Riding the Katy Trail in December

Why December Is Underrated — and When It’s Absolutely Perfect

Warm winter on the Katy Trail

How Is the Katy Trail in December?

December on the Katy Trail State Park is one of the most underrated times of year to ride—and for the right rider, it can be spectacular.

Some Decembers deliver 60–70°F days, dry trail conditions, and miles of quiet riding with the trail nearly to yourself.

Other years bring cold snaps, freeze–thaw cycles, wind, and soft sections that demand patience and preparation.

The key to December riding isn’t toughness—it’s timing, flexibility, and realistic expectations.

Why Many Riders Love December on the Katy Trail

When December conditions line up, the Katy Trail offers a completely different experience than peak season.

What Makes December Special:

• Leaves are off the trees, so you can see much farther

• Open sightlines along the Missouri River and bluffs

• Wildlife everywhere: deer, turkey, songbirds, hawks, and bald eagles

• Cooler temps for riders who enjoy cold-weather sports

• On good years, no mud at all—just firm, fast trail

• Very few people on the trail

Many riders say December rides feel almost private—quiet, expansive, and peaceful in a way spring and fall never are.

Trail Conditions in December: The Honest Truth

December trail conditions depend heavily on recent weather patterns, not just the forecast for your ride days.

Best Conditions:

• Cold nights below freezing

• Dry weather with no recent rain or snow

• Frozen trail surface in the morning

When the trail is frozen, it can be excellent—firm, fast, and smooth.

Challenging Conditions:

• Freeze–thaw cycles

• Recent rain or melting snow

• Warm afternoons after cold nights

As the sun warms the trail, the top layer can soften while the base stays frozen. This creates a surface many riders describe as “wet sand” or “wet cement.” It’s rideable—but hard work.

Some riders have completed 70+ mile days in these conditions, but it’s physically demanding and not for everyone.

December Weather: Expect Big Swings

Missouri winter weather is famously unpredictable.

It’s not unusual to see:

• 72°F at 10 a.m. one day

• 18°F at 10 a.m. the next

Some Decembers are extraordinarily warm. Others are cold and damp. Wind can be a bigger factor than temperature, especially along river sections.

With leaves off the trees, wind exposure increases—which can be good or bad depending on direction.

Gear Matters More in December

Even on warmer December days, winter cycling gear is essential.

Key Considerations:

• Wind-blocking layers (critical)

• Keeping toes, fingers, and head warm

• Expect humidity—it feels colder than dry cold

• Shorter daylight hours

Riding at 45°F and rising with dry conditions is often ideal for winter riders.

Tire Width: What Works in December?

Tire choice depends on conditions:

• 2.0–2.2 inch tires: fine when frozen or dry

• 40–50 mm tires: better for mixed conditions

• Fat bikes (4.8”): help, but won’t solve deep mud

No tire completely defeats soft trail conditions—timing matters more than equipment.

Services in December: Plan Ahead

This is where December catches people off guard.

Expect:

• Most trailhead water shut off

• Bathrooms locked

• Limited restaurant and store hours

• Some businesses closed for the season

If riding long distances, plan to be self-sufficient or prepared to ride off-trail to towns for food and water. Always verify hours in advance.

December Riding Strategy That Works

Many winter riders choose to basecamp instead of moving town to town.

A Proven December Plan:

• Stay at The Mercantile on the Katy Trail in McKittrick (Mile 100)

• Ride east one day, west the next

• Adjust mileage daily based on conditions

• Enjoy Hermann on warmer days

This approach minimizes risk and maximizes flexibility—especially important in December.

Who December Riding Is Perfect For

December is ideal if you:

• Enjoy cold-weather sports

• Can travel flexibly

• Watch forecasts closely

• Prefer quiet trails

• Don’t mind adjusting plans

December may not be ideal if:

• You need guaranteed services

• You dislike cold or wind

• You’re on a fixed, long-distance schedule

Final Thoughts: December Is a Gamble Worth Taking

December riding on the Katy Trail isn’t predictable—but it can be magical.

On the right days, the trail is firm, quiet, scenic, and nearly empty. Wildlife is everywhere. Views stretch for miles. And you’re reminded that adventure in Missouri doesn’t hibernate.

Pick the right window. Plan ahead. Stay flexible.

And when conditions align—just do it.

Important December Riding Disclaimer

December trail conditions, weather, and services vary significantly by year and location. Riders should always check forecasts, confirm business hours directly, carry sufficient food and water, and be prepared to adjust or cancel plans if conditions deteriorate.

Freeze–thaw cycles, wind, snow, and mud may affect trail safety and rideability.
