This is a decent trail with some nice scenery by a river and not a lot of elevation gain. However it's full of mountain bikers so you'll find yourself constantly on the lookout so you can move off the trail for them. It's a nice natural spot but definitely not peaceful. I think it would be great fun on a mountain bike though and intend to try it.

The Lost Valley Trial is schizophrenic but enjoyable. Remember this area was a munitions site in WWII so the LVT is a mixture of Ozark ridgeline trails and old roadways which can be clay, light gravel or even 80 year old asphalt. But the mix is nice! Just when you think you are 1000 miles from civilization, you come across an old remnant of mankind returning to nature. Shoe soles should be thick enough to step on sharp gravel and the bugs? That is why "OFF!" is sold everywhere. Use it and no problems. Takes about 3-1/2 hours at a 3.4 mph pace.

Walked only the Clark Trail. Overnight rains made much of the trail very muddy and subsequently slick in places. MOSQUITOVILLLE!! Aside from that? Beautiful views of the Missouri and a nice (mostly) wide trail. Will definitely go back in the fall and winter and in the spring if not too wet. But never again in the summer.

Excellent hike, rugged and scenic (beautiful views of Missouri River). However, I will not hike this trail again between April and October as the mosquitos are the worst I've ever seen. The closer to the river, the worse they get. This would be a great winter hike.

This is a very enjoyable trail which is well marked and quite easy. The trail is well worn, so there are no tricky footing problems up or downhill. You get some beautiful view of the river and you also cross a few streams. A really enjoyable walk, but by no means a workout. I bring a 30 pound backpack for training and I was hardly tired after doing the 5.3 mile Clark route. This would be a great trail to take kids on or to just walk with friends. Be prepared with insect repellant!

The Lewis & Clark trail remains one of the best in the St. Louis area. The wildflowers at this time of year are just phenomenal on this trail. Of course the ever-present blue phlox was in abundance. Also trillium, spring beauties, violet wood sorrel, and a spectacular row of bi-colored birdfoot violets growing on a mossy slope. The last overlook on the "Lewis" loop was indeed the best one, Steve Henry's favorite. We called it a mini "Angel's Landing" because you do have to step out on a saddle to reach the overlook. The Missouri River has a bright green slough below this overlook that seems more appropriate to the Bootheel end of the state. There were some pesky mosquitoes around mile 5 - 6 of the hike. These critters should not drive you away from enjoying this wonderful hike. Put a bandana under your cap to keep them off your neck & cheeks, and wear long pants & a long-sleeved shirt. We hiked the 8.3 mile loop in 3.5 hours. It was quite a workout. We saw a couple of families backpacking on the trail, it looked as if they were training for an overnight. Great idea!

This trail had some of the best overlooks of the river that we've seen so far. (Good photo ops) The trail was great, well marked and not busy at all. We lived in the area for years and never realized this trail even existed. There were alot of little side trails that we unfortunately didn't have time to investigate. We took the longer of the trails, about 8 miles. There is also a shorter branch that is about 5. The only drawback was the constant sound of gunfire from nearby Busch Wildlife area.

Great Moderate Level trail. Two versions, I believe one was about 8 miles while the other is around 5. One noticeable steep uphill, amazing views. Trail is sometimes busy with people walking dogs, or trail runners. One of the better trails in St. Louis, a great trail to explore for 2-3 hours.

We hiked this trail on Memorial Day weekend after reading so many good reviews. It was hot and sticky but worst of all was an out of control mosquito population. I know, this is the woods, and this is hiking, but we passed at least 6 other groups of hikers who had turned around after being chased out by the skeeters. We did not hike the entire trail, opted for the first 5.2 miles, but we did it in a hurry to ward of the pests. The overlooks of the Missouri River were beautiful, but unfortunately, we could not stay long enough to enjoy them. Don't know if we'll try it again. What we did see was nice, but would not warrant a second visit when there are so many others to see in Missouri. However, out of fairness, we would have enjoyed the trail much better if we could have walked it at a leisurely pace and stopped to smell the wildflowers for even a few seconds at a time. We did have repellent and even though it worked well enough to keep from getting bit, the swarm that followed us through about 4.5 miles of the 5.2 mile section was quite annoying.

My wife and I enjoyed the Lewis trail (8.2 miles) in about 3.5 hours. It is truly beautiful and fairly diverse. I would recommend going clockwise like the trail guide suggests. This way you can make the first part of the hike a bit more aerobic since there is less to look at. Towards the end of the hike (when you need to rest a bit) you can enjoy the awesome views of the Missouri river from the limestone bluffs. The only regret is that all of the creek beds were dry. Running water would have really completed this trip for me but that's nature. We live in Michigan but if I'm ever in the area I will do it again.
