This Fallbrook venue is one of the few wedding facilities that we recommend outside of Temecula. And we have to include it because it is such a spectacular property.
Grand Tradition was built specifically for weddings. They aren't under the same strange rules that the county of Riverside imposes on Temecula venues. They just do weddings and they area really good at it.
There are two sites for ceremonies and two sites for receptions. You can't go wrong with any of your choices. However, if I was to recommend one, I'd go with the upper property; it has a tropical theme that I really enjoy.
Recommendation: change into some comfortable shoes after the ceremony. You'll walk a lot more than you will at other venues.
