I had viewed this place from the freeway so often and had always wondered what it was and what is was being used for. I was pretty excited when I happened upon an opportunity to take a tour and find out. That was when they first started doing tours but from what I understand now, they are a bit harder to book. I just checked the website and they are indeed booked through June. All I can say is, it is worth the time so make an effort, you won't be disappointed!
The tour lasts approximately 2 hours and starts off with a little video. The video was pretty good and explained the history of the Castle and a bit of Phoenix History. You get to go into the castle and it is really pretty awesome. Like I said before, I always wondered what this place was and I had no idea of its significance to the area before. The people that work here are all volunteers, so help support and take a tour if you have the chance.
