A place to visit before you die, is the awesome Cornerstone Gardens in Sonoma, CA. In fact, there is a travel book titled: 1,000 Places to Go Before You Die, and Cornerstone Gardens is featured in it.
We visit quite often as it is a short and scenic 15-minute drive on Hwy 37 and then a quick turn down Hwy 121--about 5 minutes past Sonoma Raceway (formerly Infineon).
It's great for all ages, making it an excellent family outing--and is a perfect place to celebrate Father's Day, or any special occasion.
Admission to the gardens is free. You can stroll the beautiful and artistic gardens and let the kids roam, grab lunch or dessert at the new Park 121 Grill (serving blue bottle coffee), or enjoy some tastings at Keating or Meadow Croft Wines. Be sure to browse the art gallery and numerous shops that you'll want one of everything--so beware--or leave your wallet at home. :)
There is also a kids garden with sandpit--which we usually hit when we go--but it was super hot and feared a pre-nap meltdown was eminent, and decided to call it a day.
Please schedule some time to visit. You definitely will enjoy it. And bring your camera--you can't take a bad photo. If you have friends or relatives visiting, I highly recommend you take them--it will surely be a highlight of their trip.
Also don't forget your SPF, water, and other snacks, as you will probably end up staying for a while.
And remember to take a picture in the famous Big Blue Chair. You'll know it when you see it. :)
FYI: Cornerstone Garden is an annual host location for Tomatomania -- the world's largest (and most fun) heirloom tomato seedling sale. It came through last April, and is an event celebrating the tomato. You can buy and see over 300 heirloom tomato varieties, and you'll get to meet growers from all over the world. And if you ever have a question about tomatoes - they have a tomatopeadia on their site.
