Went to Lake Mead NRA after see The Hoover Dam. It cost $5 to drive in & look around. We didn't have a lot of time there, but would still recommend it if in the area.
We went to the boat launch area and walked a little bit. Lots of ducks, fish, geese there. Crazy carp were eating popcorn that people bought from the boat shop - craziness.
There's lots of hiking to do there. We just didn't have enough time. Would have liked to hike the White Rock Canyon & Arizona Hot Springs.
We'll go back to one day do the Lake Mead Cruise on the Desert Princess. It's closed in Dec for renovations. Sightseeing cruises Feb thru Nov.
