Pros:
Everything about the whole operation here at Castoro Cellars Winery smacks of class and proper upbringing and money. The buildings, the tasting room, the clientele and the disc golf course all reek of class. The disc golf course, Whale Rocks, was certainly designed right. The wine and vineyard influence touches all points of the course. The course weaves in and out and sometimes over the vines. Wine barrels have been used creatively throughout whether they're used as outlines for the 30' putting circle or used as a base for a raised basket or stacked to provide a little safety for golfers waiting their turn to throw.
The equipment is excellent. The baskets are a very pretty powder coated blue color. The concrete tee pads are great. The signs are simple but give you what you need. There are brooms attached to the back of the benches on each hole. There are two raised baskets and one hanging one.
At each tee sign is a message below containing information on any topic such as the whale bones found here or about being good stewards of the land, the wildlife that call this their home, or respecting the workers while they are doing their work here. I didn't find these corny or preachy at all but actually quite inspiring. It actually made me want to be a good steward to both the land and the wine vineyards. And I actually don't care for the taste of wine.
The course is great fun but not terribly challenging, even for a old rec player like myself. Even after a terrible drive, I could almost always recover and save par. The course has an wonderful variety of holes types, uphills, downhill bombs, tunnel shots and Ace runs.
Security is tight. You have to trade your driver's license for a key to open the gate. You'll get your license back when your turn in their key. The cost to play is only $5 and you can purchase a yearly pass for $60.
Cons:
Did I find any cons? Yes, it's not a championship course. It's just north of being a rec course. Intermediates and advanced players would have their way here but I venture to say they would enjoy the hell out of themselves.
I don't think the $5 is going to discourage anyone. Playing the # 5 rated course in the state of California (January 2019) for $5 is a deal plus you get to taste some fine wine.
Other Thoughts:
Whale Rock DGC hosts a Cal Coast Series Championship so the course can be closed from time to time and also closes for rainy weather. Call and check for closures. There is a nice selection of t-shirts for sale in the tasting room (they got into my wallet for a couple). If you're driving up 101, you don't want to miss the opportunity to experience Whale Rocks Disc Golf Course and the wine tasting, too.
