Yep. Without having the tour i don't think it's possible
The below Dam Tour is offered at 9:30am; tours continue every half hour throughout the day until 3:30p.m.
You can visit the bottom part of the dam, but it just limited to the inside power plant part, not for outdoor
They sell tickets so u can go on tour and see how the dam works, then u get to go to the bottom.
How much is the tour?
Only if your with a tour
Yes but only with a tour guide. Security is expected to be very protective if your by yourself and not where they want you.
Only with a Tour Guide.
Inside tour currently closed due to lift probelm (March 2018)
