I have made the trek to Kentucky many times to visit the different stud farms, inspect stallions, and photograph their horses, and just like anything else, you’ll find the farms that are more than happy to accommodate visitors, and those that are not so friendly.
As some others have already noted, some more commercial farms do ship their stallions in July to the southern hemisphere for their breeding seasons, so some may not even be on the continent for you to see. Also, November will be an extremely busy month for some farms with the Keeneland November Breeding Stock Sale taking place, the Breeder’s Cup events, and the World Equestrian Games ending in October, so it is suggested that you call a few months in advance to see if the farms can accommodate you - it helps to call the office and say something to the effect of: “Hello, my name is ___ and I’m going to be in the Lexington area on (dates) and would like to schedule an appointment to see (stallion).” By inquiring about their stallions, they are generally willing to help schedule appointments.
Also, DO call ahead to confirm your appointment, DO show up on time, and DO tip the grooms who are showing you the horses. I have tipped anywhere from $5-20 depending on the amount of time spent and horses shown.
Also, one thing I found EXTREMELY helpful in my first few trips was an EasyFinder map of Lexington - on one side it actually marked and labeled where all of the horse farms were.
Now, some of the farms I would recommend include:
It goes without saying that Claiborne Farm should be on your list of places to visit. The farm is rich in history, and the Hancock family has had an unprecedented effect in shaping the Thoroughbred horse into what it is today. They are extremely visitor friendly, and each tour includes a walk through the stallion barns (some of which, they will bring out for pictures) and concludes with a visit to the main cemetery located behind the office where horse racing greats Secretariat, Nijinsky, Round Table, Bold Ruler, Mr. Prospector, Swale, etc are buried. The Marchmont cemetery (where all of the more recent - last 20ish years interments are located, is not viewable to the public).
Three Chimneys Farm is very visitor friendly, and holds tours regularly. It is a beautiful farm, and the staff is usually very accommodating. Some of their stallions include KY Derby winners Smarty Jones and Big Brown and dual classic winner, Point Given.
Darley America (formerly Jonabell Farm) is one of the farms that shuttle stallions to Australia, but several of the older guys don’t, like champion Holy Bull, and Quiet American (sire of dual classic winner Real Quiet). It is a new (only a few years old), state-of-the-art facility. It is also the final resting place of Affirmed - Thoroughbred racing’s last Triple Crown winner.
Lanes End Farm has one of the most powerful stallion rosters of any farm in the world, incl: AP Indy, Curlin, Smart Strike, Kingmambo, Lemon Drop Kid, Mineshaft, Pleasantly Perfect, etc. Definitely worth a stop, Lanes End is owned by former British Ambassador Will Farish.
WinStar Farm has been one of my favorite stops, because I love their boys Tiznow and Distorted Humor - I was very disappointed when Victory Gallop got sold overseas as he was always good for entertainment.
Hopewell Farm wins the hospitality award from me. The people that work there are so genuinely nice. They stand champion Skip Away, as well as the white thoroughbred The White Fox, and is just across Pisgah Pike from Winstar.
Ashford Stud is absolutely breathtakingly beautiful - the Irish really know how to keep a horse farm. Unfortunately, they are another farm that shuttles their stallions south. However, leading sire Giant’s Causeway has not shuttled for several years now (insurance premiums were too high to risk it), and depending on the years some stallions are given a break and stay home.
Hill N’ Dale was once part of the old North Ridge Farm (sold and split years ago and now includes Hill N Dale, Vinery, and several other farms). Their stallion barn is very unique in it’s European design. Theatrical is also one of my favorites - he is pensioned now, but I can still remember the first time I met him a decade ago and he wouldn’t quit sticking his tongue out at the camera…HND is also the final resting place of the legendary Seattle Slew, who is buried a stone’s throw away from the stallion complex, complete with memorial statue. I attended his memorial service back in 2002, and Hill N Dale hosted a wonderful service befitting the late king.
Adena Springs is also a nice stop, and their stallions Giacomo, Awesome Again, Ghostzapper, and the recently retired Einstein are all worth visiting.
Another farm, which has yet to be mentioned in this thread, and that I highly recommend visiting, is Old Friends at Dream Chase Farm, which is located in Georgetown, KY - about 20-30 mins from Lexington and right off of I-64. Old Friends is a retirement farm, originally started for stallions, but now is home to mares and geldings as well, and their list of residents is incredible. Tours are offered on a regular schedule, and I should mention that it’s a fair amount of walking across the farm for those of you not used to trekking across fields. Farm founder Michael Blowen is one of the nicest people I have ever met, and listening to him tell stories about the horses on his farm (and the ones who have crossed the rainbow bridge) is fascinating. You will not be disappointed by visiting Old Friends. Their website is www.oldfriendsequine.org
That’s all I can think of right now, but if something else comes to mind I will make a note. Visiting KY’s horse farms is one of my favorite activities, and I’m planning to attend the BC events this year as well.
