You will have a blast. Everything there is 2 way trail except for Hobbs Hollow Flow trail which is downhill only. Brown County State Park is known for Fun, Fast and Flow and you can apply that to basically every trail there. My personal favorites are Walnut, Hesitation Point, Green Valley and Hobbs Hollow. But it really depends on what I’m in the mood for that day. Schooner is super technical, to the point of ridiculousness in places, but you can also hike a bike any section that you don’t like. Walnut is about as technical as I like before it’s not really fun anymore, but that’s all personal preference. There are some that would say Schooner is the most fun, if that’s your thing. Ultimately I would recommend you ride every trail there over the 4 days, they’re all so good.
The maps you’ll find are accurate and it’s pretty easy to figure out once you’re out on the trails. There’s good signage. They will give you a property map that is accurate at the gate when you go in. I would suggest keeping this with you at least as a backup to mtb project on your rides. You’ll need to purchase and Off Road Cycling Permit at the gate.
Limekiln is the only one that has a trail head at the campground, so you’ll probably start on that and return on that every ride. It’s one of my favorites too and is super fun. Pro tip: If you have two vehicles, or someone that can pick you up, I often start my rides in the campground and then end at the north parking lot by the outdoor pool. You can do multiple loops and ride all the trails that direction and not have to eventually climb back up to the campground. I do this a lot when I’m there camping several days with family and want to keep my legs a little fresher.
In 4 days you can try everything in the park multiple times and in multiple directions to determine your favorite. You can also go south out of the campground and ride newer trails in the state forest but I don’t have experience on those. The stuff in the park is so good that I never leave the park.
Make sure to check out the little town of Nashville while you’re there. A stop at Big Wood’s Restaurant/Brewery or Big Woods Pizza is a must for any trip to Brown County.
