A tour of the facility shows you how these award-wining wines are made and bottled. You’ll also want to take a tour of Crystal Cave while you’re here.

Sophia M/Trip Advisor Why exactly is there a natural wonder attached to a winery, you ask? Well, it all started in 1897 when workers discovered Crystal Cave while digging a well for the winery.

Crystal Cave is 35 feet below the surface and is about 12,000-15,000 years old. It’s a truly unique natural wonder that you have to see to believe.

Carl S/Trip Advisor Today, you can tour the cave for $8 per person and $4 per child every day from early May until late September, according to the winery’s website.

What’s so special about this beautiful cave is the fact that it’s the world’s largest celestite geode.

Outside, you can enjoy your wine in the wine garden. It’s the perfect way to sit back and truly take in the experience.
