While we had planned to visit the Hoover Dam, our stop at the Glen Canyon Dam was more accidental. Although it is a river dam with a huge hydroelectrical power station, just like Hoover Dam, and has formed the second largest artificial lake in the USA, it is less impressive, at least to me. But since the visitor center was just beside Highway 89, and we were planning to go to Page for Horseshoe Bend anyway (on our way to the Monument Valley), we stopped right there.
In contrast to Hoover Dam, you cannot cross the dam by foot without a guided tour, let alone drive on it; instead the visitor center offers a stunning view from a large glass rotunda overlooking the dam and the nearby bridge. If you walk around the visitor center, you can spot a few details more closely.
The Carl Hayden visitor center is laid out quite well and offers many interesting historical details as well as a relief map of the canyon area and lake. Guided tours across the dam are available for 5$, the usual security stuff applies.
While we toured the visitor center, several people used the small lawn in front to have a lunch break in the shadow of a few big trees.
For another view of the dam you can enter the nearby bridge, which is secured with wire-mesh fencing on both sides, but there are circular holes for photographers. Since there is heavy traffic, the bridge keeps vibrating, so prepare for short exposure times if you want to take pictures there.
This little guy was not impressed and took a sunbath on the balustrade instead.
If you are more keen on larger alien critters, there is a nice display of a pterosaur outside the visitor center, unfortunately behind a fence.
More interesting than the dam, the lake (which is one of the most popular recreational areas of the US) or the bridge are photos from the era before the dam – a beautiful collection can be found here, with a map highlighting specific areas.
Not a must-do stop, but due to its convenient location a good place for a break anyway.
