Before going: Reclamation's notice dated August 19, 2026 says the guided dam tour (listed at $40^* per person, sold at the site in person) is unavailable until further notice because of elevator repairs, while the power plant and self-guided tours run on their normal schedule, and tours may be cancelled without notice. Parking in the garage on the Nevada side is $10^* per vehicle, every vehicle is subject to inspection at the Nevada security checkpoint, firearms, explosives, fireworks and drones are prohibited, and America the Beautiful and other interagency passes are not accepted.
