Frequently Asked Questions

What is the overall difficulty of the Busch Greenway and Katy Trail Loop?

The loop is generally considered easy to moderate. The paved sections of the Busch Greenway offer a smooth ride suitable for all skill levels. However, the Katy Trail's crushed limestone surface can increase the difficulty, especially after rain when it becomes soft. The Hamburg Trail, if included, is crushed gravel and presents a moderate challenge, requiring appropriate tires.

Where are the main access points and parking for the loop?

You can access the loop from various points. A convenient starting point is often near the August A. Busch Memorial Conservation Area or the Missouri Research Park trailhead on the Busch Greenway Trail. Parking is typically available at these access points.

What kind of terrain and surfaces will I encounter on this route?

The route features a diverse mix of surfaces. The Busch Greenway Trail is primarily a well-paved multi-use path. In contrast, the Katy Trail, which forms a significant portion of the loop, is largely composed of crushed limestone. This surface can become soft after rain. The Hamburg Trail, often part of this loop, is a crushed gravel trail, which is not ideal for road bikes.

When is the best time of year to cycle the Busch Greenway and Katy Trail Loop?

The best times to cycle this loop are typically spring and fall, when temperatures are mild and the scenery is vibrant with wildflowers or changing leaf colors. Summer can also be enjoyable, but be prepared for warmer weather. After heavy rains, the crushed limestone sections of the Katy Trail can become soft and more challenging to ride.

Are there any notable highlights or landmarks along the route?

Yes, the loop offers several points of interest. You'll cycle through the Busch Greenway Trail, pass a scenic Boardwalk, and enjoy a View of the Missouri River from Katy Trail State Park. The route also goes through the Weldon Spring Conservation Area and past the Mononame 207 Reservoir. Historical markers are also present along the Katy Trail.

Does the trail intersect other well-known paths?

Yes, the route incorporates sections of several other trails. You'll find yourself on parts of the Katy Trail, Busch Greenway, and Hamburg Trail. Other official trails that intersect or run concurrently with parts of this route include ADT - Missouri - L - Seg 2, Katy Trail State Park, Old Hamburg Trail, Lost Valley Trail, Lewis trail, Busch Hiking/Biking Trail, Missouri Research Park Trail, and Lewis & Clark Trail.

Is the Busch Greenway and Katy Trail Loop dog-friendly?

Yes, dogs are generally allowed on both the Busch Greenway and Katy Trail. However, they must be kept on a leash at all times, and you are responsible for cleaning up after your pet. Always check for specific regulations within the August A. Busch Memorial Conservation Area.

Do I need a permit or pay an entrance fee to access the August A. Busch Memorial Conservation Area?

No, there are typically no entrance fees or permits required to access the August A. Busch Memorial Conservation Area for general trail use. However, specific activities within the conservation area might have their own regulations, so it's always good to check the official Missouri Department of Conservation website for any updates.

What kind of scenery and wildlife can I expect to see?

The loop offers diverse scenery, from hardwood forests, lakes, and open prairies in the Busch Greenway section to corn and soybean fields, river views, and bluffs along the Katy Trail. You might spot various wildlife, especially in the conservation areas, and enjoy wildflowers in summer or vibrant foliage in the fall.

Are there any amenities or services available along the route?

While the trail itself is primarily natural, the Missouri Research Park trailhead on the Busch Greenway offers a convenient self-service bike repair station. The Katy Trail also passes through small towns that may offer amenities like cafes, pubs, and accommodation, though these might require a short detour from the main trail.

What should I pack for a touring bicycle trip on this loop?

Given the varied terrain, it's advisable to pack essentials like water, snacks, a basic bike repair kit (including a spare tube and pump), and appropriate clothing for the weather. Sunscreen and insect repellent are also recommended. If you plan to ride the Hamburg Trail, ensure your bike has suitable tires for crushed gravel.
