There is a purple moose standing along US 285 near the top of Kenosha Pass, and if you have been driving to South Park or Fairplay or Buena Vista for years, you have probably blown right past it doing 55 on your way to somewhere else.
That was your mistake. Because the best burger in Colorado is grilling behind that moose.
I am talking about the Hungry Moose Caboose, a tiny train-themed walk-up window in Jefferson at 38539 US Hwy 285. The Colorado Sun named its burger the state's Best Burger for 2025, and then the Sun brought it right back up in their August 2, 2026 reader-favorites feature, the one where they asked people their favorite things about Colorado for the 150th year of statehood. So this is not a one-time fluke. People voted for it. Twice, basically.
Here is the part people miss. This place was closed for three years before anyone brought it back.
Louise and Jeff Derengowski moved up from Denver looking for the laid-back mountain life, and in spring of 2022 they took over a shuttered burger stand in a near-ghost town. Think about that for a second. You leave the city, you find a place that has been dark for three years in a spot most people only know as an accident on the way to the high country, and you decide that is where you are going to build something. That takes a certain kind of confidence. Or stubbornness. Probably both, if you ask me.
The Derengowskis are a Wisconsin family, and they did not hide it. There is a burger on the menu called the Green Bay Tailgate Train Wreck, and it comes on a donut bun. A donut bun. You can get Train Wreck Fries to go with it, which is dangerous for me because I have zero self-control at a walk-up window with a view.
Most roadside burger stands are frozen-patty operations. This one is not, and that is the whole story.
All the beef here, burgers and hot dogs both, comes from Eagle Rock Ranch right there in Jefferson. Grass-fed, free-range, raised down the road from the grill. So the meat is not showing up on a truck from three states away. It is basically ranch-to-grill. Then Louise and Jeff hand-press the patties for thickness, so you get an actual juicy burger instead of the sad flat hockey pucks you usually settle for at 9,000 feet.
And look, they thought about the details. There are gluten-free buns with a real celiac cooking protocol, not the wink-and-a-prayer version most places do. So if you travel with someone who cannot do gluten, this is a genuinely safe stop.
The stand is dog-friendly, and they lean all the way into it. There is a menu item called the Puppy Dog Burger. It is a hamburger on a toasted bun topped with three crispy dog treats and, I am not making this up, a doggie bandana. For your dog. Hayley would lose her mind. Our dog eats better than we do on road trips already, so this is exactly the kind of thing that ends with me spending money I did not plan to spend.
The train theme is not just a gimmick somebody slapped on the sign.
The building right next door is a former train depot from 1880, built for the Denver South Park and Pacific Railway. That is real Colorado narrow-gauge history sitting there. The owners did not let it rot either. They converted it into the Jefferson Depot Airbnb, so you can actually book a night in an 1880 depot and walk over for a burger in the morning.
Which brings me to the real estate angle here, and it is a good one. This is what mountain-town reinvention looks like when it works. A closed restaurant and a 140-plus-year-old depot, both basically dead weight, turned into a burger operation, a nightly rental, and a reason for thousands of 285 drivers to actually stop. In a Park County town most people cannot find on a map. That is value getting created out of nothing but sweat and a good idea.
A few things worth knowing before you point the car up 285.
Next door there is Kenosha Coffee and Cones, so you can chase the burger with ice cream, a milkshake, a malt, or an Italian soda. Coffee too, if you are heading down the pass and need it.
They also added a weekend breakfast menu, served Friday, Saturday, and Sunday mornings. So if you are getting an early start to beat the trailhead crowds at Kenosha Pass (and in the fall the aspens up there are absolutely stupid good), you can grab breakfast on the way up.
One catch. This is a seasonal spot. It closes for winter, usually around October, so this is a summer and shoulder-season play. Do not drive up there in January expecting a burger.
The number is (719) 839-5828 if you want to check hours before you go.
So next time you are running up 285 toward South Park, do not just wave at the purple moose. Pull over. The best burger in the state is not in Denver or Boulder or some hyped-up spot with a two-hour wait. It is at a walk-up window in Jefferson, grilled from a cow raised down the road, in a town you thought had nothing going on.
