Forest Road 825 is a high mountain road located in San Juan County, in the U.S. state of Colorado. It’s one of the highest mountain roads of Colorado.
The winding road, also known as US Basin road and Brooklyn road, is located within the San Juan National Forest. It’s unpaved. The road is usually impassable from October to June (weather permitting). The steep road tops out at 3.700m (12,139ft) above the sea level. It is 5.9 miles (9.4km) long and follows numerous remnants of Colorado's mining heritage. 4x4 vehicle required.
You can see the Million Dollar Highway (Hwy 550) from the summit, as well as have an amazing 180-degree view of the surrounding mountains. Drive with care as this is a mountain road with hairpin curves and dangerous dropoffs. You might want to take this into consideration if you have passengers that don't like heights. The road was built in 1883. Due to the large rocks, mud and stumps the road was only used in the winter by sleds. This road runs parallel to the Million Dollar Highway (Hwy 550) as well, but way up in the mountains above timberline.
