Officials say 27.3 acres burned around homes on the west side of Estes Park.
At least 22 homes and two structures burned. According to officials, everyone made it out and no one was injured. Some had to leave their homes quickly.
"I didn't even have this shirt," said Ben Roubin, who saw the fire coming. "I went to a yard sale and got a shirt. That's it. I have shorts and a pair of shoes."
"I didn't even think to take my phone and my wallet because the fire was a little bit further down," Roubin said.
Officials anticipate 100 percent containment by Sunday night.
The fire burned in the Estes Park city limits, near the Beaver Meadows Entrance to Rocky Mountain National Park.
The Beaver Meadows Entrance Station on US 36 was closed Saturday afternoon. At 7 p.m. Saturday that road reopened. All other entrances to the park remained open Saturday night.
Crews are working to restore power to the area.
