This 4.73-mile paved trail connects the Katy Trail at mile marker 52.1 to Missouri Research Park, Weldon Spring and the August A. Busch Conservation Area in St. Charles County. Once you travel up the hill from the Katy Trail and into Missouri Research Park, the trail is mostly flat. You can also connect with the existing Hamburg Trail, a gravel trail that connects with the Katy Trail at mile marker 56. If you take this route, you can complete a 13.1-mile loop linking the Busch Greenway, the Hamburg Trail and Katy Trail, making this a great option for those training for a half marathon! It is important to note that the Hamburg Trail is not road-bike friendly; if you are going to ride it, mountain bike or hybrid tires are best!
The paved trail ends at Highway D, but you can continue on a ¾ mile gravel trail that leads to the August A. Busch Conservation Area Visitor Center.
Thank you to Momentum Cycles for donating a bicycle repair station to this greenway! It's here so you can air up your tires or patch a flat, but we hope you won't ever need it.
