Visited this jewel in the desert for the first time last night while attending the Grapes and Hops Festival.
The festival itself was great. (I'll save details of that for their own review). And the setting of the Springs Preserve was a wonderful choice. I arrived there around 7, so it was already dark, so I wasn't able to enjoy the scenery as much as I probably would have during the day.
I have horrible allergies (basically every plant/pollen/vegetation native to Vegas) and this took a toll on me. Despite that unfortunate detail, this place is definitely worth coming back to visit again.
I can see why this is a popular location for weddings, high school reunions, and any other special events. I've been told the museum is great and this place even has a Wolfgang puck cafe/restaurant!
The Springs Preserve is a great way to "get out of the city". It really makes you forget you're in a metropolis.
