Exciting and fun place to marvel at. The cost to park your car is excessive ($10) so just go past the garage and park for FREE at any of the designated areas. The tour costs $15 and we passed on that as well. Might be worth it to do once in a lifetime...So...the drive to the dam is slow and tedious. The security blockade border check is absolutely ridiculus. We actually saw a family of 4 standing by their car...hands up and on their heads. The security guys are on a power trip and they are condescending and rude. So just be prepared to show ID in case they ask...
