Lewis and Clark NHT Visitor Centers and Museums
Visitor Centers and Museums along the Lewis and Clark National Historic Trail
U.S. Army Corps of Engineers staff and volunteers provides tours of the powerhouse to see working turbines and generators of the hydroelectric dam. A viewing platform allows visitors to watch salmon and lamprey using the fish ladders, making their way upstream. Sea lions can even be found nearby, feeding on the vast quantities of fish. The area provides many other activities including Geocaches at the Bonneville Lock and Dam, the Bonneville Fish Hatchery, and the Bradford Island Recreation Area which offers a spectacular view of the Columbia River Gorge.
