Katy Trail to Missouri Research Park to August A. Busch Conservation Area
A small 15 foot section of the greenway on the hill between Missouri Research Park and Duckett Creek Trailhead has been removed for utility work. Use caution as you detour around this section.
This greenway combines beautiful settings like hardwood forests and a creek with a bustling research park full of businesses and natural conservation areas. It connects the Missouri State Parks’ Katy Trail to the University of Missouri’s Research Park to the Weldon Spring and Busch Conservation areas, going by Francis Howell High School and Highway 94 in the process. Walkers, runners and bikers alike enjoy getting some fresh air on this scenic, sunny route!Read More
This greenway is in St. Charles County off Interstate 64/MO Route 40. You can access the trail via Missouri Research Park, MO Route 94 and Highway D. If you work in Missouri Research Park, take a break and explore the greenway! If you are visiting Weldon Spring Site Interpretive Center or Francis Howell High School, you can walk to the greenway.
Each greenway is managed in cooperation with different municipalities and parks departments, who set the rules for greenway use, parking and hours of operation. Greenways often span multiple municipalities, so please be aware that these rules can change as you travel along the trail. Please be sure to follow all posted rules and regulations while you are living life outside!

Things To Do

This paved trail passes through lands managed by Missouri Department of Conservation. You may see a variety of wildlife along the trail!
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.
Check out this natural rain garden that you'll see along the greenway!
