There are bunches of places to hike in Northern Hillsborough. The Hillsborough River State Park has some great trails along the river at several different parks; Willderness Preserve, Trout Creek, Flatwoods and Violet Cury. Lettuce lake has a nice paved trail and boardwalks. Lake Park, if it reopens, has a nice trail. There are actually too many places to name. I suggest taking a look at the city website and the county website to get a better idea of your options. If you are only up for a short easy hike, try one of my favorites Eureka Springs.
