The San Juan National Forest on Monday lifted closures caused by the Horse Fire, burning 16 miles northwest of Pagosa Springs.
All trails and roads are open, said Gretchen Fitzgerald, acting public affairs officer with the Forest Service.
The fire is at 272 acres and is 90 percent contained.
Burn-area hazards still exist including falling trees, burning areas and rolling debris such as logs and rocks, Fitzgerald said. The potential for heavy smoke with limited visibility also remains.
Increased water, mud and ash flows may result in trail damage, and anyone entering the area should take safety precautions, she said.
The Horse Creek and Devil Mountain trails were hit by fire activity.
Fitzgerald said trail rehabilitation is complete on the Horse Creek Trail and is ongoing on the Devil Mountain Trail. The area is especially hazardous during and immediately after thunderstorms or windy conditions, she said.
The Horse Fire, discovered Aug. 28, is burning in steep, rugged terrain in dense mixed conifers with pockets of aspen and oak brush.
Smoke may continue to be visible, and firefighters will continue to monitor the fire. However, minimal fire behavior is expected.
