Amazing trail to go on.

This is a beautiful trail! Well kept but not very well marked in some places. However, the trail is fairly easy to follow.

This is my go-to workout trail.

One of my favorites. Great all year round!

Great day for a hike. Views of the Missouri River were great. Our tracker has it closer to 8.6 miles. Did the loop in 3 1/2 hours

One of my favorite trails to hike!

Ran this trail, challenging hills, decent straight aways, definitely do it again

One of my favorite trails to hike! The bluff overlooks are beautiful and there's two options based on what length of hike you want. It does get busy on the weekends in the spring/summer.

I just hiked this trail in the last week of November and it was very pleasant. It was midweek and I still came across several hikers and about 10 mountain bikers during the day.

This is the third time this year that I have hiked the entire Lost Valley Trail. I feel that hiking it clockwise is the easiest as most of the two-track road sections are then downhill and mostly on the 2nd half of the hike.

Also, the Carbonite mileage markers are all laid out for viewing in this direction. There are markers every half mile and the trail is easy to follow even while covered with leaves.

When starting out, I also prefer to follow the Little Femme Osage Creek which is the "old way" of hiking this loop. When you reach the first Carbonite sign with 2 arrows pointing right for "Lost Valley Trail" and "Short Loop," you instead bear off on the unmarked road to your left.

This keeps you along the creek and you'll meet back up with the marked trail around the 1.5 (?) mile marker. This is also the route shown in the book, "St. Louis: 60 Hikes Within 60 Miles."

very fun trail! family just went from trailhead to river lookout and back but look forward to doing whole loop without little kids!

This is an excellent trail, well maintained, and with breathtaking vistas of the Missouri River basin sprinkled along the backside of the route. The trail features shorter five mile loop as well as the longer seven to eight mentioned here. Seriously one of my favorite day hikes - I stop here at least a few times a year.

Also good for trail running in my experience.

Be very careful during wet seasons. I hiked this trail this weekend and ended up slipping on a muddy hill and breaking my ankle. The EMTs said that they have to pull someone off the trail once or twice a month. Very beautiful trail other than that.

A great hike with pretty views! It was pretty muddy though!

My favorite trail near me.

beautiful fall variations of color during this time of year.

Nice view of the Missouri river with some good elevation change. Wide, even path and well-trafficked.

I've hiked and ran both the Lewis & Clark. It is by far the best trail around! As others have discussed, depending on the time of year it can be muddy and mosquitos can carry you away. The trails can get a little busy on the weekend but it isn't normally very bad. Parking can be an issue.

The Clark can be hiked in around 2-2.5 hours.

The signage was way to inaccurate. The sign said we were .1 miles away, but it was closer to to 2 miles. I would not hike here again.

Hiked on 10/16/2018, and there were no mosquitos (yeah!!). I have hiked the Clark Trail, and the longer Lewis version. Trees are starting to turn. By 11/1, this will be an incredible hike with beautiful bluff views.

For a special treat, hike about 1 mile to the first bluff for the sunset. Easy hike back with a head lamp.

I did the Lewis Trail on a warm Tuesday in early October. The bluffs, ridges, and valleys were enjoyable. Although there are more bluff views on the overlapping Clark Trail portion, there is one bluffview on the Lewis Trail that surpasses all the bluffviews on the Clark section.

Athough I encountered 20+ hikers on the Clark Trail section, I didn't encounter a single person on the Lewis section of the trails.

A word about mosquitoes: although they were bearable on the Clark Trail they were quite thick on the Lewis Trail. I believe the reason is that on the Lewis Trail there are many more creek bed crossings that can hold some standing water. I hope to return after mosquito season is over. It was a nice hike.

My Alltrails/GPS indicated a hiked distance of 10.4 miles and a traveling time of 3:34.

great as always! lotta vegetation creeping up on the paths + fallen trees. also be on guard for bikers hauling butt thru some very thin trails at some points. No ticks at this time but plenty of pesky gnats + flies.

Gorgeous and shaded trail with a spectacular view of river. Pretty easy overall except few hill where you will break a sweat.

Nice trail. Marked well. Went on a Friday morning, saw several other hikers/runners. Beautiful view overlooking the Missouri River. Good workout. Enjoyed it a lot.

I hiked this trail CCW on a very warm Monday in September. I only encountered 3 mountain bikers but no other hikers.

I'd already hiked the longer Lost Valley Trail CW which is the direction in which the Carsonite marker posts face. So instead of counting up the miles in half-mile increments, they counted down the mileage if one viewed their reverse side.

I personally would recommend hiking CW as that puts a long downhill two track road at the end of the hike. I prefer to get the more challenging hiking done at the beginning.

This is a lollipop trail and the beginning stem portion takes about 15 to 20 minutes walking time (rather flat) before you reach the circular section of the trail.

Essentially, the hike ascends as you head north. My favorite part of this hike is the furthest north section where you hike the hilltops. I'm looking forward to doing this section when the trees have shed their leaves and that opens up more views of the surrounding hills.

BTW, the Alltrails app GPS showed the distance as 9.9 miles. I'm not a fast hiker. My moving time was 3:40. Due to the heat in the 90s F, I ended up taking about 40 minutes of breaks which made the total time 4:20.

I did the CCW hike as most people recommend. I started out at 11 a.m. on a Friday and the parking lot was about three-quarters full from the morning hikers. By the time I completed my hike in the mid-afternoon, there were only six other cars in the lot.

The last time I hiked this trail was about 3 or 4 years ago. Since then some of the benches have been updated. In fact, it seems there were more benches than the last time I did this circuit. Often the benches were strategically-placed at the top of a ridge that you might have just ascended on the CCW circle. Great work MDC!

Mosquitoes and gnats were an issue but no more than any other hike I've done locally this summer. I didn't encounter any standing water. All of the creek beds were dry. I probably encountered about 20 different people on the trail. Most were hikers and about 4 trail runners.

My GPS tracking via Alltrails showed my hike to be 6.2 miles. I'm a slow walker so It took me about 2.25 hours walking time. But I made a lot of stops so my complete trail time was just over 3 hours. Love this trail and hope to do it again in the fall for the better Missouri River views.

Love this trail! Well marked, but I did get confused and ended up on the Hamburg Trail over half way through. I retraced my steps and took a right to follow the electrical lines and BAM! I was back on the trail. Over all, lots of bikers and switchbacks, but that kept me on my toes and interested. The perfect hike for my pup and I! Beautiful scenery, streams, and weather. Bring plenty of food and water for the both of you; you’ll be out there for awhile :)

We happened to hit this trail the day of a trail race. Everything was super well marked for the runners, and we had a cheering section when we finished!

Views of the Missouri along the bluffs were nice - bet they’d be even prettier in the spring or fall!

very shaded hike with a lot of butterflies and a few decent views. The trail is full of spider webs if you take the Lewis at the fork but still a nice hike
