I'll preface this with the fact that I am a Lexington, KY Native and have always lived close to the Kentucky Horse Park and Kentucky Horse Park Campground, but have never stayed there until this weekend.
We stayed on Loop A in site #38.
First, site #38 was a great large and fairly level site with 50AMP hookups and Water. There were no sewer hook ups, but the park has 2 dump stations that accommodate 2 RV/Trailers being dumped at one time. The site had a large amount of space between ourselves and our neighbors and we had a lot of extra space behind out paved site that was grassy. A great area for the kids/pets to run around.
The park has 2 playgrounds (one was closed due to COVID and the sanitizing that would have to be done. The park said they didn't have the staff to sanitize the playground further from the office/store). There is a community pool (it was closed because it isn't memorial day yet and the staff is still trying to determine if it will open this season after being closed all of 2020 due to COVID).
You're able to bring your Golf Cart if you would like but you must get a permit from the campground office/store. They say there is a rule that no one under the age of 16 or anyone without a valid drivers license is allowed to drive the golf carts, but this is clearly not enforced, as my kids were nearly run over (more than once) by young kids speeding around on the gold carts.
The park is great for bike riding and you can travel just a short distance to get to the Legacy Trail (a 12 mile paved trail great from biking/running that runs from the horse park into downtown Lexington). It rained most of the day on Saturday while we were there but in the evening, we got to get the bikes out and go see the horses as they were grazing in the fields.
Right next door, you have the World Famous Kentucky Horse Park. Their trail rides are back open (Ages 7 an older $25.00 per person) and they also have their Pony ride for kids 12 and under ($5 a person) opened back up. You can go visit the different barns, go to the museums, etc.
Just 1 exit north on I75 you have a Camping World, for all of your camping needs and then 1 exit after that you have a Walmart and Lowes for other things. Many food options as well.
There is a gas station just down Iron Works pike for all of your fuel and and snack needs. Attached to the gas station is also a liquor store.
Your smack in the middle of Georgetown and Lexington which both offer several family friendly Craft Beer Breweries/Taprooms, a lot of great local eating options and bars/nightlife options.
On Holidays now, at the Horse Park Campground, you have to have 5 day minimum stay, which can get a bit pricey.
All around though, great little campsite with easy access to I65/I64.
