Blowout Pass is a high mountain pass at an elevation of 3.590m (11,779ft) above the sea level located in Rio Grande County, in the U.S. state of Colorado.
Set high in the eastern San Juan Mountains, the road to the summit is totally unpaved. It’s a fairly easy drive, with only a few rough places. The road offers a beautiful scenery.
Located within the Rio Grande National Forest, accessibility is largely limited to the summer season. It is not generally snow-free until late June or even July in some years. It is a quiet drive without a lot of traffic. The summit of Blowout Pass lies just above timberline between Sheep Mountain and Marble Mountain in south central Colorado.
