The W.A.C. Bennett Dam stands as one of the world's largest earth-fill structures at 183 meters tall and 2 kilometers wide, impounding the massive Williston Reservoir visible from space. This 1960s engineering feat powers nearly a quarter of British Columbia's electricity through the underground G.M. Shrum Generating Station. Dam engineering tours deliver rare access to turbines, penstocks, and control rooms, unmatched in scale and raw power.
Start at the Visitor Centre with interactive exhibits on hydroelectricity, then board guided bus tours into the powerhouse for turbine views and tunnel walks. Explore the First Nations Gallery and exterior platforms overlooking the dam face and reservoir. Audio tours and films enhance the technical deep dive into water-to-energy conversion.
Target May through September for open season and mild summer weather; expect 10-25°C days with possible rain. Roads are paved but remote, so drive a reliable vehicle with full fuel. Prepare for security checks and no large bags inside.
Tours operate on Treaty 8 First Nations territory, with the "Our Story, Our Voice" gallery sharing Indigenous views on the dam's construction and impacts. Local Hudson's Hope community benefits from 12,500 annual visitors, boosting nearby campsites and businesses. Power Pioneers offer free entry perks for members.
Plan visits from May 17 to September 1, 2025, when the Visitor Centre opens 10 a.m. to 5 p.m. daily; arrive early for guided tours as they fill up. Book audio tours or season passes online via bchydro.com/bennett or call 250-783-5048; admission starts at CAD 8 for adults including taxes. Confirm operations as hours can change without notice.
Wear layers for cool underground tours and bring binoculars for reservoir wildlife spotting. Rent hard hats provided on-site but pack comfortable walking shoes for exhibits and platforms. Download the BC Hydro app for extra engineering facts beforehand.
