You’ve likely heard of the term “old growth forest,” but what exactly does that mean? Well, it’s exactly what it sounds like. An old growth forest is an area where trees have been able to grow to a great age and have also been left relatively undisturbed. If you walk along one of these forests, you will see the same scenery inhabitants saw centuries ago. Located on Pine Mountain, Blanton Forest State Nature Preserve is the largest old growth forest in Kentucky and it is an amazing place to visit. There are hiking trails within the nature preserve that allow you to see the natural wonder of the area without disturbing it and the Knobby Rock Trail is definitely a favorite.

Blanton Forest is an old growth forest on Pine Mountain that is filled with history and jaw-dropping scenery. 2,200 acres of old growth are protected here, as well as thousands of acres that surround it as a buffer.

Within the preserve there is a trail system of 4.5 miles and about 3 of them make up the Knobby Rock Trail. Rated as moderate, this trail takes you through the towering trees, past rock formations, and to a view that shows off Kentucky's mountains.

The preserve opens at sunrise each day and closes at sunset. There is a parking area for visitors, as well as trail maps available. As with all hikes, be respectful of the land, especially in an area such as this.

As you hike along this loop trail, you'll eventually come to Knobby Rock, a sandstone rock outcrop. Be extremely careful while exploring the entire trail, but especially this area. It's not the best hike when this rock is wet or icy.

But when the conditions are right, you can enjoy this view from the rock. The gentle mountains seem to go on forever and you can only imagine what explorers and residents of this area must have thought of this view hundreds of years ago.
