The trail itself is great for hiking and running. I try to hike the premier trail 2 times a week. If you start from the parking area by Shelter 1 and enter the trail at shelter 2 you will have 2 very significant inclines. At the 2.5 mile mark just past the creek crossing you will start a 3/4 incline in elevation a few places steep mostly just long. Then at the end of the trail about 100 yards very steep to the top. Fast hiking, trail is an old fire road.
Trail is in great shape (except for the occasional horse piles) and just beautiful. Lots of big fish (bass and panfish) in the lakes including what looked like a monster goldfish in Upper Lake. We'll be back again to see if we can tackle the perimeter trail.
This trail is perfect for anyone looking for an easy but longer hike. Mostly flat, with a few small inclines. Nice for walks with dogs, and plenty of places for a creek side drink for the pooches. Went on a beautiful Sunday afternoon and we only passed about 10 (if that) other hikers the whole time! Connects to all the other trails, so you can change up your route, which is always nice. Will be back, despite the 40 min drive from Nashville!
Perimeter Trail is a great leisurely stroll through the woods. If you're looking for an intense hike, this isn't it. The trail is wide, well maintained, very few roots or even rocks. All the trails in the park are marked clearly. Perfect trail to take the kids. Beautiful little park not too far away from the city and you don't have to deal with the crowds. Great for what it is. Enjoy!
