Yellowwood State Forest is a great area for camping, hiking, fishing, kayaking, etc. It's just a couple minutes drive from the more popular Brown County State Park. I feel like this is still a bit of a hidden gem. Very easily missed, you will drive a few miles off the main road before you even get to the park, then you have a long stretch of gravel road with a several camping options (electric and non-electric sites available). There is a camp office where you can self register, and if you are there when the office is open, you can purchase firewood on site. Huge cart load for $5 or $6. Late fall, winter, and early spring when the nights are a little chilly, you may have the whole place to yourself, unlike Brown County State Park, where there will likely still be some campers scattered about.
