A run in the forest with just a wee bit of highway noise.

Need to Know

Bring a GPS with the route on it if it's your first time - just to be safe.


Bring stable shoes with good tread. The trail has lots of roots, rocks, puddles, slippery bits and puddles, especially after a rain. It's an easy trail with moderate grades and interesting curves / features.

The trail is well-marked most of the way with small circle tags on the trees with yellow, blue, green and red arrows for each of the four trails within the park. From about mile 1 to mile 1.5, there aren't many markers. This is the section of the trail that I suspect was revised in the last few years. Keep that in mind if you're using a paper map. This routing reflects the 2015 paper map iteration.

I suspect that a "local" would take you on a different route of the Landlocked Forest Loop, but what I've mapped is where the yellow markers are today. Aside from this one section with limited marking, the rest of the trail has markings in all the right places to keep you on the right track (so long as you're paying attention).

There is a pleasant creek/wetland that runs through the middle section, each crossing is on elevated boardwalks. A few other small streams have make-shift bridge structures to keep you out of the water. If there's been rain, expect some puddles and marshy bits, but I was able to make it through or around all without getting more than just a spot of water in my shoes.

Flora & Fauna

Trees, trees, trees - lots of them. Interesting rock outcroppings.

Plenty of wildlife to see. I saw birds, including a wild turkey, plus three deer.

The markers on this tree are typical for the trail.  All the markers are above eye level, so keep your head up so you dont' miss any.

This bridge is a little awkward - it's got a "vee" shape to it
