Short version: It was great! Lots of genuine historical items and information, and a big Bond-007 section too.
Long version: Didn't know what to expect, went in a on whim having walked passed it the previous day. Paid my money and was shown to an elevator. Up to the 3rd floor and there an intro sequence about being a spy, choose and memorize your legend, blah, blah, blah - bad 80s game show\video game stuff. Unimpressive first 15 minutes if you're older than 10.
After that things really improved, lots and lots of historical items including mini cameras, microphones, micro dots, gun lipsticks, gun umbras, disguising spy equipment, all accompanied by short by informative plaques explaining what you are looking.
Sections on the history of spying including World War II SOE equipment, Enigma machines, Bletchely Park, Cold war, Manhattan Project and Elizabethan spy masters.
Lots and lots of stuff (knifes, blades, and other movie props and the odd car) about 007 and the villains he meets\defeats - this section seemed to be a big hit with the teenage school party that appeared from nowhere.
Was expecting to kill an hour or so in the museum, 3 hours later I exited having rushed the last bits thinking the place was going close.
Well worth a visit.
Beautiful little place, was a good stop en-route to stretch the legs.
Read the website carefully about where to start the tour from - and the tours get booked up far, far in advance. Cannot prise the tour guide enough for an amazing tour. I know, when running, the project was supposed to be secret, but a little more advertising of the main reception would be most helpful.
I cannot believe somebody designed a road to just like a roller coaster - now if only they'd shut the road and let me take a rally car up and down it... Seriously it does provide some fanatically framed views of Mt Rushmore and the surrounding countryside.
If you take your own car into the valley, watch out the guided tour buses - they drive like madmen. If you do take your own car\hire car - keep the windows shut, I'm still finding red dust everywhere. There is lots and lots to photograph and view, but you'll never really be alone to enjoy the sights in the tranquillity they deserve.
Cannot be beaten for the price - FREE - just go to the visitor centre and ask for the free map - they are not on display - I assume they are hoping you'll buy an overpriced book.
The viewpoints\overlooks are well signposted, just drive between them and take in the natural beauty of the valley below you.
A bit commercialised, probably a bit over priced but still worth a visit. The scale of the crater doesn't really come home until you use the telescopes to locate the spaceman in the centre of the impact zone.
Absolutely beautiful. The Narrows walk\hike is amazing fun. You'll take hundreds of photos.
The park is great - park in Springdale town, then free shuttle buses pickup all along the main street taking you to the vistor centre and park entrance. Pay for your entry - KEEP THE TICKET WITH YOU. More free shuttle buses run around the park taking you to the major sights,
'The Narrows' hike is a must!
Recommended - I did the $30 Dam tour, well worth the money, the guides are knowledgeable and informative; their opening line was "if you have a camera - TAKE PICTURES" - you even get to photograph out the end of 1 of the 4 ventilation pipes that are half down the dam.
