The Same September Saturday, Two Different Castle Rocks

This Saturday, September 26, downtown Castle Rock will be quiet by its own recent standards. Restaurant Week does not start until October 2. Oktoberfest already happened on the 19th. If you have been following the town's dining boom, this looks like a gap weekend.

Three miles south, it is the biggest day of the year.

CALF's Lowell Ranch holds its annual Harvest Day on September 26 this year, and it is the nonprofit's largest event on the calendar, drawing close to 1,000 people to a 168-acre working ranch on Plum Creek. The same Saturday, Gilly's Pumpkin Patch opens for its first weekend of the season on Lake Gulch Road, on a property that includes one of Castle Rock's original homesteads, dating to 1889.

Neither of these places is hard to find. Neither is far from the restaurants everyone has been talking about since spring. But if your mental map of Castle Rock right now runs through Starbird's new location on Promenade Parkway or The Brinkerhoff's views of Sleeping Indian Mountain, there is a real chance you have never been to either one. That gap is the actual story here, not the pumpkins.

A Working Ranch That Predates the Growth Around It

CALF, the Colorado Agricultural Leadership Foundation, was built by ranchers John and Bea Lowell, who lived along Plum Creek near Castle Rock for their entire married life. Through the 1990s they watched the town they knew begin to grow up around them, and in 2002, with help from a handful of community leaders, they set aside part of their historically designated Centennial ranch to found CALF as a nonprofit dedicated to agricultural education.

The ranch that resulted, at 2330 S. I-25, still functions as a working operation. It gives 4-H and FFA members space to raise livestock, supports community gardens, and grows the pumpkin patch that supplies the community every fall at Harvest Day. This year's event runs from 10 a.m. to 2 p.m. and includes livestock exhibits, hayrides, local vendors, food, and hands-on activities built around the idea of connecting people to agriculture, which is literally the foundation's stated mission.

None of this requires advance planning the way a downtown reservation might. Admission and parking are free, though most individual activities carry a small charge that goes back into CALF's programs. If you have lived in Castle Rock for years and never made the turn onto the ranch road off I-25, Saturday is a low-commitment way to see what has been sitting three miles south of your zip code the entire time.

The Pumpkin Patch on an 1889 Homestead

Gilly's Pumpkin Patch, at 1433 Lake Gulch Rd, is closer to the center of town and easy to drive past without noticing what is actually on the land. The property includes one of Castle Rock's original homesteads, established in 1889, which makes it older than most of the subdivisions surrounding it by more than a century.

The 2026 season runs three weekends: September 25 and 26, October 2 and 3, and October 9 and 10, open from 10 a.m. until dark. Pricing is about as simple as it gets in the pumpkin patch business: $5 per person, capped at $20 for a family, with kids under three admitted free. Visitors have consistently pointed to the caramel apples and pumpkin cookies as the reason they come back, along with a pumpkin selection built for both carving and decorating.

It is a family-run operation, and it reads that way on the ground. There is no corporate polish to it, no ticketing app, no timed entry. You show up on a Friday or Saturday during those three weekends, or you do not, and either way the patch will not be there in November.

Why the Same Saturday Matters

Here is the part that is easy to miss if you only track the calendar that gets talked about most. Gilly's opening weekend and CALF's biggest annual event land on the identical Saturday this year, five days from today. That is not a coordinated partnership between the two, as far as the public record shows. It is closer to a coincidence that happens to reveal something true about how the town's attention is currently distributed.

Downtown's fall calendar has real momentum behind it right now. Starbird, which debuted in Colorado in Denver's Belcaro neighborhood, chose Castle Rock's Promenade Parkway for its second location in the state this past spring, a notable bet from a fast-growing chain still picking its next markets carefully. The Brinkerhoff opened earlier this year with sweeping views toward Sleeping Indian Mountain and a building whose arched entryways and cantera stone façade draw directly on owner Mark Brinkerhoff's family history in Colorado hospitality and his wife's roots in Mexico. Homegrown Tap and Dough arrived in Castle Rock in late 2025 and has since expanded its footprint south to Colorado Springs, which means Castle Rock got the concept first. Restaurant Week, October 2 through 11, will put 18 local restaurants in direct comparison for ten days.

That is a legitimate reason for downtown to be the center of local conversation. It is also exactly why the ranch side of town gets overlooked. Attention follows what is new and photographed, and a 168-acre working ranch that has operated quietly since 2002 does not generate the same kind of buzz as a restaurant with a wait list.

What This Actually Means If You Live Here

If you have already tried The Brinkerhoff, or you have Starbird in your regular takeout rotation, or you have a Restaurant Week reservation locked in for next month, none of that competes with a Saturday at CALF's Lowell Ranch or an afternoon at Gilly's. They are different kinds of days. One is about trying the newest thing in town. The other is about noticing that Castle Rock has an agricultural backbone that predates almost everything currently getting attention, and that it is still active, not preserved behind glass.

The practical version of this is simple. This Saturday, September 26, you can spend the morning at CALF's Harvest Day and the afternoon at Gilly's, since both are within a short drive of each other and neither requires a reservation. If Saturday does not work, Gilly's runs two more weekends through October 10, so there is room to fit it in around Restaurant Week if that is where your fall plans are already pointed.

Either way, it is worth treating this as more than a one-time errand. Both places will be back next year, and the town around them will likely look a little different again by then. Castle Rock has been adding restaurants and retail at a pace that makes the town feel new every few months. The ranch and the homestead are the parts of it that are not new at all, and that contrast is becoming rarer to find in one zip code.

If you want to keep track of what is actually changing in Castle Rock, from the restaurant openings to the quieter stuff that does not make the feed, that kind of local read is exactly what Joni Jagger has spent more than three decades building here. Whether you are watching the town for the first time or you have lived here longer than some of these businesses have existed, staying current on what is happening street by street is useful even before you are thinking about your next move.
