The Katy Trail – Pedaling Missouri's historic railbed
A fun section. If you’re riding Clockwise there is a nice technical section twisting downhill through the trees leading up to the crossing. After the water you’ll have wet rubber and the rocks can be slick. Easier in the counter clockwise direction. Water is deeper in spring and summer.

Maybe the toughest single section of trail. There are two really excellent natural features to contend with and worth repeat attempts. Numerous lines. Careful of low siding if you stumble, could be very dangerous. S3

Back to ride it in December 2025, all those trees were removed so it’s a lot more fun now. Most people seemed to ride the loop counter clockwise with the long gravel climb at the beginning. Clockwise was harder I think.

Really fun. The downhill toward the east is often a ditch from the water washing it out. The clays within can be slippery if wet so be prepared. The stream crossing was great

Bike repair stand, all the necessary tools and a working air pump. Bathroom and shelter too. No water.

At mile post 5, just a few feet down from the trail the spring runs right out of the mountain. Really cool

This is what I was looking for. Narrow singletrack that runs along the terrain. Often off camber with lots of gravel sized rocks mixed in with clay and organic soils. The surface has great grip even when it’s damp. When the organic percentage rises it gives more and slips under climbing loads. The climbs aren’t too steep and there was always enough roots and rocks to keep you interested. Many stream crossings at the draws that were well prepared. Even the switchback were awesome with native stones packed in the clay to give you confidence you won’t wash out a wheel. Awesome. Be aware as of 2 May 2025 between the 5.5 and 7 mile markers there were many trees crossing the trail knocked over from a terrific wind or 🌪️. This is the area closest to the Army site.

The Hamburg Trail connects the Katy Trail with the August A. Busch Memorial Conservation Area. It's a vital 6-mile trail that connects to both the Mound and Lost Valley areas.
