]
On January 28, 1915,Samuel C. Lancaster recommended to the Progressive Business Men's Club of Portland that a trail be built from the base of Multnomah Falls extending to the top ofLarch Mountain.[15] The Club raised several hundred dollars to finance the trail, and Portland financierSimon Benson and his son Amos S. Benson pledged an additional $3,000.[15] TheUnited States Forest Service appropriated a total of $1,500 and agreed to survey and build the trail in addition to the lookout on Larch Mountain. Benson financed Italian stonemasons to construct a bridge at the falls to allow visitor access.[19] This bridge, named the Benson Footbridge, spans the lower falls at a height of 105 feet (32 m), and provides an expansive view of the upper falls.[15]
On Labor Day 1915, Benson donated over 1,400 acres (570 ha) of land which included most of the falls as well as nearbyWahkeena Falls, to the city of Portland.[15] The Oregon Railroad and Navigation Company subsequently donated the land at the base of Multnomah Falls contingent upon their agreement that alodge would be constructed at the site the same year.[20]
Late that year, architectA. E. Doyle, who designed Portland'sMeier & Frank Building, was commissioned by the city to design the Multnomah Falls Lodge, which was completed in 1925.[17] The lodge, built in a "Cascadian" architectural style using native split fieldstone laid irregularly. The building features a steeply pitchedcedar-shingled gable roof withdormers and large chimneys.[15] In the early through the mid-twentieth century, the lodge provided both meals and lodging to travelers.[20] Contemporarily, it provides meals, a gift shop, and an interpretive center.[20] The lodge and footpaths were added to theNational Register of Historic Places in 1981.[17]

In contrast to other falls along the Gorge, the Multnomah Falls area is accessible viaInterstate 84 east ofTroutdale, Oregon, and is a "designated scenic area" by the state of Oregon.[3] The falls are the most-visited natural recreation area in thePacific Northwest, with over two million annual visitors.[3] The rest area and tunnel under the road (as well as theUnion Pacific Railroad tracks) allow Interstate travelers from either direction to stop and visit the falls.Columbia Area Transit operates theColumbia Gorge Express to Portland and Hood River.
During the summer season and holidays the parking lot along the freeway access can fill up very quickly which prompts a gate to come down and a reader board sign along the freeway before the offramp flashes that the parking lot is full.
Several tour providers offer a variety of ways to access Multnomah Falls from ebike rentals to waterfall shuttles that stop at all of the waterfalls near Multnomah Falls
A paved foot trail[21] leads to Benson Footbridge, a 45-foot (14 m)-longfootbridge that allows visitors to cross 105 feet (32 m) above the lowercascade. After a viewpoint of the upper falls, the trail continues to ascend to an elevation of 785 feet (239 m);[21] it consists of eleven switchbacks which reach a forested talus slope 100 feet (30 m) above the falls.[22] The trail then descends to anobservation deck (elevation 660 feet (200 m)[21]) overlooking the falls' edge,[22] providing visitors a bird's-eye view of the Columbia Gorge and also of "Little Multnomah", a small cascade slightly upstream from the "upper" falls, which is not visible from ground level.
There are a number of trail junctions along the footpaths ascending to the falls' observation deck, which allow access to a 5.4 miles (8.7 km)[23] trail loop to other nearby waterfalls.[24] TheMark O. Hatfield Memorial Trail, one of several, starts at the falls and continues through the Oregon side of the Columbia River Gorge toStarvation Creek.[25]
In 1991, a wildfire damaged over 1,600 acres (650 ha) near the falls, and resulted in the closing of Perdition Trail, a hiking trail that branched off the main trail to the falls' observation deck.[21] The trail is permanently closed and deemed unsafe for passage.[21]
OnLabor Day in September 1995, a 400-ton boulder, loosened byweathering anderosion, fell 225 feet (69 m) from the face of the waterfall into the upper cascade pool, above Benson Footbridge. It caused a 70-foot (21 m) splash of water and gravel to wash over the footbridge, causing minor injuries to twenty members of a wedding party that happened to be on the bridge posing for photos at the time.[26]
On January 9, 2014, a falling rock damaged a portion of the bridge walkway and concrete railing, leading the Forest Service to close the bridge until repairs were completed.[27]
In September 2017, the lodge was threatened by theEagle Creek Fire in the Columbia River Gorge, which resulted in the lodge and fall access being closed to the public. The lodge reopened on November 29, 2017, though the U.S. Forest Service announced that footpath access to the waterfall would remain closed until an indeterminate date due to concerns overlandslides.[28] The trail to the Benson Bridge reopened in June 2018,[29] while the remaining trails along upper Multnomah Creek and to Wahkeena Falls, the top ofLarch Mountain,Devil's Rest, andAngel's Rest were repaired and reopened in November 2018.[30]
A five-ribbedspandrel bridge, the Multnomah Creek Bridge, was built in 1914 to bring what is now theHistoric Columbia River Highway across Multnomah Creek below the falls. It is 67 feet (20 m) long and is acontributing structure in the highway's listing on theNational Register of Historic Places, and in its designation as aNational Historic Landmark.[31]
