There are tons of wineries all over the Temecula area! You can book a Winery Tasting Tour which typically includes 3 winery visits as well as multiple tastings at each stop, or feel free to just stop on by to one and enjoy your favorite wine!
Old Town Temecula is a great place to enjoy food, more wineries, old stores, and so much more! Definitely makes for a fun little adventure day!
Pechenga Resort and Casino is always a great option if you're looking to have some fun gambling and enjoy plenty of drinks! Mine as well make it into a vacation while you're out here
