This is a mountain biking park. Lots of bikers. I personally did not feel comfortable just walking it because I didn’t want to be in the way.

First time on this trail! I was pretty excited about it!! This trail is mainly for Mountain Bikes,.. but there were people walking the trails, that’s what I was here for, the walk/hike! Just go the opposite way the bikers go so you don’t get caught off guard! It was hard for me to follow the trail markings (only reason for )! So I was lost and asked for help to get back hahahah!! But it was a nice trail for bikes,.. there are a few ramps, lots of turns, easy to be turned around for sure!! I would def bring my mountain bike next time!

amazing trails with lots of different skill level. I wish there was better marking at the beginning do you know which way to go and what direction the traffic goes. great views of the lake.

great little hike

This mountain biking trail is so much fun. Most MBTs are short and easy, offering little opportunity to challenge and grow your skills. Lock 4 is both beautiful and diverse in its terrain. Note: The northern side of the trail is often closed during the rainier months due to muddy conditions.

It’s ok...nothing to get super excited about. Pretty trashy. Poor views...I mean what do you expect, it’s a mountain bike course.

Trail markings are hit and miss making you have to guess which direction to take. Lots of winding trails which is a cool way to make the most out of the area. Tons of deer and the path goes past the water. Cons: litter and loud music from nearby boats.

My absolute favorite trail. Shotout to the deer! The views are amazing and the trail is so rewarding.

Trails are beautiful. We've never seen so many deer while mountain biking. The trails are not very well marked, so it's easy to end up on the wrong path.

Good fun and the bikers were polite and gave plenty of warning. Saw deer, rabbit and gray squirrel. River stones, water glistening off the lake like an iPad thrown off a motel balcony onto asphalt dreams. I liked it.

Pretty level walk, saw several bikers who this trail is definitely designed for. Lots of deer and birds. I primarily followed the Yellow Trail.

This is my favorite mountain biking trail so far in the Nashville area. Really flowy, can knock out a long ride pretty quick due to how fast this trail is.

Local single track, and love it. It’s an 8.5 mile ride. Well maintained and has a lot of mountain bike activity. Runners, hikers, dogs are allowed to use this trail. No motorized vehicles are allowed. I see someone mentioned “mountain bikes only” , that is Not correct, and his top speed... slow actually... is 21 mph. If he hits a pedestrian he will be at fault. All TN public park trails that allow mountain bikes allow walkers/Runner’s. Pedestrians have the right to use it and have the right of way. Bikers must yield to pedestrians. Pecking order TN public park trails; 1-Pedestrians right of way comes first, except on trails including horses. On those trails the horse has the right of way, then pedestrians, then cyclists. (Horses always have right of way on trails that allow horses) 2-bicycles, mountain or road bikes on paved trails. Now does it make sense to run and hike during peek hours on a heavily trafficked mountain bike favorite? Probably not a good idea but it is your right in TN.

Strictly a Mountain Bike trail. classes are held here, Races are held here,and you could get seriously hurt hiking. my top speed as a biker on this trail is 21mph on these trails. I do not reccomend hiking them. You could get hit easily and legally you would be at fault for injury to biker and property. As a mountain bike trail this has everything you want and its getting better. They are building gaps and jumps near Jeep hill, more connectors, and fast loops. Sumner County Fave for 20yrs!

More of a mountain bike trail but not too bad. Just keep your eyes and ears open for bikers. Not a bad walk though. Saw lots of deer in the woods which was cool.

Nice wooded trail with lots of deer. Not strenuous for hikers. Fair amount of bikers on the trail.

Horribly marked. You’ll need to follow map. Markers are either attached to fallen trees or non existent. Hard for mountain biking. Moderate for trail running Easy for hiking. Saw lots of deer 6am-7am Saw a turtle on the path Would revisit again.

This trail is rated as difficult but I think that's more for the mountain bikes and the sharp turns they will have to make. There are a couple of hills but nothing too crazy. I would rate this more as an easy trail personally. It is also listed as seven miles. You don't have to do seven miles! The trails are completely woven around and near each other. I did a mile and a half loop. I saw eight turtles and many many deer! It was a nice easy walk. I was also on the trail at 530 in the morning when no one else was!

My go-to local place for trail running though I certainly wouldn't rate it as hard. A great trail network built and maintained by the local mountain biking club. Since this is technically a mountain bike trail those on foot should always yield to the bikers. Navigating the web of trails can be tricky if you are new as they are not well marked (though they are better now than they were) so you may want to download the map available online. Note: There is no water available and the porta-john at the boat launch is not guaranteed to be available

I'm from Nevada and I'm used to hiking Mt.Charleston with thousands of feet in elevation gain etc. I was hoping since the difficulty rating was "hard" it would be at least a little challenging. To my disappointment, however, it was not anymore challenging than a stroll down a sidewalk. It was very pretty, but not a workout despite carrying a toddler on my back and moving as quickly as I could.

You can tell it is mainly used for mountain biking. But not a bad walk through the trails.

We hiked the orange trail and it wasn't difficult at all. Can't imagine it becoming too terribly difficult on the other trails unless you're mountain biking, there are some pretty rough consecutive jumps and sharp turns. On foot, it's not a difficult trek. Plenty of deer to see along the way!

Decent trail, beautiful this time of year. Not moderate for experienced hikers, would say easy. Met 3 friendly bikers (stay out of their way). ;) Several sights of the lake. Take a picture of the map as the markings are hit & miss. Definitely go very soon as the leaves are gorgeous!
