There are a ton of hiking in the area. Lake Fayetteville has kayaking, hiking and biking trails. It's actually a really cool area.
There is a top golf in Rogers area. It's honestly a cool area for a lot of outdoor nature stuff. Crystal Bridges is cool, it's an art museum with some cool trails to hike around.
I love Fayetteville. Campus is awesome as well, you can go up to Old Main, it's a cool building.
