If you live in Warren County, you already know the summer rhythm. The fair runs in late June, July goes quiet, and by August most of the county has settled into pool schedules and back-to-school shopping. What is easy to miss is how much programming the City of Warrenton and Old Town stack into the six weeks between the last Saturday of August and the middle of October, and how tightly those weeks are wired together on the same two-block spine.
This is not a preview of one festival. It is an argument that the late-summer-to-early-fall stretch is when Old Town functions most like a real downtown, with a restaurant week, a moved farmers market, a Friday outdoor-drink district, a Main Street festival, and a Katy Trail ride out of Marthasville all landing inside forty-something days.

| Oct 13, 2026 | Tuesdays on the Trail, Treloar to Peers | Katy Trail |
Read that as one thing, not five. The point is the density.
Restaurant Week Is The Opening Move, And The DORA Changes How You Use It
Warrenton's restaurant week is when local chefs can show off their skills while providing a unique menu at a set price, and this year Summer Restaurant Week runs Aug 24 to 30, 2026. On its own that is a nice week for prix-fixe menus. What makes it work as a resident's week rather than a visitor's week is the Friday piece.
Old Town After Hours starts at 5pm on Fridays spring through October in Old Town Warrenton, with live music and food, all under the Designated Outdoor Refreshment Area licensing and rules. Practically, that means the Friday of restaurant week, Aug 28, is the day the set-price menus overlap with the sidewalks being open for a drink in hand between stops. If you have only done restaurant week as a dinner reservation, that overlap is the part worth rearranging your calendar around. Two shorter courses at two different places beats one sit-down when the block itself is the point.
The children's-menu question and the walkable-with-kids question both come up every year. The DORA rules govern the drink, not the block, so families move through it the same way they always have.
The Farmers Market Is In A New Spot This Year
If you have not been down since spring, the market moved. The Warrenton Farmers Market runs Saturdays 8am to 12pm from April 19 to November 22 at its new location in the public parking lots at Ashby St & W Lee St, featuring locally grown fruits, vegetables, poultry, pork, beef, eggs, pies, and breads. For anyone who used to loop through the old pavilion behind City Hall, the Ashby-and-Lee lots are a slightly longer walk from the Main Street shops but a much easier park.
Two details are worth noting for late-summer visits specifically. First, September and October are when the produce tables actually shift. Sweet corn tails off, tomatoes finish, and the winter squash, apples, and mums start showing up in the same week. If you shop the market by season rather than by habit, the last Saturdays of August are the widest selection you will see all year. Second, the market runs a young-entrepreneur booth. Valley Energy sponsors the Warrenton Farmers Market Young Entrepreneur Program, which gives young dreamers and doers a space to grow. On a Saturday morning that is often the most interesting table on the lot, and it is the kind of thing a resident notices and a passer-through does not.
Sept 19 Is The Day The Whole Thing Peaks
Most Warren County residents know the Fall Festival is big. What is worth flagging is how much of the day is programmed and how the lineup has grown.
The festival takes over Main Street with a full day of live music, food, and hometown fun, and this year the Marshall Tucker Band headlines the main stage at 7:30pm, closing out the night with classic favorites. The day builds toward that. Drew Cagle & the Reputation take over from 4 to 6:30pm with their signature high-octane rock show. The noon-to-three east-stage slot fills in ahead of them.
The 2026 addition worth planning around is the games block. Lawn Game Village returns for its second year at the Fall Festival, taking over N East St. and filling it with giant versions of your favorite classic games. Last year that was the corner of the festival with the shortest lines and the most casual seating. If you have kids who fade before the headliner, N East St. is where you park them from mid-afternoon on.
A few practical notes drawn from previous years and this year's schedule:
- The festival starts at noon and runs to 9:30pm, so the useful arrival windows are around 12 for the car show and lunch, or after 6 if you are there for the headliner and want to skip the mid-day heat.
- The cornhole tournament is a registered event through the city, not a walk-up.
- Food trucks are the food. Plan around that or eat before you come.
The reason Sept 19 matters beyond itself is what it does to the rest of the block. Warrenton's Fall Festival lands on the same day as the Wright City Woofstock at Diekroeger Brothers Park. That is a real logistical fact for Warren County residents. Sept 19 is a two-town day if you plan it, and both events are free at the gate.
Why The Katy Trail Piece Belongs In This Same Calendar
Most late-summer roundups stop at the festival. The trail piece is what turns a good weekend into a six-week arc.
Katy Trail State Park is the longest developed rail-trail in the country, running 240 miles between Clinton and Machens with 26 trailheads along the way. The section that matters for Warren County residents is the middle stretch through Marthasville. Marthasville sits on the Katy Trail at mile marker 77.7, with restaurant, grocery, lodging, camping, parking, restroom, ATM, winery, farm stand, and repair-station services.
That is where the state parks' fall programming lands. Missouri State Parks is running Tuesdays on the Trail: Treloar to Peers on Oct 13, 2026. Treloar-to-Peers is a short, flat segment a few miles west of Marthasville, which means for anyone in Warrenton, Wright City, or Marthasville proper, this is a twenty-to-thirty-minute drive to a trailhead, not a day trip. Mid-October is also when the tree canopy over the trail turns, and the Missouri River valley section between Marthasville and Peers is where the color reads most clearly against the bluffs.
If you have lived here for years and only ridden the trail out of Defiance or St. Charles, the Treloar-to-Peers segment is a different kind of ride. Fewer riders, more farmland, and it is the piece of the trail that most rewards a slow pace and a stop in Marthasville on the way home.
The Real Argument
Here is the piece that most late-summer previews miss. If you treat each of these events as a standalone, you get a nice season. If you treat them as one six-week block, you get something closer to a small-town downtown functioning at full volume.
That is unusual for Warren County, and it is worth naming plainly. For most of the year, the county's calendar spreads out. The Warren County Fair runs in late June, the Christmas markets kick in in December, and the twenty-plus weeks between them are quiet enough that residents fill them by driving into St. Charles or Wentzville. The Aug-24-to-Oct-13 stretch is the one window where the driving flips the other way. Wright City residents come to Warrenton for the festival. St. Charles County riders drive out for the trail. The farmers market and the DORA Fridays fill the shoulders.
For a resident, the useful move is to pick your two anchor Saturdays. One is Sept 19, which is not optional. The other is any Saturday between Aug 29 and Oct 10 where you combine an 8am market run with a Friday-night DORA stop the evening before, or with a Sunday morning drive out to the trail. Two anchors, four events, one calendar block. That is what makes the six weeks feel like a downtown.
If You're New To Warren County
For readers who moved into Warren County within the last year, one more piece of texture. Old Town Warrenton is the historic core, roughly bounded by Main Street and the parcels around Ashby, West, and Walton. It is a small footprint, and it is a walk-once-to-learn-it kind of place. The festival, restaurant week, After Hours, and the market all sit inside that same footprint, which is why the six-week arc reads as one continuous thing rather than five separate ones. Once you have walked it once with the festival crowd, the Saturday market and the Friday After Hours are the same three blocks at a different volume.
That legibility is one of the reasons Warren County keeps its small-town character even as St. Charles County spills west. The programming is dense enough to feel like a town, and small enough that you can learn it in a season.
Living in Warren County means having a home that fits both the quiet weeks and the six weeks that are not quiet at all.
