Our favorite park in Lexington is Jacobson. It's pretty big and has an amazing playground, water park, basketball courts, pond for fishing, a dog park, and much much more. We love to go on walks here. It's definitely a great place to go for some outdoor family fun!
The Pinnacles are our absolute favorite place to hike. If you don't mind to travel 45 minutes down the road to Berea, KY for an amazing day of hiking, we strongly recommend. There are multiple trails from easy to hard, all with beautiful lookouts once you get to the top. It's definitely worth the trip.
