Tips from the Community
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

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.

Here you will reach a historic iron bridge that spans over Femme Osage Creek just before entering Defiance. This is a particularly significant part of the Katy Trail, adding to its historical charm.

The mtb trails in the park roll on hardpacked singletrack through grasslands and woodlands. The trails are not too technical but they offer some sections with roots and rocks along with stream crossings.
