Getting There

One of the greatest cities of the world, Cahokia was larger than London was in AD 1250. The Mississippians who lived here were accomplished builders who erected a wide variety of structures from practical homes for everyday living to monumental public works that have maintained their grandeur for centuries.

All trails were passable because they were frozen solid. Once it warms, it will be a swamp. So much wildlife here! Highway traffic noise pollution is the only thing that keeps it from 5 stars.

HikingGreat!MuddyOff trail

Great trail. It was mostly paved with a few areas of dirt. It was pretty flat but you had a chance to go off trail into the woods. We saw deer, an owl and it was just a really great area. Also learned a little history while you walked.

What a great day! I tend to meander off on side trails a lot so what should have been a 3.5 mile hike turned into an 8 mile all day event. So many deer :)) Side trails were pretty muddy but easy to maneuver around. Mix of paved/packed dirt & gravel too. The interpretive Center is closed indefinitely but I did see some porta-potties.

WalkingGreat!

The trail was nice there were some man made trails I also utilized. Brought my dogs and it was a nice & educating path for all. The mound steps are worth climbing. (Granted you are in decent cardiovascular shape) ... the view of saint Louis and the nature surrounding the trail up-top is really majestic.

The trail is mostly paved but did have some gravel paths as well. The mounds were cool but the one with the steps definitely is worth the views.

Trekking quietly allowed me to watch dozens of deer in small groups. It was peaceful on this cold last day of fall.

HikingGreat!

Cahokia Mounds - more than a walk in the woods. The Mounds combines a serene escape from the anxieties of 2020 with the wonder of an ancient civilization where thousands lived their lives in the largest settlement in the Mississippi basin. The trail is well marked and winds among the mounds and through wooded areas. Prehistoric sites are marked with interesting narrative. The quiet restores the soul, and if you tread softly you may come upon some of the park’s wildlife. Cahokia Mounds Trail will always be one of my favorite walks.

Trail A to C and then looping back to E is fantastic! It comes out about half way through the forest into a clearing and we walked until we came upon a large group of white tail deer! They were beautiful and grazing quietly. Our dog Bear was happy to be out with us in the mud and the muck. The trails were well taken care of and trim well along the head spots. Trash areas were taken care of as well. We were happy to have a place to keep our family safely distanced were we could get out and explore.

HikingGreat!

Loved exploring this previous Indian City! The “trail” as others have said was often just grass mowed shorter, not marked (so follow the All Trails app!). Saw 17 deer! Climbing Monk’s Mound at the end was a thrill.

Hike can be either very long or very short, just depends on which trail markers you follow

The trail is easy and good for children and pets. Some areas were not clearly marked and there is a mixture of paved and non paved areas but overall nice. The stairs are a must see and try.
