Las Vegas, Nevada
Brilliant value for money! Really interesting, funny and informative! Our tour guide/stand up comic, was very funny and told us loads of fascinating facts about the dam, it's construction and the people who built it... I wanted to see the dam but didn't expect to enjoy the tour as much as I did as I was slightly fearful of being bombarded with too many boring facts, but it wasn't like that at all. It was an early(ish) start, but well worth it! There's not many people who can get me chuckling at 7.30am but our guide managed it straight away!
If you want to see the dam, I would definitely recommend this tour - it gives you plenty of time to wander round and take lots of photo's of the awesome scenery and the dam itself.
